Overview
ThePSI20 Series Four-Point Contact Slewing Bearings with Internal Gear Teeth represent a breakthrough in rotational bearing technology, combining advanced load distribution principles with optimized gear integration. Designed for heavy-duty industrial applications, these bearings deliver exceptional performance in complex loading scenarios while maintaining precise rotational control.
Key Technical Features
- Optimized Raceway Geometry: Features a 45° contact angle for balanced axial, radial, and moment load distribution
- High-Density Load Paths: Maintains contact at four distinct points during rotation, reducing stress concentration
- Dynamic Load Capacity: 32% higher than standard single-row ball bearings in comparable sizes
2. Integrated Internal Gear System
- Precision Gear Manufacturing: AGMA Class 9 accuracy standard (DIN 3965 equivalent)
- Modular Integration: 20° pressure angle gears with module ranges from 4 to 12
- Surface Hardening: 58-62 HRC case-hardened teeth with ground finishing
3. Advanced Material Composition
- B4 alloy steel (DIN 1.7225)
- Rolling elements: 100Cr6 bearing steel (DIN 1.3505)
- Customizable surface treatments:
- Salt bath nitrocarburizing (QPQ)
- Zinc-nickel electroplating
- Ceramic-based composite coatings
