FAG rolling bearing structure and the commonly used materials

FAG rolling bearings to use work reliability is higher, convenient in operation and maintenance. To explain to you the following related knowledge, hope to help you. The structure of the problem a: FAG rolling bearings? And structure of the part? Answer two: FAG rolling bearings of the structure is composed of parts as follows: 1, the outer ring - — In a FAG bearing hole, is generally not 2, inner ring - — In a journal, the shaft rotational 3, rolling body - — FAG rolling bearings of the core components of 4, cage - — To separate rolling body evenly, avoid friction FAG rolling bearings structure: FAG rolling bearings are generally composed of inner ring and outer ring, rolling body, and a cage. Inner ring is installed in the shaft neck ( In the thrust FAG bearing called axial circle) With relatively tight; Outer ring is installed in the base or parts of FAG bearing hole, usually with a loose. Inner and outer ring raceway, when inside and outside the circle relative rotation, rolling body will follow the groove rolling. The role of the cage is separates rolling body evenly. In order to adapt to certain requirements, some FAG bearings can without inner ring or outer ring, or dust, sealing ring structure, etc. Question 2: what are FAG rolling bearings commonly used material? Answer two: rolling body with the inner and outer circle material requirements of the high hardness and contact fatigue strength, good abrasion resistance and impact toughness. Chromium alloy steel is commonly used in manufacturing, commonly used materials have GCr15, GCr15SiMn, GCr6, GCr9, etc. , after heat treatment the hardness of HRC61 - 65. Maintains a low carbon steel plate stamping and become, is commonly used in high-speed FAG bearing use non-ferrous metals (more Such as brass) Or plastic cage.
