SB050XP0 Bearing Product Overview & Core Advantages
The SB050XP0 is a Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series, designed for applications requiring ultra-thin cross-sections without sacrificing performance. This single row bearing is engineered to simultaneously handle combined radial and axial loads from any direction, making it exceptionally versatile. Its stainless steel construction provides excellent corrosion resistance, while its compact design is ideal for space-constrained, high-precision assemblies demanding high reliability and long service life.

SB050XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows the bearing to support combined loads (radial, axial, and moment loads) efficiently in a single, compact unit, simplifying assembly and reducing weight.
- Ultra-Thin Section: With a cross-section of only 0.3125", this bearing maximizes the available space for large shafts while minimizing the overall system envelope, crucial for compact machinery design.
- Stainless Steel & Brass Construction: The use of stainless steel rings and balls provides superior corrosion resistance, while the brass cage ensures reliable operation and stability.
- High Load Capacity: Engineered for substantial dynamic and static load ratings (1236 lbf radial dynamic, 1980 lbf axial dynamic), it delivers robust performance in demanding applications.
- Precision Performance: Manufactured to ABEC-1 precision tolerances, it guarantees smooth operation, reduced vibration, and enhanced positional accuracy.
SB050XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where a large diameter shaft must be supported within a minimal space. Key industries and equipment include:
- Aerospace & Defense: Gimbals, rotor heads, and actuation systems.
- Robotics: Robotic joints, rotary actuators, and precision arms.
- Medical Equipment: MRI and CT scanners, surgical robots.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Instrumentation Systems: Rotary tables and positioning devices.
