Bosworth is South Africa's leading conveyor belt pulley manufacturer, producing a wide range of pulleys, including tail, snub, and take-up pulleys used in the global materials handling industry.
These range from T-Bottom and Turbine pulleys to Grease-Filled and Spiral, self-cleaning bearing-type pulleys. Pulley heat treatment, stress relieving, lagging, and static balancing are all performed in-house, and all pulleys can be crowned or lagged.
Most suited for low to medium duty applications, with shaft diameters typically smaller than 200mm. The shafts on these pulleys may be removed for easy replacement, thus reducing possible repair costs. The hubs are designed to allow for flexion, thereby preventing high-stress loads on the locking assemblies or welds.
Designed for heavy-duty applications where there is a demand for high torque transmission. The pulleys are supplied with shaft diameters larger than 200 mm, depending on the torque requirements.
The “grease filled” pulley is fitted with internal bearings and a stationary shaft in order to protect the bearings in very dirty operating conditions. These are available in non-driven applications only. These pulleys are mounted on the conveyor structure in various ways on the stationary shaft.
Wing, slatted or self-cleaning pulleys are designed with open wing-type profiles that help shed material build-up from the belt contact area. They are commonly used in tail, bend or take-up positions where carry-back or spillage may be present, helping to reduce belt damage, improve tracking stability, and extend pulley and belt life.
Spiral pulleys feature a helical bar or spiral profile around the pulley face. This design assists with self-cleaning by directing material away from the centre of the belt contact area, reducing build-up, improving belt contact, and helping to limit belt tracking issues caused by trapped material.
Hold-down pulleys are used to control the belt path and keep the belt in contact with the required conveyor profile, particularly where the belt may tend to lift due to changes in direction, convex curves, light loading, or dynamic operating conditions. They assist with belt stability, alignment, and safe operation of the conveyor system.
Stub-shaft pulleys are manufactured with short shaft extensions rather than a full through-shaft. This arrangement can reduce overall shaft length and mass, simplify certain installation layouts, and suit applications where space, mounting arrangement, or maintenance access is limited. Stub shafts are typically supported by suitable bearings or bearing housings.
Drum winches are used for controlled lifting, pulling, positioning, or tensioning of heavy loads by winding rope or cable onto a rotating drum. They are commonly used in mining, materials handling, marine, and industrial applications where reliable and controlled movement of equipment or loads is required.
