chain tensioning wheels are supplied because a arranged with integrated ball bearings. The bearings are sealed on both sides and lubricated forever, therefore they are maintenance-totally free. The wide inner band ensures perfect installation without washers. Ball race and sprocket are press-fitted to ensure a secure, long lasting connection. The sprocket is manufactured out of steel with a mechanical strength of 490-600 N/mm2.
These tensioning wheels are suitable 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.
