Rosta SE maintenance free tensioner devices for chain drive and belt drive. The SE standard tensioning systems prevent necessity to compensation of lengthening due to age and prevents slipping of the belt. Also dampens the noise level. Through aging extension of the chain and belt occurs. The SE tensioning device automatically corrects this extension and in such prevents the sagging and beating of the chain and excessive slippage of the belt. The tensioner devices offer a quiet chain run and reduces wear on rollers and bearings.

  • Various versions with a working temperature range up to 120°C (standard tensioners 80°C).
    In the standard catalog tables are available for selection of the type of tensioner with sprocket sets and other accessories that can be applied with different types of chain, according to DIN8187.
