5537423 Crankshaft Thrust Bearing Fits Cummins Engine Axial Limit Replacement Part

Product Overview

5537423 Crankshaft Thrust Bearing (BEARING,CRANKSHAFT THRUST) is a precision bimetallic limiting pad customized for Cummins series diesel engine crankshaft assemblies. Installed on the engine main bearing seat, it bears the axial thrust generated during engine operation, restricts the crankshaft from moving back and forth axially, and maintains the standard assembly clearance of the crankshaft.

This thrust bearing solves common engine failures such as crankshaft axial play, abnormal knocking noise, journal scratch and unstable oil pressure caused by thinning, abrasion and failure of old thrust bearings, which is an essential spare part for engine major overhaul.

Core Product Advantages

1. Bimetallic Composite Wear-Resistant Structure

   Steel back + high-tin alloy friction layer integrated forming, strong load-bearing capacity, withstand long-term high-load axial impact without rapid abrasion or alloy layer peeling.

2. Precision Oil Storage Groove Layout

   Uniformly distributed oil grooves form continuous lubricating oil film between bearing and crankshaft thrust surface, effectively reduce dry friction and lower operating temperature.

3. Strict Thickness Tolerance Control

   Precision machining ensures standard crankshaft axial clearance, avoids excessive displacement and vibration, keeps engine running smoothly under full load.

4. Wide Temperature Adaptability

   Stable mechanical performance within -40℃ ~ +135℃, no thermal deformation or material failure under long-term high-temperature working environment.

5. Anti-Oxidation Anti-Corrosion Surface Treatment

   Passivation anti-rust coating resists erosion of high-temperature engine oil and oil vapor, avoid surface corrosion and premature wear failure.

6. Standard Matching Installation Specification

   Dimension 21cm6.5cm10cm, weight 0.29KG, perfectly fit Cummins engine main bearing housing, plug-and-play replacement without grinding modification.

7. Strict Factory Performance Inspection

   All thrust bearings pass load pressure test, friction wear test and dimensional tolerance inspection, stable batch quality for overhaul factories and logistics fleets bulk procurement.
