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.
Application areas
To be utilized with roller chains DIN ISO 606, since tensioning wheel on tensioning element, as extra wheel for chain tensioners or universally since come back chain or tensioning wheel
