The genuine XCMG 273100563 Sleeve is a precision‑machined wear component designed for motor grader articulation joints, blade lift linkages, and circle pivot systems. This OEM 273100563 sleeve, also known as a bushing or bearing liner, provides a low‑friction, replaceable surface that protects the parent bore from wear caused by oscillating pins.
Manufactured from high‑strength bronze alloy with a spiral lubrication groove, the XCMG 273100563 sleeve ensures consistent clearance even under extreme load cycles. Fits GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders.
Worn sleeves cause excessive play, misalignment, and accelerated pin wear. Replacing a damaged sleeve with genuine 273100563 restores original tolerances and extends the service life of your grader’s critical pivot joints.

The XCMG 273100563 sleeve is the primary wear element in all major pivot points: articulation hinge, blade lift cylinder mounts, circle drawbar connection, and steering knuckles.
It provides a replaceable bearing surface that absorbs oscillating motion and radial loads. When the sleeve wears beyond tolerance, the pin starts wearing the expensive parent bore, leading to housing replacement.
Using genuine 273100563 ensures correct hardness, internal diameter clearance, and lubrication groove geometry for optimal grease distribution and service life.
Each 273100563 sleeve is machined from continuous‑cast phosphor bronze bar, which offers superior fatigue strength and anti‑seizure properties compared to powdered metal alternatives.
The inner diameter is finish‑ground to exact tolerance after heat stabilization. Spiral oil grooves are cut using a CNC lathe with a custom tool, ensuring consistent depth and pitch that promotes grease flow along the entire pin length.
For high‑load applications, XCMG offers a steel‑backed PTFE composite version. All sleeves are 100% inspected with air gauges for roundness and taper.
To replace a worn sleeve, first remove the pin and clean the bore thoroughly. Use a sleeve puller or a press to extract the old sleeve. Do not damage the housing bore.
Lightly lubricate the outside of the new 273100563 sleeve. Press it into the housing using a mandrel that contacts only the sleeve’s end face. Ensure the grease groove aligns with the grease fitting hole in the housing.
After installation, check the inside diameter with a telescoping gauge. The pin should slide with light hand force. Grease the assembly thoroughly before operation.
Indicators include: increased play in the articulation joint (more than 3 mm measured at 1 m), squeaking or knocking noises when turning, and grease leaking past the pin seals without building pressure.
Visible scoring or galling on the pin surface also confirms a worn sleeve. Replace both the sleeve and the pin simultaneously for best results.
XCMG recommends greasing all pivot points every 100 operating hours. The sleeve’s internal grooves require a minimum of 10 pump strokes from a hand grease gun to replenish lubricant fully.
Sleeve replacement interval: 4,000‑6,000 hours for standard use, 2,500‑3,500 hours for heavy ripping or abrasive environments. Always measure pin and sleeve clearance during annual overhauls.
Using genuine XCMG 273100563 sleeves ensures consistent wall thickness and hardness. Aftermarket sleeves often have undersized OD or oversized ID, leading to rapid failure.
Every genuine XCMG 273100563 sleeve carries a 12‑month warranty against material and workmanship defects. Regional stocking hubs in Houston, Rotterdam, Dubai, and Shanghai reduce lead times.
Air freight delivery: 3‑7 business days worldwide. Emergency 24‑48 hour shipping available. Bulk orders (25+ sleeves) receive volume discounts and sea freight options.
Do not risk housing damage with cheap aftermarket sleeves. The genuine XCMG 273100563 sleeve is engineered to maintain correct clearance, resist hammering, and distribute grease efficiently. Keep a set of sleeves in your parts inventory and replace at the first sign of play.
Extend your motor grader’s joint life and reduce downtime by choosing only XCMG original sleeves. Order the 273100563 sleeve today and experience the quality that keeps your grader tight, responsive, and ready for any job condition.
