Tensioner Pulley Bearing Applications
 
1. The main function of the tensioner bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy, changing sliding friction into rolling friction.
2. Bearing is an important part of contemporary machinery and equipment. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial size, vibration and noise are larger, and the price is also higher.
3. The tensioner bearing is used to tighten the loose edge. This is the tensioner bearing. Used to adjust the tightness of belts, gears, and engines.
