SA020XP0 Bearing Product Overview & Core Advantages
The SA020XP0 is a Four Point Contact thin section bearing from the Reali-Slim Stainless Steel Bearings series. Engineered for applications demanding high precision and space-saving designs, this single-row ball bearing is characterized by its compact cross-section with a width of only 0.25". Its four point contact design enables it to simultaneously support significant combined loads, including radial, axial, and moment loads, making it an ideal solution for compact, high-rigidity assemblies. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable performance.
SA020XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SA | Indicates the bearing is part of the Stainless Steel Reali-Slim series. |
| 020 | Specifies the bore diameter of 2 inches. |
| XP | Denotes the Extra-Precision version, correlating to the ABEC-1 tolerance class. |
| 0 | Specifies the bearing cross-section (e.g., "0" for a 0.25" width in this series). |
SA020XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact & High Rigidity: The unique raceway geometry creates four points of contact between the balls and raceways under load. This design provides exceptional rigidity and enables the bearing to handle combined radial, axial, and moment loads efficiently in a single, compact unit.
- Superior Load Capacity: Engineered for high performance, it offers a dynamic load moment rating of 434 ft-lbf and a static load moment of 770 ft-lbf, ensuring reliable operation under demanding conditions.
- Precision & Smooth Operation: Built to ABEC-1 precision tolerances and featuring a brass cage, this bearing ensures smooth, low-noise, and low-vibration rotation, which is critical for high-accuracy applications.
- Corrosion Resistance & Durability: Constructed entirely from stainless steel (rings and balls), this bearing is inherently resistant to corrosion, making it suitable for harsh environments and ensuring a long service life.
SA020XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where space, weight, and precision are critical. Key industries and equipment include:
- Robotics: Joints, actuators, and rotary modules.
- Aerospace & Defense: Gimbals, control mechanisms, and satellite components.
- Medical Equipment: Surgical robots, scanners, and precision instruments.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Instrumentation Systems: Rotary tables and scanning mirrors.
