chain tensioning wheels are supplied as a arranged with integrated ball bearings. The bearings are sealed on both sides and lubricated forever, therefore they are maintenance-free. The wide inner ring ensures perfect mounting without washers. Ball competition and sprocket are press-fitted to ensure a secure, permanent connection. The sprocket is made from steel 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 tires for duplex roller chains and roller chains to 
ANSI standard (DIN 8188) are available on request.
Application areas
