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.
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.
- 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
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%.
