SA035AR0 Bearing Product Overview & Core Advantages
The SA035AR0 is a thin section angular contact ball bearing engineered for applications demanding 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, efficiently handling significant axial loads in one direction alongside radial loads. Its Reali-Slim cross-section provides a superior strength-to-size ratio, making it ideal for compact, weight-sensitive assemblies requiring high rigidity and reliable performance in demanding environments.
SA035AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SA | Indicates a Stainless Steel thin section angular contact bearing. |
| 035 | Specifies the bore diameter of 3.5 inches. |
| A | Denotes the 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the radial internal clearance group. |
| Open (from spec) | No seals or shields, allowing for higher possible speeds and easy re-lubrication, but requiring a clean operating environment. |
SA035AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides high rigidity and is engineered to support substantial axial static loads (1350 lbf) and radial dynamic loads (552 lbf) simultaneously.
- Precision & Smooth Operation: Built to ABEC-1 precision tolerances and featuring a brass cage, this bearing ensures smooth, quiet, and stable rotation, minimizing vibration and noise.
- Corrosion Resistance & Longevity: Constructed entirely from stainless steel (rings and balls), the SA035AR0 offers excellent corrosion resistance, enhancing its service life in harsh or wash-down environments.
- Space-Saving Design: As part of the Reali-Slim series, it provides a large bore (3.5") relative to its small cross-section (0.25" width), enabling compact and lightweight machinery designs.
SA035AR0 Bearing Typical Application Areas
This bearing is ideally suited for precision applications where space, weight, and corrosion resistance are critical. Key industries and equipment include:
- Robotics and Automation: Robot arm joints, rotary actuators, and precision gearboxes.
- Aerospace and Defense: Guidance systems, radar platforms, and satellite mechanisms.
- Medical Equipment: Surgical robots, MRI scanners, and diagnostic instrumentation.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Food and Beverage Processing: Machinery requiring frequent wash-downs and corrosion resistance.
