chain tensioning wheels are supplied as a set with integrated ball bearings. The bearings are sealed on both sides and lubricated for life, therefore they are maintenance-totally free. The wide inner ring ensures Chain Tensioning Wheels With Ball Bearings perfect mounting without washers. Ball race and sprocket are press-fitted to ensure a secure, long term connection. The sprocket is made from steel 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 regular (DIN 8188) are available on request.
