SF250XP0 Bearing Product Overview & Core Advantages
The SF250XP0 is a Four Point Contact Ball Bearing designed for applications requiring exceptional load capacity in minimal space. As part of the Reali-Slim Stainless Steel Bearings series, it features an ultra-thin cross-section with a single row construction. This bearing is engineered to simultaneously support combined radial and axial loads from any direction, making it ideal for precision applications where high rigidity and compact design are critical. Its stainless steel construction provides excellent corrosion resistance for demanding environments.

| XP0 | Open construction (no seals), ABEC-1 precision class |
SF250XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: Enables the bearing to handle combined radial and axial loads in all directions with a single bearing row, providing exceptional load capacity in a compact space.
- Thin Section Construction: With only 0.75" width and minimal cross-section, this bearing maximizes space utilization while maintaining high rigidity and precision.
- Premium Material Selection: Stainless Steel rings and balls provide superior corrosion resistance, while the Brass cage ensures reliable performance at moderate speeds.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (-0.0018"– 0" bore/OD tolerance) for consistent performance in precision applications.
- Exceptional Load Ratings: Features impressive dynamic load ratings (11,909 lbf radial, 21,070 lbf axial) and static load ratings (29,060 lbf radial, 72,650 lbf axial) for its compact size.
SF250XP0 Bearing Typical Application Areas
- Robotics and Automation: Joint bearings, rotary tables, and positioning systems requiring compact design and multi-directional load capacity
- Aerospace Equipment: Control mechanisms, actuator systems, and instrumentation where corrosion resistance and reliability are critical
- Medical Equipment: Precision rotary stages, scanning devices, and diagnostic equipment requiring smooth operation and contamination control
- Semiconductor Manufacturing: Wafer handling robots, precision positioning stages, and cleanroom applications
- Military and Defense Systems: Turret systems, radar positioning, and guidance mechanisms demanding high reliability in harsh environments
