Miki Pulley Tensioners

Use suspension unit in tensioning, as a pressure roller, or as a damper.

An arm is mounted on a suspension unit and rollers and sprockets are set, enabling use in tensioning, as a pressure roller, and as a damper. With a flanged outer shell and mount that secures with a single bolt, it is easy to set. A wide range of loads can be accommodated, since the idler’s mounting bore can be selected for a range of usage loads. SE models have no idler while RSE belt tensioners come with roller idlers. We also offer NSE tensioners, which come with sprocket idlers.
