Shock absorber bearings and regular bearings look similar but differ significantly. This article details core differences to help buyers avoid mistakes.
1. Structural Differences
Regular: Standard raceway, pure radial/axial load, simple versatile design.
Shock absorber: Enhanced raceway, combined load capacity, larger rollers, with flange or special mounting.
2. Material Differences
Regular: GCr15, HRC 60-64, standard heat treatment.
Shock absorber: Vacuum degassed steel, HRC 61-65, carburizing/carbonitriding.
3. Precision Differences
Shock absorber bearings require higher precision: P5 or P4 vs P0/P6 for regular bearings.
4. Performance Requirements
Shock absorber: impact resistance, micro-slip resistance, low noise, 10-15 year life. Regular: speed-focused industrial grade.
5. How to Distinguish
Check model suffix, structure (flange), packaging label, ask professional supplier.
