Dentail

Key Technological Advancements

Ultra-thin Ring Manufacturing
- 0.6-1.2mm wall thickness (diameter ratio <0.025) reduces weight by 52% vs. traditional bearings
- CNC precision grinding ensures raceway surface roughness Ra≤0.1μm
Modular Contact Angle System
- Standard angles α=15°/25°/40° available, axial load capacity C_a=4.2-16.8kN
- Optimized stress distribution extends contact fatigue life by 40% under P_r=12kN
Metric Precision Standard
- Full compliance with ISO 492:2018 (bore d=12-80mm, OD D=28-120mm)
- P5-class rotational accuracy (GB/T 307.1) with radial runout ≤3μm

Application

The bearings can be used in the following industries

Semiconductor: Lithography lens supports (radial runout ≤0.5μm)
Medical Imaging: MRI gradient coil rotors (30,000+ hours service life)
Precision Drives: High-speed centrifuge spindles (45,000rpm operation)
Aerospace: Micro-turbine engine bearings (-60℃~+180℃ temperature range)
