D155 Carrier Roller Products Details
- The carrier roller for the D155 excavator is a critical component of the undercarriage system, designed to support the weight of the track chain and prevent it from sagging. Manufactured using high-precision forging and heat-treatment processes, this roller ensures the track maintains proper tension and alignment during operation.
- Compatibility: Specifically engineered for D155 models.
- Material: High-strength alloy steel (40Mn2 or equivalent).
- Hardness: Surface hardness reaches HRC 52-60 with a depth of 4mm-8mm for maximum wear resistance.
- Sealing: High-performance mechanical seals and premium lubricants for maintenance-free operation.
Key advantages
1. Built with high-grade alloy steel and full heat treatment, offering exceptional wear and impact resistance for heavy-duty customized bulldozer parts.
2. Precision machining ensures precise fit clearance between shaft and roller body, effectively preventing oil leakage and bearing damage.
3. Robust floating seal system keeps mud, gravel and water out, protecting internal parts in harsh construction environments.
4. Fully compliant with D155 custom carrier roller standards, easy direct replacement without any adjustments.
5. Optimized roller surface reduces friction with upper track chains, extending service life and cutting maintenance expenses.
6. Strict load and durability tests conducted before delivery, ensuring reliable support during long-hour continuous operation.
