Wheel Bearing Types Comparison

7-Point Inspection Checklist

1. ABEC-3 precision rating
2. Double lip seals
3. SAE J2550 compliance

Technical Analysis

Premium bearings maintain 0.0002"-0.0004" radial clearance (Fig.1). When diagnosing noise, measure axial play: >0.005" indicates replacement need. Leading manufacturers like SKF require Rockwell C58-64 hardness.

Market Trends

Europe holds 38% market share (Statista), while ASEAN demand grows at 7.2% CAGR. New EU Regulation No 2023/814 mandates 30% recycled steel content.

FAQ

Are ceramic bearings street-legal?

DOT-compliant variants exist but require FMVSS 121 certification. Always verify bearing ID codes through NHTSA's VIN decoder.
