chain tensioning wheels are supplied as a set with integrated ball bearings. The bearings are sealed on both sides and lubricated forever, so they are maintenance-free. The wide inner ring ensures perfect mounting without washers. Ball race and sprocket are Chain Tensioning Wheels With Ball Bearings press-fitted to guarantee a secure, long lasting connection. The sprocket is made from metal with a mechanical power of 490-600 N/mm2.
These tensioning wheels are ideal for roller chains from size 06 B-1 to 20 B-1. Chain tensioning wheels for duplex roller chains and roller chains to ANSI regular (DIN 8188) can be found on request.
Application areas
