Innovative S-shaped Cage Design

3D Waveform Geometry
- Curved profile (radius R=2.5-5mm) reduces contact area by 40%, achieving friction coefficient μ=0.08-0.12
- High-strength PEEK material withstands -60℃~+200℃ and offers 5x corrosion resistance over metal cages
Dual Angular Contact Configuration
- 40° contact angle provides 18.5kN axial capacity (2.3x single-row bearings)
- Back-to-back (DB) arrangement increases moment capacity by 65% for tilting loads
Precision Grinding Process
- Raceway roughness Ra≤0.08μm, roundness error ≤1.2μm
- G2.5 dynamic balance ensures vibration ≤0.3mm/s at high speeds

Application

The bearings can be used in the following industries

Aerospace: Turbofan engine fuel pump bearings (38k RPM, 10,000h life)
Industrial Robotics: 6-axis robot wrist joints (repeatability ±0.01mm)
Medical: Da Vinci surgical robot drives (10^7 fatigue cycles)
EVs: Motor spindle bearings (80g vibration resistance)
