Tapered Roller Bearing AZ400741710005 Sinotruk Sitrak

Product Introduction

This sealed tapered roller bearing is a critical component for heavy-duty truck clutch and axle systems, designed to handle both radial forces and axial thrust while protecting against contamination for long, maintenance-free operation.

Structure & Material

• Material: High-carbon chromium bearing steel (GCr15), heat-treated for hardness, wear resistance, and fatigue strength. The integrated seal uses nitrile rubber (NBR) for oil resistance.

• Design: A single-row tapered roller bearing with an integrated sealing system (marked by the green indicator). The tapered geometry efficiently supports combined radial and axial loads, while the seal blocks dirt and retains lubrication.

Performance

• Combined Load Handling: The tapered design efficiently supports both heavy radial loads and significant axial thrust, ideal for clutch release and axle applications.

• Contamination Protection: The integrated seal prevents dirt, water, and debris from entering, ensuring consistent lubrication and reducing maintenance needs.

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

Durability

• Bearing steel resists pitting, spalling, and deformation under continuous heavy loads and shock impacts.

• The sealed design maintains lubrication integrity, extending service life in harsh operating environments.

Core Function

1. Load Support: Bears combined radial and axial loads in clutch release or axle assemblies.

2. Contamination Resistance: Sealed design protects internal components and retains lubrication.

3. Smooth Operation: Enables low-friction rotation for clutch engagement/disengagement or axle rotation.
