OEM 319004449 The XCMG Spacer 319004449 is a genuine OEM positioning component engineered to set correct axial clearance and alignment inside hydraulic and structural assemblies on XCMG excavators. Identified by part number 319004449, this precision-machined spacer delivers stable load transfer and long service life in the toughest construction, mining, and quarry environments.
Manufactured from high-strength alloy steel with a hardened and ground finish, the 319004449 Spacer offers outstanding wear resistance, dimensional stability, and corrosion protection. Its exact OEM length, bore, and face parallelism guarantee a direct replacement without modification.
By holding mating parts at the correct distance, this spacer prevents over-travel, reduces vibration, and keeps boom, arm, and bucket functions responsive through long working shifts.
The 319004449 Spacer is machined from high-strength alloy steel that resists deformation under repeated compressive load. This keeps the length stable and the faces parallel over time.
A hardened and ground surface provides excellent wear resistance against mating parts. The faces stay flat and true through millions of load cycles.
Length and bore are cut to the exact OEM profile so the spacer seats correctly and cannot shift under high pressure. Clearance control stays within specification.
The protective coating resists rust and chemical attack in coastal, mining, and high-humidity environments. The spacer stays serviceable for years.
By holding mating parts at the correct distance, the 319004449 spacer prevents over-travel and keeps cylinder response predictable across the whole machine.
Production starts with certified alloy steel bar stock that is checked for chemical composition and hardness. Each blank is cut to length before turning begins.
The spacer is turned and ground on computer-controlled machines that hold length tolerance to within 0.02 mm. Both end faces are ground parallel to within 0.01 mm.
Heat treatment brings the surface to HRC 50–56 while keeping the core tough. This combination resists wear and compression without becoming brittle.
After heat treatment, each spacer is straightened, finish-ground, and inspected. Batch records let XCMG trace every unit back to its steel heat number.
The result is a spacer that performs predictably for thousands of hours on your XCMG excavator, season after season.
Spacers set axial clearance and align components inside hydraulic and structural assemblies. Every stroke loads them through compression, friction, and heat.
The 319004449 Spacer provides dependable positioning and consistent load transfer, preventing over-travel that would reduce efficiency and accelerate wear.
Field records from heavy excavation work show that machines fitted with genuine XCMG spacers suffer fewer cylinder failures and shorter repair sessions.
The hardened surface and protective coating also resist moisture, dust, and chemical exposure, keeping performance stable across long service intervals.
Inspect spacers regularly for wear, deformation, or corrosion. Replace any compromised unit promptly with a genuine 319004449 component.
By keeping internal components aligned, this spacer supports safe, productive excavator operation every working day.
The 319004449 Spacer installs with standard hand tools, which keeps downtime and labour costs low during scheduled servicing or emergency replacement.
Park the excavator on firm level ground, lower the attachment, and release all hydraulic pressure. Lock out the machine before work begins.
Remove the assembly and dismantle it carefully. Inspect the bore and mating faces for wear or scoring. Replace any damaged parts before fitting the new spacer.
Clean all surfaces, fit the spacer and new seals, and slide the assembly into position using a suitable guide. Tighten the bolts to the specified torque.
After assembly, cycle the cylinder slowly and check for weeping at the seals. Run the machine at low idle and confirm smooth movement across the full stroke.
During routine service, inspect the spacer for wear or corrosion. Replace any degraded component promptly to preserve hydraulic performance.
Choosing the genuine 319004449 Spacer pays back over time by preventing cylinder failures, cutting diagnostic hours, and reducing unplanned downtime.
A single failed spacer can cause misalignment that damages cylinder bores, rods, and seals, turning a small repair into a major overhaul.
Across a typical 10,000-hour service life, the cylinder strokes millions of times. The hardened alloy steel of the 319004449 keeps performance consistent.
Reliable clearance control also extends the life of connected components such as rods, seals, and cylinder barrels, reducing replacement frequency.
Field data gathered from large mining and construction fleets shows genuine XCMG components cut hydraulic-related downtime by as much as 18 percent.
The durable construction and quality coating keep the spacer serviceable for years, removing the need for premature replacement.
XCMG applies sustainable manufacturing principles to the 319004449 Spacer through recyclable steel content and energy-efficient production processes.
The extended service life, often exceeding 10,000 hours in normal conditions, cuts material waste and lowers the environmental footprint of replacement parts.
Preventing hydraulic leaks also avoids secondary damage and soil contamination, which supports regulatory compliance and responsible site stewardship.
Steel and coating materials are free from restricted substances and comply with RoHS and REACH rules, ensuring safe handling and disposal.
Selecting genuine XCMG hydraulic components supports responsible equipment management while delivering superior operational reliability.
The precision-engineered design allows long, dependable service, which minimises resource consumption across the machine’s working life.
The 319004449 Spacer is held in XCMG regional distribution centres across North America, Europe, Asia, and Australia, supporting fast delivery.
Every unit is packed with rust-preventive wrapping inside a fitted carton, shielding it from impact, moisture, and contamination in transit.

Every 319004449 Spacer comes from an ISO 9001 and ISO 14001 certified plant with complete material traceability from raw steel to packed product.
Incoming steel bar stock is tested for chemical composition, hardness, and dimensional accuracy before release to the production line.
During manufacturing, length, diameter, face parallelism, and surface hardness are monitored continuously, and every finished unit receives a full visual inspection.
Post-production checks include dimensional verification, hardness testing, and surface finish measurement to confirm each spacer meets specification.
Sample spacers from each batch undergo load testing, salt spray exposure, and wear cycling to prove long-term durability and stable performance.
Only spacers that clear every quality gate are released, so you receive a dependable, high-performance hydraulic component every time.
Cheap aftermarket spacers often use lower-grade steel, inconsistent length, or inaccurate bores. Those shortcuts lead to misalignment, leakage, and poor fitment.
