SC090AR0 Bearing Product Overview & Core Advantages
The SC090AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding 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 radial and axial forces simultaneously. Its Reali-Slim cross-section provides a compact and lightweight solution without compromising on load capacity, making it ideal for high-rigidity systems. The bearing comes pre-lubricated for immediate use and adheres to ABEC-1 precision tolerances, ensuring reliable operation in demanding environments.
SC090AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Significance |
|---|---|
| SC | Stainless Steel Construction (rings and balls) |
| 090 | Bore Diameter: 9 inches |
| A | 30° Contact Angle |
| R0 | Radial Internal Clearance: 0.0000 – 0.0005" |
SC090AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides excellent resistance to combined radial and axial loads, evidenced by its 1822 lbf dynamic and 5520 lbf static radial load ratings.
- Precision Performance: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance, ensuring smooth, precise rotation and minimal runout for high-accuracy applications.
- Corrosion Resistance & Durability: The use of stainless steel for both rings and balls, combined with a brass cage, offers superior corrosion resistance and longevity, suitable for a wide temperature range of -30°C to 110°C.
- Space-Saving Design: As part of the Reali-Slim series, it features a thin cross-section (0.375" width) relative to its bore diameter, enabling compact and lightweight machinery designs.
SC090AR0 Bearing Typical Application Areas
- Robotics: Rotary joints and arm actuators requiring high moment load capacity (15930 lbf-in static load moment).
- Aerospace & Defense: Gimbal systems, radar platforms, and control surfaces where precision, weight savings, and reliability are critical.
- Medical Equipment: CT scanners, surgical robots, and imaging devices demanding smooth, precise motion and corrosion resistance.
- Semiconductor Manufacturing: Wafer handling robots and precision stages that operate in clean environments.
