OEM Axis Pin Q5101255 precision‑ground for the Shacman X5000 heavy‑duty truck. This hardened Q5101255 pivot component serves as the rotating axis for suspension linkages, pedal assemblies, and mechanical control mechanisms throughout the vehicle.
Manufactured from case‑hardened alloy steel with a ground surface finish, the Axis Pin Q5101255 provides exceptional wear resistance and dimensional stability under the cyclical loading of articulated joints.
Replacing a worn or corroded axis pin with the genuine Q5101255 component restores proper joint function and eliminates the free play that causes imprecise control and accelerated bushing wear.

The Q5101255 axis pin functions as the central pivot around which two or more mechanical components rotate relative to each other. It provides a smooth, cylindrical bearing surface that supports the applied loads while allowing free angular movement.
In the Shacman X5000, axis pins are used in clutch linkage mechanisms, brake pedal pivots, throttle control connections, and suspension component hinges. Each application demands precise dimensional control for proper function.
The Axis Pin Q5101255 features a cross‑drilled hole at one end for split pin retention, ensuring that the pin remains securely in position even under the continuous vibration and cyclical loading of heavy‑duty vehicle operation.
The Q5101255 pin is manufactured from 20CrMnTi alloy steel that undergoes case hardening to create a hard, wear‑resistant surface layer while maintaining a tough, ductile core that resists impact and bending loads.
The surface hardness of HRC 58‑62 provides excellent resistance to the abrasive wear that occurs at the pin‑bushing interface. The phosphate coating provides additional corrosion protection and helps retain lubricant on the surface.
The Q5101255 axis pin is installed by aligning the bushing bores of the mating components and sliding the pin through until the head contacts the outer surface. The pin should be a close sliding fit in the bushings.
A split pin is inserted through the cross‑drilled hole and bent to secure the axis pin in position. The pin should be lubricated with the appropriate grease during assembly to ensure smooth operation and long service life.
Each production batch of Q5101255 axis pins is sampled for dimensional inspection using laser micrometers. Diameter, length, and cross‑hole position are verified against engineering specifications with micron‑level accuracy.
Hardness testing is performed on sample pins to verify both surface hardness and effective case depth. The case‑hardened layer must meet the specified thickness without excessive brittleness at the surface.
Excessive free play or a knocking sound from a pivot joint indicates that the Q5101255 pin or its mating bushings have worn beyond acceptable limits. The pin surface may show scoring, pitting, or a stepped wear pattern.
A seized or stiff joint suggests inadequate lubrication or corrosion between the pin and bushing. Disassembly, cleaning, and inspection of both components are required to determine the root cause of the binding condition.
During routine chassis inspections, pivot points should be checked for smooth operation and absence of excessive clearance. Worn pins and bushings should be replaced as a set to restore proper joint function.
The Q5101255 axis pin is dimensioned at 12 millimeters diameter by 55 millimeters length, matching the bushing sizes used in designated pivot locations throughout the Shacman X5000 chassis and control systems.
Fleet workshops should maintain these axis pins in their standard hardware inventory alongside the corresponding split pins and bushings. Having genuine components readily available supports timely repairs.
Aftermarket axis pins with incorrect hardness or dimensional tolerances can cause rapid bushing wear. We supply only the authentic Shacman X5000 Axis Pin Q5101255 manufactured to OEM specifications.
Each pin is individually protected with anti‑corrosion coating and packaged to prevent surface damage during transit. The part number Q5101255 is clearly displayed on the packaging label.
