When the rolling bearing is in operation, the bearing heat and wear are formed due to the sliding conflict; especially under high temperature working conditions; the effect of inertial centrifugal force aggravates the conflict, wear and heat; when it is severe, the cage will be burned or cracked; the bearing can not work normally. Therefore, the data of the demand cage must have a certain strength; it must also have good thermal conductivity, small conflict coefficient, good wear resistance, strong impact toughness, and density. The ants squat the stool. In addition; the stamping cage Need to taste more messy stamping deformation; also need the data to have outstanding processing functions. Generally, 08, 10 or 08A1 cold-rolled steel sheets are used to make various types of stamping cages; their skill requirements should be in accordance with the rules of YB/T5059-1993: surface quality For a group, polishing, trimming, the scale accuracy is higher precision, the mechanical function is “special soft”, the grain size is 6-9. The skill requirement of the steel plate should meet the rules of GB/T3275-1991: the surface quality is 1 group, the scale accuracy is one level, and the drawing level is Z level.
It adopts the stamping cage of medium carbon stainless steel strip or plate (1Cr18Ni9, Cr18Ni9, 3Cr13 and 4Cr13, etc.); it is suitable for the bearing working condition and environment of corrosion-resistant bearing steel.
