Steel Rollers

Heavy-Duty Steel Rollers for Bearings, Conveyors & Precision Machinery

Steel rollers are robust cylindrical components designed for demanding applications requiring exceptional wear resistance and load capacity. Manufactured primarily in chrome steel (UNI 100Cr6), they are widely used in roller bearings, industrial conveyors, and precision engineering systems.

Atlas Ball & Bearing supplies high-quality steel rollers that deliver outstanding durability and consistent performance under extreme mechanical stress. Whether you need stainless steel rollers for corrosion resistance or heavy-duty steel rollers for high-load environments, we provide the right solution.

Steel Rollers

Available Grades and Hardness

Our standard steel rollers are produced in:

  • Chrome Steel (UNI 100Cr6) – The go-to material for high-load applications and precision components

  • Tool Steel (AISI S2, M2) – Offers exceptional toughness and impact resistance

Standard Hardness

Our steel rollers are heat-treated to achieve hardness levels between 58–65 HRC (653 – 832 Hv10). This hardness ensures:

  • Excellent wear resistance

  • High load-bearing performance

  • Long-term structural integrity
