Autogard torque limiters provide mechanical protection for drive systems in many industries, including mining and quarrying, that operate under uneven torque loads, shock loads and overload conditions.

Autogard 820 Series torque limiters are particularly well suited in mining applications, like horizontal Semi-Autogenous Grinding (SAG) mills, where reliable power transmission is critical and where sudden jams or load fluctuations can cause significant damage to motors, gearboxes and couplings. In these challenging applications, torque limiters act as a protective interface, disconnecting the drive as soon as a preset torque threshold is exceeded.

Autogard torque limiters protect drive systems by mechanically disengaging when the torque limit is reached. Once the overload condition has cleared, operation can resume without damage to upstream components. This system reduces the risk of mechanical failure and limits unplanned downtime in continuous process operations.

In ball and SAG mill applications, uneven torque loads are unavoidable due to the crushing process itself. Autogard 820 Series torque limiters are designed for very high-torque drives in heavy-industry environments and provide bidirectional protection with a high degree of accuracy. The modular design allows trip torque capacity to be set to suit specific operating conditions, with repeatable disengagement in the event of overload. After a trip event, modules can be reset quickly using standard tools, allowing maintenance teams to restore operation with minimal delay.

“In many industries – including mining, cement, sugar milling, bulk materials handling, wineries and breweries – conveyor blockages and process surges are common,” says Carlo Beukes, Business Unit Manager for BMG’s Power Transmission division. “Autogard torque limiters efficiently protect high-value drive equipment against overload, preventing damage and minimising downtime in operations that depend on continuous production.”

Unlike conventional shear pins or friction-based devices, the Autogard system offers repeatable disengagement accuracy, with low maintenance requirements. Torque capacities across the range extend from approximately 3 Nm to 45 000 Nm and are suitable for light, medium and heavy-duty applications, including conveyors, crushers, mixers and process machinery. Units can be installed in standard shaft or coupling configurations in both new installations and retrofit projects.

BMG’s Regal Rexnord power transmission components also include industrial gear units, low-speed backstops, idlers, couplings, bearings and shaft locking assemblies. Other important components are Falk True Hold low-speed backstops and Rexnord Omega and Viva elastomeric couplings.

BMG’s power transmission specialists provide support throughout the specification and implementation process, including sizing, alignment and commissioning assistance. This technical solutions capability is enhanced by the company’s established branch network, ensuring ongoing service for critical drive components in the field.

These compact, invertible Hansen I4 units are engineered to deliver high torque capacity, dimensional accuracy, and operational reliability in both underground and surface applications, while ensuring minimal maintenance requirements and extended service life.

Important advantages of the Next Generation Hansen I4 programme – which combines cost optimisation with retained design integrity – include reduced lead times and OEM-backed technical support throughout Africa.

“By standardising the core materials required in key Hansen I4 models, we are able to improve supply efficiency, while maintaining the original torque ratings, gear geometry and bearing performance required for heavy-duty mining and conveying applications,” explains Barry Stoltz, BMG’s Gears Regional Manager, Electro-Mechanical division. “The result is a robust and reliable unit that conforms with Hansen’s global design standards and technical specifications, but with improved availability for operations throughout the African continent.

“BMG has streamlined production and supply processes, reducing delivery lead times to a maximum of four weeks. This shorter turnaround time supports plant uptime strategies for our customers, where conveyor availability is directly linked to output and revenue.”

The revised I4 platform incorporates a standardised bill of materials across the core RDD, RDE and RDF configurations, with gear ratios between 16:1 and 35:1. This rationalisation enables bulk procurement of critical components, including bearings, seals, spacers, nilos rings, bolts and nuts. As a result, accessibility and cost-efficiency are improved, with no compromise on performance, even in arduous conditions. Local sourcing further strengthens supply continuity for the African market.

The Hansen I4 is built around precision-manufactured helical gearing and designed to AGMA-rated standards to balance high torque density with controlled noise levels. High torque geometry is applied to low-speed gears, while high-speed stages are configured to reduce noise emission. Detailed service factor and operating life calculations underpin the shaft and bearing design, ensuring suitability for continuous-duty conveyor and mining drives.

Installation flexibility is a core feature of the Hansen I4 range. The gearbox can be inverted through 180 degrees to accommodate left- or right-hand drive arrangements, reducing inventory requirements and simplifying plant layout. A robust horizontally split housing facilitates easy inspection and maintenance, while horizontal or vertical shaft configurations provide adaptability for different mechanical interfaces. Hansen’s Oil-Lock sealing arrangement ensures long-term oil retention and reduced contamination risk in abrasive environments.

As the official OEM for Hansen gearboxes in Southern Africa, BMG is authorised to repair Hansen IGUs in accordance with the manufacturer’s documented procedures, maintaining original tolerances and operating specifications. Each unit undergoes detailed incoming inspection, full disassembly and dimensional verification of housings, shafts and gears before reassembly to factory-defined clearances. Bearings and seals are replaced as standard, fasteners are torqued to specified values and gear contact patterns are verified to meet correct mesh alignment requirements.

No gearbox is released before a controlled running test confirms mechanical, thermal and lubrication performance, including checks on temperature, noise and oil tightness.

BMG’s Next Generation Hansen I4 range meets the requirements of customers seeking a standardised, high-torque, cost-efficient IGU, with reduced lead times and local OEM-backed technical support.

“What’s impressive about the RN series, is not only are these the first metric-sized ISO unitised plummer block bearings available locally, but these bearings, with a two-piece outer race, are interchangeable with existing SN500 plummer blocks using 222**KK bearings. For users this means high efficiency, optimum productivity, reduced downtime and a lower total cost of ownership,” explains Gift Davhana, BMG’s Product Specialist, Bearings division. “The RN series has been designed for dependable performance and extended service life in harsh environments, with extreme contamination and elevated operating temperatures. Typical applications include elevators, screw conveyors, feeder breakers, roll crushers, conveyor pulleys and fans.

“Although there is always pressure on ‘price’ in the procurement of engineering components, BMG specialists advise customers to appreciate the value of the investment in quality branded products, to reduce total cost of ownership. The RN series is shaft ready, with pre-assembled bearing units that eliminate the need to set clearance or add grease. The unitised solid one-piece housing enables effortless replacement of existing bearings. The Shurlok tapered adapter, for easy-on/easy-off shaft mounting, provides quick installation and removal of bearings and delivers the best-in-class shaft grip for maintenance-free performance. Added to this, concentricity is enhanced, which minimises vibration and extends service life. Auxiliary covers provide contamination protection in extreme conditions and also extend bearing life.

Features 

“This range has been designed to overcome problems associated with conventional bearings, including premature failure resulting from contamination, improper installation, heavy loading vibration and from mismatched bearings to specific application requirements. Difficult and time-consuming bearing removal and seal replacement are also common problems in the field.

“An advantage over conventional bearings to reduce contamination and extend the service life of bearings, is a modular 2-piece outer ring design that facilitates effortless onsite seal changes, in less than three minutes.”

Notable features of the RN series include an industry-leading misalignment capability of 2°, standard dimensions for quick and easy drop-in replacement and field adjustable clearance to accommodate higher temperatures and higher speeds, for reduced maintenance intervals and longer bearing life. A steep roller contact angle also extends service life in high thrust load applications, like fans and blowers and vertical shaft or helical gear applications. Oversized rollers offer higher load ratings and a carburized inner ring allows flexing yet provides shock and fracture resistance.

Installing a solid housed Shurlok bearing is up to 80% faster than installing a traditional plummer block and unlike the conventional plummer block assembly with multiple components, the RN series unitised plummer block unit has no loose components.

The BMG team is committed to working closely with customers in all industries to investigate the source of bearing problems and to provide cost-efficient solutions for optimum productivity of machinery, extended service life of the system and minimal maintenance requirements.

“BMG’s Fluid Technology division’s strategy to meet constantly changing market demand encompasses the introduction of new products, with the latest developments in design technologies, materials and coatings,” explains Willie Lamprecht, Sales Manager, Fluid Technology division, BMG. “Pinch valves have been added to our product offering, enhancing our wide range of industrial slurry valves, that also includes butterfly, gate, diaphragm, ball and check valves.

Range

“The Fluid Technology team boosts specialist services with dependable technical support to customers in all sectors, to ensure optimum safety, efficiency and extended service life of every system. Failure of a valve and subsequent leaking of corrosive media can have devastating effects on the safety of personnel and equipment, leading to premature system failure and costly downtime. With broad technical capabilities, our specialists advise on correct valve selection and installation for every application and are able to solve problems, even in corrosive environments, where conventional components have failed after short periods of service.”

BMG’s range of pinch valves – which meets stringent quality and safety specifications – is available with nominal bore sizes from DN50 up to DN500, in either short or long open frames, with safe working pressures up to 25 bar. These valves can be tailored to suit specification application requirements, with Stainless Steel frames if required.

Standard pinch valves can withstand operating temperatures between -20ºC and +80ºC and higher temperatures on request. These valves have manual, gearbox, pneumatic and hydraulic actuation. The working element of a pinch valve – also known as a clamp valve – is an elastomeric tube or sleeve, which can be squeezed at its mid-section by a mechanical system until ultimately the tube walls are pinched or clamped together, producing full closure of the flow path. This flexible tube is either exposed (an open frame) or enclosed (a closed frame) in a body.

In its simplest form, a pinch valve can comprise a length of elastomeric tube, fitted with a pinch bar mechanism, incorporating a closure stop to prevent over-pinching of the tube. More commonly, the moulded rubber tube is housed in a metal body, which also incorporates the pinching mechanism. This can be a simple screw operated mechanism, where the pinch is applied only to one side of the tube, or a differential screw controlling two pinching mechanisms working in vertical opposition.

BMG’s open frame pinch valves, which have been developed on the successful design of BMG KLEP’s patented FPV diaphragm valves, are 100% locally manufactured and are available in many different materials, with various pressure ratings, to meet exact requirements.

This range is available from BMG with different linings – for example, soft rubber, hard rubber, Butyl rubber, Halar and jumbo rubber. The lining and diaphragm design increases the service life of the valve, due to high abrasion and chemical resistance properties of individual linings and diaphragms.

BMG’s full range of industrial slurry valves is highly efficient for the control and isolation of abrasive slurries in many industries, including power generation, chemical and petrochemical, cement handling, water treatment, mining, quarrying, pulp and paper. BMG’s extensive range of components for fluid technology systems and general industrial applications comprises valves, hydraulic hoses and fittings, accumulators, cylinders, heat exchangers, pneumatics, hydraulic motors and hydraulic plumbing, as well as pumps and reservoir accessories.

Fluid technology services also cover project engineering and consulting, cylinder design and manufacture, training, repair and testing, as well as onsite container services.
