| XP | Cross-section series designation |
| 0 | Open (unsealed) construction |
SG400XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: Enables the bearing to support significant moment loads (374 ft-lbf rated) while accommodating combined radial and axial forces, effectively replacing more complex bearing arrangements.
- Thin-Section Construction: The compact 1" width and minimal cross-section maximize space efficiency without compromising load capacity, featuring precise bearing dimensions (40" bore, 42" OD).
- Premium Material Selection: Stainless steel rings and balls provide superior corrosion resistance, while the brass cage ensures stable operation and extended service life.
- High Load Capacity: Exceptional dynamic load moment rating of 374,256 lbf and axial static load capacity of 168,300 lbf make it suitable for rigorous applications.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance (0.0000 – 0.0005") for consistent performance.
SG400XP0 Bearing Typical Application Areas
- Robotics & Automation: Rotary joints, robotic arms, and positioning tables requiring high moment load capacity.
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Medical Equipment: CT scanners, MRI systems, and surgical robotics where precision and reliability are critical.
- Industrial Machinery: Rotary tables, indexing heads, and precision turntables in manufacturing equipment.
- Semiconductor Manufacturing: Wafer handling robots and precision positioning stages.
