Idler roller bearings in the use, often appear to be the phenomenon of damage, usually caused by the use of too long, and of course there are other reasons. In order to avoid being injured, it should be put in place the relevant work. Right, conservative and stable will response to the bearing life of the machining process. With the deterioration of metallurgical technology, the quality of the original talent lost better. The bearing is in the process of production, through a lot of cold and hot processing, in order to satisfy the small quantity, high frequency, high quality requirements, bearing steel should have good processing function. To solve the heat reaction and reject one-way thrust ball bearing quality and grinding of bearing force, and often has a more direct contact. As a result, the adoption of the stress in the shape of the demolition can be slowed down, to ensure that the demolition of the function. Loss of torque on a single holder increased by 30 to 40%, and the loss of torque of one-way thrust ball bearing increased by 50 to 65%. Manufacturer of idler roller bearing and accessories should be done normal through forging, turning, grinding and heat treatment, such as multi-channel processing of disassembly. Thin-walled bearing steel is under the use of the angle of the normal form to reach HRC61~65, the ability to make a one-way thrust ball bearings to get a higher contact fatigue strength and wear resistance.
