chain tensioning wheels are supplied because a set with integrated ball bearings. The Chain Tensioning Wheels With Ball Bearings bearings are sealed on both sides and lubricated forever, therefore they are maintenance-free. The wide inner band ensures perfect installation without washers. Ball race and sprocket are 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 suitable for roller chains from size 06 B-1 to 20 B-1. Chain tensioning wheels for duplex roller chains and roller chains to ANSI standard (DIN 8188) are available on request.
