SB055XP0 Bearing Product Overview & Core Advantages
The SB055XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered with an ultra-thin cross-section, this single row bearing is designed to deliver exceptional performance in applications where space and weight are critical constraints. Its four-point contact design enables it to simultaneously support significant radial loads, axial loads in both directions, and moment loads, making it an ideal, compact solution for demanding, high-precision machinery. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable operation.
SB055XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| SB | Reali-Slim Stainless Steel Bearing Series | Indicates a thin-section, corrosion-resistant bearing family. |
| 055 | Bore Diameter (5.5 inches) | Specifies the precise inner diameter for shaft mounting. |
| XP0 | Specific internal design and tolerance class (ABEC-1) | Denotes standard precision and a pre-lubricated, open configuration. |
SB055XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single bearing to handle combined loads (radial, axial, and moment) efficiently, reducing the need for complex multi-bearing arrangements and saving valuable space.
- Thin Section & Lightweight: With a consistent cross-section and a weight of only 0.41 lbs, it minimizes system inertia and mass, which is critical for robotics and aerospace applications.
- Corrosion-Resistant Construction: The use of stainless steel for both rings and balls, combined with a brass cage, ensures long-term reliability in harsh or wash-down environments.
- Pre-Lubricated for Immediate Use: The bearing comes lubricated from the factory, facilitating easy installation and providing immediate protection against wear.
- Precision Ground to ABEC-1: Manufactured to ABEC-1 tolerance class, it offers reliable running accuracy for a wide range of industrial applications.
SB055XP0 Bearing Typical Application Areas
The SB055XP0 is ideally suited for compact, high-performance systems, including:
- Robotics: Rotary joints, actuator arms, and end-effectors where space and weight are at a premium.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms requiring corrosion resistance and reliability.
- Medical Equipment: MRI and CT scanners, surgical robots, and other precision medical devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Food & Beverage Machinery: Equipment requiring frequent wash-downs and corrosion resistance.
