SA047AR0 Bearing Product Overview & Core Advantages
The SA047AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding precision and reliability in compact spaces. Manufactured from stainless steel with a 30° contact angle, this single-row bearing is optimized to handle significant combined loads, including radial and axial loads in one direction. Its Reali-Slim design offers a superior cross-section-to-diameter ratio, enabling lightweight, space-saving solutions without compromising on load capacity or rigidity. The bearing comes pre-lubricated and is rated for a wide operating temperature range, making it a robust choice for precision mechanisms.

| A | Angular Contact | Specifies the bearing type, designed to support combined radial and axial loads. |
| R0 | Radial Internal Clearance | Denotes a specific internal clearance group (0.0000" – 0.0005") for precision fit and operation. |
| (Open) | No Seal / Shield | The open construction allows for high-speed operation and custom lubrication schemes. |
SA047AR0 Bearing Structural Features & Performance Benefits
- Superior Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides excellent resistance to combined loads. It offers a high radial static load rating of 1750 lbf and an axial static load rating of 1640 lbf, ensuring stable performance under demanding conditions.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with a tightly controlled radial internal clearance, this bearing guarantees smooth, precise rotation with minimal runout, which is critical for high-precision applications.
- Durable Construction: The use of stainless steel for rings and balls, combined with a brass cage, provides excellent corrosion resistance and durability. This material selection ensures long service life even in challenging environments.
- Space-Saving Design: As part of the Reali-Slim series, this bearing features an extremely thin cross-section (0.25" width) relative to its bore diameter (4.75"), enabling compact and lightweight assembly designs.
SA047AR0 Bearing Typical Application Areas
- Precision Robotics: Ideal for robot arm joints and rotary actuators where high rigidity and compact design are paramount.
- Aerospace & Defense Systems: Used in gimbal systems, radar platforms, and guidance mechanisms requiring corrosion-resistant and high-precision bearings.
- Medical Equipment: Suitable for CT scanners, surgical robots, and other medical devices that demand smooth motion and reliable performance.
- Semiconductor Manufacturing: Applied in wafer handling and precision positioning stages where clean operation and minimal particle generation are critical.
- Optical Instrumentation: Used in rotary stages for mirrors and lenses, benefiting from the bearing's high precision and stability.
