Technical Sourcing Guide: Self-Aligning Roller Bearing

Self-Aligning Roller Bearing technical specs

Technical Sourcing Guide: Self-Aligning Roller Bearings (Spherical Roller Bearings) from China

Target Applications: Heavy machinery, mining equipment, steel mill gearboxes, vibrating screens, wind turbines, and pulp/paper machinery where shaft deflection and misalignment are operational realities.

When sourcing self-aligning roller bearings (Spherical Roller Bearings – SRBs) from Chinese manufacturers, the variance in metallurgical consistency and processing precision between Tier-1 OEM suppliers and generic trading houses is substantial. This guide addresses the three technical pillars that determine service life and operational reliability in heavy-industrial environments.


Material & Heat Treatment (GCr15)

Material Specification & Equivalency
Chinese manufacturers predominantly utilize GCr15 (GB/T 18254 standard) for rings and rolling elements, the Chinese equivalent of AISI 52100 bearing steel. For procurement managers, verification points include:

  • Chemical Composition Verification: Demand mill certificates showing Cr content 1.30-1.65%, C content 0.95-1.05%. Substandard suppliers often use GCr15SiMn or recycled bearing steel, compromising fatigue life.
  • Hardness Standards: After heat treatment, rings must achieve 58-64 HRC on the raceway surface. Request Rockwell hardness test reports; values below 58 HRC indicate insufficient martensitic transformation and premature spalling risk.
  • Heat Treatment Protocol: Insist on through-hardening (quenching and tempering) rather than induction hardening for the raceways. Through-h
