Shock Absorber Bearings vs Regular Bearings: Don't Buy the Wrong Ones

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.
