SB025XP0 Bearing Product Overview & Core Advantages
The SB025XP0 is a Four Point Contact thin section bearing from the Reali-Slim Stainless Steel series. Engineered for applications requiring compact design and high precision, this single row ball bearing is capable of supporting combined radial and axial loads from any direction. Its all-stainless-steel construction and ABEC-1 precision make it ideal for high-reliability, corrosive environments where space and weight are critical constraints.

SB025XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows a single bearing row to efficiently handle combined loads (radial, axial, and moment loads) simultaneously, simplifying assembly and reducing envelope size.
- Thin Section & Lightweight: With a consistent cross-section (0.3125" width), this bearing minimizes weight (0.19 lbs) and space requirements without sacrificing performance, a key advantage in compact machinery.
- All-Stainless-Steel Construction: Both rings and balls are made from stainless steel, providing excellent corrosion resistance and making the bearing suitable for harsh environments, including washdown or medical applications.
- High Load Capacity: The design delivers a high axial static load rating of 2840 lbf and a dynamic load moment of 895 ft-lbf, ensuring reliable performance under significant stresses.
- Precision & Stability: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance, the bearing offers smooth, precise operation and consistent running accuracy.
SB025XP0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Robotics and Automation (e.g., robotic arms, rotary joints)
- Aerospace & Defense systems (e.g., gimbals, control mechanisms)
- Medical Equipment (e.g., MRI scanners, surgical robots)
- Semiconductor Manufacturing equipment
- Precision Rotary Tables and Indexing Heads
