Tensioning rollers / Idler pulleys / Universal tensioners Info

Tension rollers, sprocket sets, chain slides and belt tensioning pulleys can be used to adjust the preload force in rotary drives with fixed shafts. They do not transmit power, but can improve performance.

Further information about our tensioning pulleys, tensioners, idler pulleys, sprocket sets, chain sliders and universal tensioners:

Tension rollers help to improve performance in multi-shaft drives with small wrap angles. Tensioning pulleys can prevent thrumming in drives with small pulleys and large shaft distances. Please note that the use of tensioning pulleys in belt drives leads to an increased load on the belts due to the bending cycles.

Out type B tensioning rollers are grease-lubricated and double-mounted on deep-groove ball bearings. They are available with a cam or flange with a smooth contact surface, with and without sheaves. Type B/EO is available with a cam and toothed contact surface for belts with the profiles: T5, AT5, T10 and AT10. The heavy-duty Type M series with cam is fitted with high quality deep-groove ball bearings. They are cantilever-mounted on the machine wall. The Type BSR light-duty series without a cam is lubricated with DIN 51852-K3K grease. It has proven itself as a tensioning and idler pulley for light-duty belt drives, e.g. for toothed belts with profiles T2.5; T5 and AT5.
