Rubber Block Series Tensioner

Proven to be an effective way for tensioning chain and belt drives in most applications, the TransDrive Rubber Block Series Tensioner has been designed to ensure optimal performance and longevity with reduced maintenance issues. From conveyor systems to automotive engines, the Rubber Block Series Tensioners deliver consistent force, minimizing belt slippage and maximizing efficiency.

Features/ Benefits

  • A one nut mounting system, which allows for 360º rotation.
  • Can be pre-tensioned by up to 30º, this means that as the chain or belt stretches, the tensioner automatically takes up the slack as the elastomeric elements automatically adjust the drives tension.
  • Chain and Belt life is increased by as much as 30%.
  • Elastomeric parts absorb vibrations and shock loading.
  • Maintenance Free – no metal on metal parts, lubrication free.
  • Impervious to dust and dirt, temperature -40ºC to +80ºC.
  • Two holes are provided on the arm, allowing two different levels of force to be generated: “normal” and “hard”. The “hard” setting deploys approximately 25% more force.
