Deep groove ball bearings for TM series automotive gearboxes
The deep groove ball bearing for automobile gearbox works in the oil mist environment formed by the lubricating oil in the gearbox, and the metal impurities such as the gear wear iron scrap contained in the lubricating oil will enter the inside of the bearing, which is easy to cause the external starting point of the raceway to peel off. At the same time, because the gearbox mainly transmits by helical gears, helical gears and other forms of gears, the bearings must be able to withstand large axial loads as well as impact loads.
For the actual situation, this product adopts the design method of ultimate load, and adopts special raw materials, heat treatment methods, sealing structure, etc., which satisfies the needs of working conditions. This kind of product is distinguished by "TM" before the code name.
