Bearing Clearance: C0 C2 C3 C4 Clearance Differences and Selection Guide

Meta Description: Learn bearing clearance C0 C2 C3 C4 differences, functions and selection methods. Choose correct bearing internal clearance from Jiangsu Huiquan Trade Co., Ltd.

Introduction

Bearing internal clearance refers to the movable gap between steel balls and bearing raceways of all bearings. Different working speeds and temperatures need matched bearing clearance: unreasonable clearance will cause bearing overheating, vibration or stuck failure.

The most common clearance grades include C0, C2, C3 and C4. Jiangsu Huiquan Trade Co., Ltd. sorts out detailed bearing clearance selection rules for global buyers.

Four Common Bearing Clearance Grades

1. C0 Normal Clearance: Standard default clearance, suitable for general normal temperature and medium-speed equipment
2. C2 Small Clearance: Small internal gap, low vibration and low noise, suitable for precision low-speed machinery
3. C3 Large Clearance: Widely used large clearance, adapt to high-speed operation and slight temperature rise
4. C4 Extra Large Clearance: Super large gap, for high temperature, high speed and heavy-load equipment

Matching Suggestion

Precision low-noise motors → C2 clearance bearings General standard machinery → C0 clearance bearings High-speed fans and motors → C3 clearance bearings High temperature heavy-load equipment → C4 clearance bearings

Conclusion

Bearing clearance is a key parameter that cannot be ignored when purchasing bearings. Tell us your equipment speed and working temperature, and Jiangsu Huiquan Trade Co., Ltd. will recommend accurate clearance grade bearings for you.
