About Carrier Rollers
The carrier 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 is paramount. Available in steel construction with materials including 40Mn2, 40MnB, and 50Mn to suit various working conditions.
Our rollers undergo precision forging and normalization before complete heat treatment, achieving surface hardness of HRC52-60 with a hardened layer depth exceeding 7-10mm (HRC45). This ensures exceptional durability with high impact resistance and superior wear resistance on contact surfaces. High-quality floating seals and lubrication systems adapt to diverse climates and temperatures (-45℃ to 120℃), maintaining maintenance-free operation.
Key Features & Advantages
  • Hardening and tempering process ensures outstanding mechanical properties, exceptional strength, and enhanced resistance to wear, bending, and fracture
  • Surface hardness of HRC40-55 minimizes wear and extends operational lifespan
  • Precision engineered for accurate installation and efficient grousering
  • Capable of handling heavy loads up to 50 tons without compromising excavator performance
  • High cost-effectiveness with superior service life
