Chain tensioner iwis-Spannbox

The tensioning pressure of the newly developed chain tensioner is transferred via the sliding pad to the chain by means of a recoilattenuated gas-filled spring device. By using the familiar gas-filled spring device with recoil attenuation a consistent tensioning pressure is attained along the entire tension path. This key advantage compared with the previous design of chain tensioners with a flat spiral spring (sharply falling spring characteristic), guarantees a an almost vibration-free chain drive. Advantages: • Consistent tensioning pressure along the entire tensioning path • Vibration and noise attenuating • Low coefficient of friction • Wear-resistant • Self-lubricating • Range of application from -30 to +80°C
