chain tensioning wheels are supplied because a established with integrated ball bearings. The bearings are sealed on both sides and lubricated for life, so they are maintenance-totally free. The wide inner ring ensures perfect installation 
without washers. Ball competition and sprocket are press-fitted to ensure a secure, long lasting connection. The sprocket is made from 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 wheels for duplex roller chains and roller chains to ANSI standard (DIN 8188) can be found on request.
Application areas
To be utilized with roller chains DIN ISO 606, since tensioning wheel upon tensioning element, as spare wheel for chain tensioners or universally as return chain or tensioning wheel
