Introduction

This Wheel Seal 90003074387 is a high-quality OEM waterproof and oil-proof component specially designed for SINOTRUK heavy-duty trucks, including HOWO series tractors, dump trucks and cargo trucks. It is professionally installed on the front and rear wheel hub assemblies, serving as a key protective sealing part for the wheel axle system.

The wheel seal plays two core protective roles: it locks the internal lubricating grease of the wheel hub to prevent oil leakage, and effectively blocks external dust, muddy water, sand and sediment from invading the hub bearing and axle core. It avoids bearing dry friction, overheating damage, axle wear and wheel jamming faults caused by oil loss and dirt ingress. Made of high-elasticity oil-resistant rubber and rigid metal framework, it features excellent aging resistance and tight fitting performance, adapting to long-term heavy-load driving, bumpy mine roads and all-weather complex working environments. It is a essential fast-wearing aftermarket spare part for global SINOTRUK heavy truck fleets.

Key Features

✅️Precise OEM Standard 90003074387

Strictly compliant with original factory size, inner and outer diameter tolerance and installation radian. Perfect matching for SINOTRUK HOWO wheel hub position, realizing direct plug-and-play replacement without modification, no gap after installation.

✅️Dual-Layer Metal & Rubber Integrated Structure

Adopts high-hardness metal outer frame + high-toughness oil-resistant rubber inner layer. The overall structure is firm and not easy to deform, maintaining stable sealing pressure during wheel high-speed rotation and heavy-load vibration.

✅️Zero Oil Leakage & Grease Locking Performance

Precise lip sealing design closely fits the axle shaft surface, effectively locking hub lubricating grease, preventing grease overflow and loss, ensuring sufficient lubrication of hub bearings for a long time.

✅️Super Dustproof & Waterproof Protection

Isolates external muddy water, dust, gravel and humid air thoroughly, prevents bearing rust, abrasion and axle core corrosion, greatly reducing the failure rate of wheel hub assembly.

✅️Excellent Aging & Wear Resistance

Adopts upgraded industrial rubber material, resistant to high temperature, low temperature and long-term friction. It does not harden, crack or deform after long-term operation, with ultra-long service life.

✅️Avoid Costly Wheel System Failures

Effectively prevent common faults such as hub heating, bearing burning, wheel shaking and running deviation caused by seal failure, reducing fleet maintenance costs and downtime loss.

✅️Universal Hot-Selling Aftermarket Part

Standard stocking wearable part for truck repair shops, spare parts wholesalers and fleet maintenance stations, with stable repeat orders in Central Asia, Africa and Southeast Asian heavy truck markets.
