SG180AR0 Bearing Product Overview & Core Advantages
The SG180AR0 is a single row angular contact ball bearing from the Reali-Slim Stainless Steel series, engineered for applications requiring exceptional performance in thin-section designs. This precision bearing is specifically designed to handle significant combined loads, including high thrust loads in one direction due to its 30° contact angle. Manufactured entirely from stainless steel with a brass cage, it offers superior corrosion resistance and reliable operation. Its compact, lightweight design (1" width) combined with a high static load capacity makes it ideal for space-constrained, high-reliability applications demanding high rigidity and long service life.

| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the Reali-Slim Stainless Steel bearing series. |
| 180 | Specifies the bore diameter in inches (18.0"). |
| A | Denotes a 30° contact angle, optimized for handling high axial loads. |
| R | Signifies the use of a brass (ribbon-type) cage for strength and stability. |
| 0 | Identifies a standard radial internal clearance. |
SG180AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 30° contact angle and a robust brass cage, provides high rigidity and enables the bearing to support substantial combined radial and axial loads. It features impressive static load ratings (Radial: 36,020 lbf, Axial: 33,200 lbf) for its compact cross-section.
- Corrosion Resistance & Durability: Constructed entirely from stainless steel (rings and balls), this bearing is inherently resistant to corrosion, making it suitable for harsh environments and ensuring long-term reliability.
- Precision Performance: Manufactured to ABEC-1 precision tolerances, it ensures smooth and consistent operation, minimizing vibration and noise in precision applications.
- Optimized for Thin-Sections: As part of the Reali-Slim series, it delivers maximum load capacity within a minimal cross-section, saving weight and space in the overall assembly.
SG180AR0 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of demanding applications where a thin section, corrosion resistance, and high load capacity are critical. Key sectors include:
- Aerospace & Defense: Actuators, control mechanisms, and rotor systems.
- Semiconductor Manufacturing: Precision stages, wafer handling robots.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices.
- Robotics: Robot arm joints, precision gears, and rotary tables.
- Food & Beverage Processing: Machinery requiring frequent washdowns and corrosion resistance.
