Rolling bearing at work, heat and wear caused by sliding friction bearing, especially under the condition of high temperature operation, the effect of inertial centrifugal force increased friction, abrasion and fever, a bracket will be caused serious burns or fracture, the bearing can work normally.
Request retainers material, therefore, besides have a certain strength, must also have good thermal conductivity, low friction coefficient, good abrasion resistance, impact toughness, density is small, and the linear expansion coefficient and roller are close to.
In addition, punching cage should be subjected to more complex stamping deformation, also requires material has good processing performance.
Usually adopt the euro, 10 or 08 a1 cold-rolled steel sheet manufacturing various types of stamping cage, its technical requirements should be accord with YB/T5059 -
The provisions of the 1993: surface quality as a group, polishing and trimming;
Dimension precision is higher accuracy;
Mechanical properties as a 'soft';
Grain size is 6 ~ 9.
Should comply with the GB/T3275 - plate technology requirements
Surface quality for 1991 regulation: 1 set;
Dimensional accuracy level;
Drawing level for Z level.
Carbon in the stainless steel belt or plate (
1 Cr18Ni9, Cr18Ni9, 3 cr13 and 4 cr13, etc. )
Punching cage, is suitable for the corrosion resistance of bearing condition of bearing steel manufacture and the environment.
