SC080AR0 Bearing Product Overview & Core Advantages
The SC080AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding precision and reliability in a compact envelope. As part of the Reali-Slim Stainless Steel Bearings series, it excels in scenarios requiring management of combined loads. Its single row design with a 30° contact angle is optimized to handle significant axial loads in one direction while supporting radial loads, making it ideal for high-accuracy positioning systems and rotary tables where space and weight are critical constraints.
SC080AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SC | Series designation for Reali-Slim Stainless Steel Bearings. |
| 080 | Indicates a bore diameter of 8 inches. |
| A | Signifies a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the radial internal clearance group (0.0000 – 0.0005"). |
| (Open) | The bearing features an open (unsealed) design, allowing for custom lubrication schemes and minimizing torque for high-speed potential. |
SC080AR0 Bearing Structural Features & Performance Benefits
- Superior Rigidity and Load Capacity: The single row angular contact design with a 30° contact angle provides high rigidity and is specifically engineered to support substantial axial static loads (4300 lbf) and radial dynamic loads (1708 lbf) simultaneously.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with a very tight radial internal clearance, ensuring smooth, precise operation and minimal runout for high-accuracy applications.
- Corrosion Resistance and Lightweight: Constructed entirely from stainless steel (rings and balls) with a brass cage, this bearing offers excellent corrosion resistance and a low weight of 0.84 lbs, critical for aerospace and medical equipment.
- Optimized for Performance: The open design and lubricated configuration allow for optimal heat dissipation and the potential for high-speed operation, supported by a wide operating temperature range of -30°C to 110°C.
SC080AR0 Bearing Typical Application Areas
- Robotics and Automation: Precision rotary joints, robotic arms, and gearboxes where thin section bearings are essential for compact design.
- Aerospace and Defense: Gyroscopes, radar platforms, and satellite antenna positioning systems requiring high rigidity and corrosion resistance.
- Medical Equipment: CT scanners, surgical robots, and diagnostic instruments demanding smooth, precise motion and reliability.
- Semiconductor Manufacturing: Wafer handling robots and precision stages where ABEC-1 precision and cleanroom compatibility are paramount.
