Tensioner bearing Idler bearing
Deep groove ball bearings are very suitable for Tensioner and Idler, this kinds of bearing use in aotomotive applications
1: Tensioner is a belt tensioning device used in automobile transmission system. The tensioner is mainly composed of a fixed casing, a tensioning arm, a wheel body, a torsion spring, a rolling bearing, and a spring bushing.
2: The function of the tensioner is to adjust the tightness of the timing belt. Generally, it is replaced with the timing belt to avoid worries. Other parts do not have to be replaced. As long as regular maintenance is required. The oil must be diligent Change, generally 4,000 to 5,000 kilometers should be replaced.
3: The tensioner bearing is divided into two types: one-piece type and one-piece type. The one-piece type means that the outer iron frame is connected to the inner ring or outer ring of the bearing. Simply speaking, it is a bearing. The separate type means that the outside is an iron frame, and then the inside is pressed. A 6007 or other ordinary ball bearing.
4. Because of the harsh working environment of the tensioner, high speed, high temperature, high strength, frequent acceleration and deceleration. Therefore, the tensioner bearing must be dedicated. Especially the timing tensioner.
When selecting bearings, pay attention to the bearing clearance, use of grease, cage design, and seal ring form. These will affect the bearing quality. Then it is necessary to consider the use environment and strength of the bearing, and select the appropriate size.
The press fitting of the bearing is also the key, that is, neither too tight nor too loose. If it is too tight, it will definitely rattle or even ablate. Too loose will loosen.
Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
In order to make the bearings run well. Deep groove ball bearings, like all ball bearings and roller bearings, must bear a certain minimum load, especially at high speed or high acceleration, or when the load direction changes rapidly. Under these conditions, the inertial force of the ball and the cage and the friction in the lubricant will have an adverse effect on the rolling of the bearing, and there may be damaging sliding motion between the ball and the raceway.
