About Track Rollers
The roller is a critical component of belt conveyors, supporting both the conveyor belt and material weight. Accounting for 35% of total conveyor cost and generating over 70% of system resistance, roller quality significantly impacts performance.
Material & Construction
- Materials: 40Mn2, 40MnB, or 50Mn steel selected based on working conditions
- Precision forging with normalization before heat treatment
- Surface hardness HRC52-60 with hardened layer depth of 7-10mm (HRC45)
- High-quality floating seals and lubrication system for -45℃ to 120℃ operation
Key Features
- Quench-tempering process for superior mechanical properties and wear resistance
- Surface hardness HRC40-55 reduces wear and extends service life
- Precision engineered components with lifetime sealing system
- Forged shells resist bell mouthing deformation
