Thin section bearings : The size of thin section bearings is different from common rolling bearings. Its cross-sectional size is generally in the range of 120.97 -645.16mm2, and the inner diameter is generally between 25.4mm to 1m. The inner diameter of common thin section bearings can also achieve 1.3m. Thin wall bearings are the thinnest in the size series. The inner diameter or outer diameter of bearing inner and outer rings are large, and the walls are thin. Its radial dimension of cross section is less than a quarter of the inner diameter and less than twice the diameter of the rolling element.For a certain series of dimensions, the cross-sectional dimension remains constant and has nothing to do with the inner diameter. For the common ball bearing series, the radial cross-section and the ball diameter generally increase with the increase of the inner diameter. Thin wall bearings also have tighter tolerances than common large and heavy-duty bearings. Therefore, thin wall bearings ...

Single row cylindrical roller bearing single row non-outer ring cylindrical roller bearing single row non-inner ring cylindrical roller bearing double row non-outer ring cylindrical roller bearing reducer is a kind of power transmission mechanism, the speed converter of gears is used to reduce the number of gyration of the power source to the required number of gyration, and to obtain a larger Torque, in which the reducer bearing plays the role of supporting the gear shaft or connecting Rod in the rotation, because cylindrical roller bearings can be in the effective size range, the role of sustained, stable support Torque, and has a certain amount of axial movement. Nu Nj cylindrical roller bearings are often used to support the shaft at both ends, while double row eccentric bearings are used to support the gear reducer because they are not concentric, can get a smaller installation position to make reducer products to achieve a small light-weight of the role of editing reducer bearing...

sealed angular contact ball bearing can bear both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. The contact angle is the angle between the line connecting the contact point of the ball and the raceway in the radial plane and the vertical line of the bearing axis. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings can be relatively displaced along the bearing axis. This type of bearing is particularly suitable for bearing compound loads, that is, loads acting simultaneously in the radial and axial directions.

The  tractor clutch bearing  must have a certain amount of oil to lubricate when the bearing rotates, otherwise the bearing will burn Erosion and wear. If the bearing cannot be lubricated and maintained on schedule, the bearing is short of oil and it is easy to dry Working under the condition of rubbing or semi-dry friction, causing early wear, this wear is under the condition of lubrication Several times or even dozens of times, and eventually lead to damage in the long run. In addition, due to the high temperature of the engine It is transmitted to the separation bearing, and the high-speed rotation of the bearing also generates high temperature. Under this condition, the oil is very It is difficult to stay in the bearing, the bearing works continuously at high temperature, and the lubrication conditions are not good. It is also the cause of frequent damage
