Technical Sourcing Guide: Deep Groove Ball Bearing

Deep Groove Ball Bearing technical specs

Technical Sourcing Guide: Deep Groove Ball Bearings (DGBB) from China

For procurement managers and specifying engineers sourcing rotating components, Deep Groove Ball Bearings represent the most widely utilized anti-friction bearing type in industrial applications—from electric motors and gearboxes to conveyor systems and agricultural machinery. When importing from Chinese manufacturing clusters (particularly in Cixi, Luoyang, and Wafangdian), technical diligence separates commodity-grade components from reliability-critical inventory.

Below are three non-negotiable technical factors requiring verification before issuing purchase orders.

1. Material & Heat Treatment (GCR15)

Material Specification Alignment
GCR15 (GB/T 18254 standard) is the Chinese high-carbon chromium bearing steel equivalent to international AISI 52100 / SAE 52100 / JIS SUJ2. While the chemical composition specifications align closely (1.30-1.65% Cr, 0.95-1.05% C), the critical differentiator lies in inclusion cleanliness y segregation control during steelmaking.

Heat Treatment Protocols
Demand documentation verifying:
Through-hardening: Austenitizing at 840±10°C followed by oil quenching
Tempering: 160-180°C to achieve hardness of HRC 61-65 (measured at raceway surface)
Dimensional stability: Sub-zero treatment (-70°C to -80°C) for precision grades (P5/P4) to prevent dimensional changes during service

Procurement Verification
– Request mill certificates (MTC) showing actual Cr/C content, oxygen index (≤12ppm for premium grades)
– Specify GCR15 for standard bearings; GCR15SiMn only for larger bore sizes (>80mm) requiring improved
