Tapered Roller Bearing 31311 810W93420-0097 Sinotruk Sitrak

Product Introduction

This kit combines a high-performance tapered roller bearing with a precision adjusting ring, designed to support radial and axial loads in the rear wheel hub while allowing technicians to set optimal bearing preload for long service life.

Structure & Material

• Material:

• Bearing: High-carbon chromium bearing steel, heat-treated for hardness and fatigue resistance.

• Adjusting Ring: High-strength alloy steel, precision-machined for accurate preload adjustment.

  • Design: A single-row tapered roller bearing (with cone and cup) paired with a flat adjusting ring. The tapered geometry efficiently handles both radial and axial loads, while the ring fine-tunes bearing preload.

Performance

• Dual Load Handling: Tapered design supports heavy radial loads and axial thrust from braking and cornering.

• Precision Preload Adjustment: The adjusting ring enables technicians to set optimal bearing preload, reducing wear and extending component life.

• Low Friction: Precision-machined components minimize friction and heat buildup during operation.

Durability

• Bearing steel resists fatigue and wear under continuous heavy-duty operation.

• Alloy steel adjusting ring maintains dimensional stability for consistent preload over time.

Core Function

1. Wheel Hub Support: Bears radial and axial loads from the rear wheel hub.

2. Preload Adjustment: Enables precise setting of bearing preload to optimize performance and durability.

3. Load Distribution: Efficiently transfers forces to the axle/hub assembly.
