Tensioner pulleys

Tensioner pulleys provide precise guidance and constant belt tension in the belt drive. They can either be mounted rigidly or combined with the tensioning elements to belt tensioners. Tensioner pulleys increase the wrap angle on belt drives and thereby transmit higher performance. They enable a change in the rotational direction of the connected aggregates. In combination with belt tensioners, they also compensate for operational belt stretching.

Tensioner pulleys of the DT® Spare Parts brand consist primarily of ball bearings and belt tensioner. The ball bearings are filled with heat-resistant grease and perfectly sealed on both sides. Various materials are used in the production of belt tensioners, depending on the technical requirements, for example deep-drawn sheet steel, turned bar, cast steel or Polyamide 66 with glass fibre content. Tensioner pulleys of the DT® Spare Parts brand are designed for a maximum temperature of up to 120°C and 6 000 RPM.

The precision-machined contact surfaces of the belt tensioner ensure optimal installation of the drive belt, low wear and minimal operating noise.
