Applicable Working Environments
Ideal for harsh sites with heavy impact, muddy water, and abrasive gravel. Ordinary aftermarket rollers often fail prematurely due to track sagging, abnormal vibration, shaft seizing, and seal leakage--caused by continuous friction, water erosion, and shock loads. This roller is purpose-built to resist these failure modes.
Production & Heat Treatment Process
- Integrated Forging Blank: Ensures structural integrity and impact resistance.
- Dual Heat Treatment:
- Quenching: Raises surface hardness to HRC52-58 for superior wear resistance against gravel and sediment.
- Tempering: Eliminates internal stress to prevent shell cracking under repeated impact.
- Ultra-Precision Machining: All shafts, mounting holes, and contact surfaces are CNC-machined to ±0.01mm tolerance, fully aligning with OEM standards.
Key Benefits
- Eliminates track vibration and sagging from dimensional inaccuracies
- Prevents oil leakage and shaft rust in humid, muddy conditions
- Reduces unplanned downtime caused by roller shell fracture
- Enables fast, tool-free replacement to cut maintenance time
- Extends service life by 2-3× vs. generic aftermarket rollers
Customer Case
A Southeast Asian construction company operated 12 units of PC200-5/6 fleets with generic rollers, which failed within 650-800 working hours. After switching to our OEM-spec top rollers, all units ran stably for over 1900 working hours without seal leakage or shell damage, cutting annual undercarriage maintenance costs by 35%.
Frequently Asked Questions
Q1: Does this roller fit both PC200-5 and PC200-6?
A: Yes. Part No. 20Y-30-00022 is fully compatible with both models; no gaskets or adjustments needed.
Q2: What makes it better than generic rollers?
A: Generic parts skip tempering and have tolerances over 0.05mm. Our dual heat treatment + 0.01mm precision ensures durability in harsh conditions.
Q3: Can you provide batch inspection reports?
A: Yes. We supply heat treatment test reports and dimensional inspection datasheets for all bulk orders.
