SB050AR0 Bearing Product Overview & Core Advantages
The SB050AR0 is a high-performance thin section angular contact ball bearing engineered for applications demanding precision and reliability. As part of the Reali-Slim Stainless Steel Bearings series, it features a single row design optimized to handle significant combined loads, including substantial thrust loads in one direction due to its defined 30° contact angle. Its compact cross-section, with a width of only 0.3125", makes it ideal for space-constrained, high-precision assemblies requiring high rigidity and corrosion resistance.
SB050AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SB050 | Indicates the specific bearing size with a 5" bore diameter. |
| A | Signifies the 30° contact angle, optimized for handling high axial loads. |
| R0 | Denotes Radial Internal Clearance of 0.0000" – 0.0005". |
SB050AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row angular contact design, combined with a 30° contact angle and a brass cage, provides exceptional stability and enables the bearing to support high combined radial and axial loads (Radial Dynamic: 976 lbf, Axial Static: 2410 lbf).
- Precision & Corrosion Resistance: Manufactured to ABEC-1 tolerance standards with rings and balls made from stainless steel, this bearing ensures consistent performance and is suitable for corrosive environments.
- Compact & Lightweight: As a Reali-Slim thin section bearing, it offers a significantly reduced cross-section without sacrificing performance, contributing to lighter and more compact overall system design (Weight: 0.37 lbs).
- Wide Operating Range: Pre-lubricated and capable of operating within a temperature range of -30°C to 110°C, ensuring reliable performance in diverse application conditions.
SB050AR0 Bearing Typical Application Areas
This bearing is ideally suited for precision machinery and systems where space, weight, and performance are critical. Key applications include:
- Robotics and Automation: Robot arm joints, rotary actuators.
- Aerospace & Defense: Guidance systems, radar platforms, and instrumentation.
- Medical Equipment: Surgical robots, MRI scanners, and diagnostic devices.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
