Doosan DX200A DX200LC Top Roller, OEM Replacement Part 200105-00025
Product Overview

This top roller is a standard OEM replacement part for Doosan DX200A and DX200LC excavators, marked with part number 200105-00025. It matches original installation sizes completely and requires no secondary processing during assembly. The component is manufactured to adapt to long-term heavy-duty operation and common onsite working conditions.

Product Specification
Item Specification
OEM Part Number 200105-00025
Applicable Models Doosan DX200A / DX200LC
Machining Tolerance ±0.01mm CNC precision processing
Heat Treatment Integral quenching + stress relief tempering
Application Sites Quarry, muddy construction site, road work, rough terrain
Installation 1:1 OEM direct replacement
Applicable Working Environments

This roller is suitable for sites with heavy load, muddy water, gravel, and frequent impact. Long-term friction from abrasive particles, water erosion, and continuous impact can cause ordinary rollers to develop track sagging, abnormal vibration, shaft jamming, and seal leakage.

Production & Heat Treatment Process

All products use integrated forging blanks. Quenching improves surface hardness for anti-wear performance. Tempering eliminates internal stress to prevent shell cracking under repeated impact. Key assembly surfaces, holes, and shafts are finished by CNC machines, with machining error kept within 0.01mm, consistent with OEM standards.

Improved Performance
  • Resolve track vibration caused by dimensional deviation
  • Stop oil leakage and shaft rust in wet and muddy environments
  • Reduce unplanned downtime due to component damage
  • Support fast installation to shorten maintenance hours
Customer Case

A local machinery service company uses a fleet of Doosan DX200A and DX200LC excavators. Conventional aftermarket rollers failed within 700 to 820 working hours. After switching to our products, the rollers operate stably for over 1800 working hours, cutting annual maintenance costs by 34%.

Frequently Asked Questions
Q1: Can this part fit both DX200A and DX200LC?
Yes. Part No. 200105-00025 is compatible with both models, no modification required.
Q2: What is the difference between this part and generic products?
Generic parts normally omit tempering process and have tolerance over 0.05mm. Our complete heat treatment and 0.01mm precision ensure stable performance in harsh working conditions.
Q3: Can you provide inspection reports for bulk orders?
Yes. Heat treatment and dimensional inspection reports are available for batch shipments.
