Import bearings use and characteristics

The use of the bearing when we were in the use of bearing, the first thing to understand the characteristics of the bearing and bearing the use of the environment, if improper use and preservation, cannot give full play to the performance of the bearing, serious cause the damage of the bearing. 1. When not in use, please do not open the packing, also do not open the packaging will be placed. 2. Using the environment to keep clean. 3. To use the tools and fixture, and maintain the cleanness of clamping apparatus. Cannot be used in the production of cloth dust cloth, more can't use dirty cloth. 4. To clean the parts around, after can be configured. 1 imported bearing characteristics. Imported bearing steel, besides has the general import bearing steel performance also has the very good hardness and abrasion resistance, high temperature and contact fatigue strength, oxidation resistance and bonding resistance, dimensional stability high temperature shock resistance and high temperature. Into the imported bearing characteristics ( 1) Small and stable friction coefficient, starting easier. The general high temperature bearing f = 0. 00180. 0028, the original imported bearing f = 0. 0010. F = 0 002, needle bearing. F = 0 002, thrust ball bearing. 0018, thrust roller bearings f = 0. 002. （ 2) Radial clearance is reasonable, when bearing working at a predetermined conditions, has a good match. 3. Imported bearing structure and material: imported bearing by the inner and outer ring, rolling element and cage components. Ring and roller materials mainly is high strength, high hardness of chromium manganese high-carbon steel, cage with a soft steel plate stamping. 4. Imported bearing failure forms: is mainly caused by the contact stress fatigue pitting. The life of the bearing is calculated according to the fatigue pitting failure. To open or untight seal bearing, often appear the wear failure. Under the condition of impact load or low speed, bearing plastic deformation failure may occur.
