3028309 Thrust Bearing Fits Cummins Engine Crankshaft Thrust Washer Replacement Part

Product Overview

3028309 Thrust Bearing (BEARING,THRUST) is a precision sliding limit bearing specially matched for Cummins series diesel engine crankshaft assemblies. Installed between crankshaft and cylinder block, its core function is to control crankshaft axial play, bear axial thrust generated during engine operation, and reduce friction loss between crankshaft and block.

This thrust bearing effectively solves common engine faults such as crankshaft axial displacement, abnormal knocking noise, shaft surface scratch and oil pressure instability caused by wear, thinning and failure of old thrust bearings, ensuring stable crankshaft rotation and normal operation of engine power system.

Core Product Advantages

1. Multi-Layer Bimetallic Wear-Resistant Structure

   Adopts steel back + high-tin alloy friction layer composite material, strong load-bearing capacity and excellent wear resistance, withstand long-term high-load axial impact without rapid abrasion.

2. Precision Oil Groove Design

   Uniformly distributed oil storage grooves form stable lubricating oil film, effectively reduce dry friction between bearing and crankshaft, lower operating temperature and extend service life.

3. Accurate Thickness Tolerance Control

   Strict dimensional calibration ensures standard crankshaft axial clearance, prevents excessive axial movement and abnormal vibration, maintains engine running smoothness.

4. Wide Temperature Adaptability

   Stable mechanical performance under -40℃ ~ +135℃ working range, no alloy layer peeling or deformation under high-temperature engine compartment environment.

5. Anti-Corrosion Surface Treatment

   Passivation anti-oxidation layer resists erosion of engine oil and oil vapor, avoids surface corrosion and friction layer failure.

6. Standard Matching Specification

   Dimension 10cm10cm1cm, weight 0.118KG, perfectly fit Cummins engine crankshaft mounting position, plug-and-play replacement without grinding modification.

7. Strict Factory Performance Inspection

   All thrust bearings wear test, clearance detection and load pressure test, stable batch quality for engine overhaul maintenance and fleet bulk procurement.
