For tensioning roller chains. The sprocket set can be combined with all tensioning elements to form a ready-to-install chain tensioner. The ball bearings are sealed both sides, permanently lubricated and maintenance-free.
The sprocket can be moved on the screw and thus adapted to the chain track. With the duplex and triplex version, precision spacer sleeves ensure correct chain guidance.
Rigid mounting without a tensioning element is also possible. Can also be used as an idler sprocket.
