Pinion Seal 3104-00142 / 2402-02274 for King Long Higer Zhongtong Bus Differential Axle

These precision pinion seals are engineered specifically for King Long, Higer, and Zhongtong bus differential axles. Designed as essential rotary shaft lip seals, they provide critical protection for the differential system that manages wheel speed variations during turns and uneven road conditions.

Core Function & Protection

The primary function of these pinion seals is to maintain differential integrity by preventing lubricating oil leakage while blocking external contaminants. This dual protection safeguards internal precision gears and bearings from wear and corrosion, preventing common issues like differential noise, gear damage, and axle jamming.

Premium Construction & Materials

Manufactured to strict OEM standards using precision molding technology
Constructed from high-quality nitrile rubber (NBR) with reinforced steel skeleton
Features double-lip design: main lip for oil sealing and auxiliary lip for dust protection
Integrated self-tightening coil spring maintains consistent sealing pressure
Excellent temperature resistance from -30°C to 120°C
Superior oil resistance and wear resistance for demanding bus applications
