6.31011 Belt tensioner

Belt tensioners are used to ensure the optimal tension of the belt and V-belt as well as for damping the belt vibrations. These occur during belt drive operation and through load changes of the motor or auxilliary units.

This kind of belt tensioner from the brand DT Spare Parts is characterized by the maintenance-free double-row ball bearings, which are sealed on both sides and, therefore, 100% protected against dust and water. Thanks to high-quality plastic washers, the tension springs inside the housing are protected against premature wear.  The washer is centrically sealed, so that it can be subjected to high loads. The outer lock washer is  constructed in such a way that it further supports the effective damping.

Tips & Tricks

All components of the belt drive must be inspected when the article is replaced.
The installation position of the belt tensioner is predetermined by the fixing bolt at the front. The mounting surface must be clean and free from foreign objects. Because of the extreme spring force, the article may not be opened. The torque of the mounting bolt must be observed, as the pre-tension and function of the belt tensioner is impaired if the torque deviates.

The tensioning or releasing may only be carried out with the specified special tool. Plain bearing bushings ensure a high level of stability and minimum Play. A half-inch square box spanner e.g. a ratchet wrench is an alternative. The belt must be correctly positioned to ensure optimum belt Tension.
