DM45 Piling Machine Track Roller 2657563041 Genuine Quality

The roller is a crucial component of belt conveyors, available in various types and quantities. It supports both the conveyor belt and material weight, accounting for 35% of total conveyor cost and generating over 70% of resistance. Roller quality is therefore essential, with options in steel and plastic construction.

• Material Selection: Manufactured from 40Mn2, 40MnB, or 50Mn steel selected based on operational requirements, ensuring base mechanical properties align with high-strength working environments.
• Manufacturing Processes: Undergoes normalizing precision forging before final heat treatment to optimize material microstructure. Follows a "welding → vertical CNC lathe precision machining" process to eliminate concentricity errors and enhance geometric accuracy.
• Heat Treatment Performance: Achieves HRC52-56 surface hardness with a hardened layer depth of ≥7-10mm (HRC45), delivering superior impact resistance, wear resistance, and fatigue resistance.
• Sealing & Lubrication System: Integrated high-performance floating seals with long-lasting lubrication system enables reliable operation in extreme temperatures (-45°C to +120°C) with zero maintenance required.
• Quality Advantages: Direct post-welding precision machining eliminates concentricity deviations, providing unmatched resistance to rapid wear and extended service life. Surface hardening and structural reinforcement design ensure uniform contact stress distribution for heavy-duty applications.
