SA070AR0 Bearing Product Overview & Core Advantages
The SA070AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. Manufactured from stainless steel with a 30° contact angle, this single-row bearing is specifically designed to support combined loads, handling significant axial thrust in one direction alongside radial forces. Its Reali-Slim cross-section provides a high load capacity within an extremely compact envelope, making it an ideal solution for high-rigidity systems where weight and space are critical constraints. The bearing is pre-lubricated for immediate use and conforms to ABEC-1 precision tolerances, ensuring reliable performance in demanding operational environments.

SA070AR0 Bearing Structural Features & Performance Benefits
The performance of the SA070AR0 is derived from its meticulous construction:
- High Rigidity & Load Capacity: The single-row design with a 30° contact angle is optimized to support high combined loads. It provides a radial dynamic load rating of 823 lbf and a substantial axial static load rating of 2100 lbf, ensuring stable operation under complex loading conditions.
- Precision & Stability: Built to ABEC-1 tolerance standards with a tight radial internal clearance of 0.0000" – 0.0005", the bearing delivers smooth, precise rotation with minimal runout, which is critical for high-precision applications.
- Corrosion Resistance & Longevity: The use of stainless steel for all bearing rings and balls provides excellent corrosion resistance, making it suitable for use in harsh environments or applications requiring washdown.
- Optimized Cage Design: The brass cage ensures smooth ball guidance and stable operation, contributing to the bearing's overall reliability and service life.
SA070AR0 Bearing Typical Application Areas
The SA070AR0 is ideally suited for compact, high-performance systems across various industries, including:
- Robotics: Joint and arm articulation systems requiring high moment load capacity.
- Aerospace & Defense: Gimbals, control mechanisms, and instrumentation where weight and reliability are paramount.
- Medical Equipment: Surgical robots, scanners, and precision positioning stages.
- Semiconductor Manufacturing: Wafer handling and precision stages within cleanroom environments.
- Optical and Scanning Systems: Rotary stages and mirror mounts demanding high axial stiffness and minimal deflection.
