Floating Roller Chain Tensioners
Mount these tensioners directly onto your chain drive. They have adjustable straps that take up slack and apply constant tension. Because they engage with the side plates instead of the rollers, they increase the life of your roller chain.
UHMW tensioners are stronger and more durable than PTFE tensioners.
PTFE tensioners handle temperatures up to 450° F, more than twice as high as UHMW and titanium models.
Titanium tensioners stand up to harsh and dirty environments. They're stronger and more durable than plastic tensioners. And with a low coefficient of friction, they work with chain that has little or no lubrication.
