chain tensioning wheels are supplied because a established with integrated ball bearings. The bearings are sealed on both sides and lubricated for life, therefore they are maintenance-free. The wide inner band ensures perfect mounting without washers. Ball competition and sprocket are press-fitted to guarantee a secure, long term connection. The sprocket is made from metal with a mechanical strength 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.
