Bearing Clearance Adjustment: Why Your Bearings Fail Early

Early failure of shock absorber bearings is often related to improper bearing clearance selection. This article analyzes how clearance affects bearing lifespan.

1. What is Bearing Clearance

Bearing clearance is the gap between rolling elements and inner/outer rings: original clearance, fit clearance, and operational clearance.

2. How Clearance Affects Life

Too small clearance causes uneven load, noise, heat, poor lubrication. Too large clearance causes impact load, vibration, reduced rigidity.

3. How to Choose Proper Clearance

Consider bearing arrangement (DF/DB/DT), operating temperature, and load type. Face-to-face: C3 or C4. Back-to-back: C3.

4. Measurement Methods

Feeler gauge, lead wire, and indicator methods. Measure 3-4 points, take average. Huami provides technical guidance. Contact: 18888664498
