Carrier Roller for Doosan DX225LC 200105-00038

The Doosan DX225LC, a classic 22-ton extended track model, is commonly used in harsh working conditions such as heavy-duty lifting, deep trenching, steep slope operations, and mining. The extended track structure carries its own weight, placing extremely high demands on the load-bearing capacity, wear resistance, impact resistance, and sealing performance of the Carrier Roller for Doosan DX225LC 200105-00038.

Most competitors in the market use low-cost casting processes to manufacture track rollers. These rollers, subjected to repeated crushing and impact from the track chains over long periods, are prone to shell cracking, internal bearing seizure, and oil seal leakage into mud and sand. This leads to track sagging, track-beating noises, accelerated wear of the entire chassis (track chains, track rollers, drive wheels), frequent downtime for maintenance, and directly increased project operating costs.

Product Advantages

 Our entire series of Carrier Rollers for Doosan DX225LC 200105-00038 is made of 40Mn2/50Mn high-hardness boron steel, integrally forged. The internal metal texture structure is reshaped through tens of thousands of tons of forging pressure, resulting in toughness and deformation resistance far exceeding that of ordinary castings. The wheel surface undergoes a 5-8mm precision medium-frequency quenching treatment, maintaining a stable hardness of HRC52-58. This significantly enhances wear resistance and durability, making it suitable for complex operating conditions such as gravel abrasion, heavy-load impact, and mud immersion.

Internally, it features a high-load bimetallic copper bushing paired with the original factory-installed floating oil seal. High-quality grease is added at the factory, and the fully sealed oil-locking design eliminates the need for greaseing or routine maintenance for its entire lifespan. Each track roller undergoes triple quality inspection before leaving the factory: ultrasonic flaw detection, magnetic particle crack detection, and vacuum tightness testing. This thoroughly avoids hidden problems such as pinholes, microcracks, and poor sealing, ensuring long-term stable operation after installation.

The factory strictly adheres to ISO9001 quality management system and CE EU certification standards for standardized production, and publicly promises a 1-year or 2000 working hours warranty. For any quality issues such as cracking, oil leakage, or seizing caused by manufacturing processes, we support one-to-one free replacement for subsequent orders, providing stable after-sales support for global procurement customers.

FAQ

Q: Is the Carrier Roller for Doosan DX225LC 200105-00038 a perfect match for the original Doosan DX225LC excavator?

A: Yes, it is a perfect match. Strictly manufactured using CNC precision cutting according to Doosan's original engineering drawings, the installation dimensions, bolt hole spacing, and wheel surface curvature match the original parts 1:1. No modification is required; it's ready to use immediately after installation.

Q: Does it require regular greaseing maintenance after installation?

A: No. It adopts a fully enclosed, lifetime sealed lubrication structure. The lubrication is pre-locked at the factory, eliminating the need for manual grease replenishment during subsequent operations, saving you time and maintenance costs.

Q: What is the after-sales warranty policy?

A: Manufactured according to formal industrial certification standards, it enjoys a 1-year or 2000-man-hour double warranty. Any defects verified as production quality will be replaced free of charge.
