2. Material Selection and Specification: What Sets Top spherical roller bearing material exporters Apart?

The material composition of spherical roller bearings directly impacts key performance attributes such as load capacity, wear resistance, anti-fatigue properties, and corrosion resistance.
Key material grades exported:

Material Grade Typical Hardness (HRC) Main Characteristics Common Certification
GR15 (AISI 52100) 60~64 High-carbon, high-chromium; superior hardness & fatigue life; excellent dimensional stability ISO 683-17, ISO 9001
Stainless Steel (9Cr18Mo) 55~60 Corrosion resistant; moderate hardness; for food/chemical applications FDA, ISO 3290
Ceramic Hybrid 70~75 Extremely high wear resistance, non-magnetic, lightweight ISO 12240
Coated Steel (PTFE/Ni-P) 58~62 Surface enhancement; reduces friction, improves corrosion resistance REACH/ROHS

Why Choose GR15 Steel?

GR15, equivalent to AISI 52100, is the gold standard for ball and roller bearing materials utilized by leading spherical roller bearing material exporters. With 1.0%C, 1.5%Cr, , it enables:

  • Extraordinary hardness post-heat treatment (up to 64HRC)
  • High anti-fatigue performance (L10 life often exceeding 100,000 hours in industrial duty)
  • Superior dimensional accuracy (tolerances within 0.005mm by CNC grinding)
  • Excellent compatibility with lubrication systems (reducing maintenance needs)
