chain tensioning wheels are supplied as a set with integrated ball bearings. The bearings are sealed on both sides and lubricated for life, so they are maintenance-free. The wide inner ring ensures perfect mounting without washers. Ball race and sprocket are press-fitted to guarantee a secure, permanent 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) are available on request.
To be used with roller chains DIN ISO 606, as tensioning wheel on tensioning element, as spare wheel for chain tensioners or universally as return chain or tensioning wheel
Ready-to-install chain tensioning wheel set complete with mounted ball bearing
Tensioning elements and sprockets make up a complete, ready-to-install, continually-tensioning torsion chain tensioner
In order to get a complete chain tensioner both tensioning element and sprocket have to be ordered
Can be mounted at the deflection and tensioning points
Permanently lubricated 2-Z bearings guarantee perfect running
