SB090AR0 Bearing Product Overview & Core Advantages
The SB090AR0 is a high-precision thin section angular contact ball bearing engineered for applications demanding exceptional accuracy and space optimization. Manufactured from stainless steel with a single row design, it is specifically configured to handle combined loads, efficiently supporting significant radial and axial loads simultaneously due to its 30° contact angle. Its Reali-Slim cross-section provides a high load capacity within a minimal envelope, making it ideal for compact, high-performance assemblies requiring ABEC-1 precision and reliable operation.
SB090AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SB | Indicates the series as a Stainless Steel, Thin Section Bearing. |
| 090 | Specifies the bore diameter in inches (9"). |
| A | Denotes the 30° contact angle, optimized for handling high axial loads. |
| R0 | Signifies the Radial Internal Clearance group (0.0000 – 0.0005"). |
SB090AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 30° contact angle and a brass cage, provides high rigidity and enables the bearing to support substantial combined radial and axial loads (Radial Dynamic: 1370 lbf, Axial Static: 3510 lbf).
- Precision & Stability: Manufactured to ABEC-1 tolerance standards with tight dimensional control on the bore, outside diameter, and width, ensuring smooth, precise operation and reliable positioning accuracy.
- Corrosion Resistance & Longevity: Constructed entirely from stainless steel (rings and balls), this bearing offers excellent corrosion resistance, making it suitable for harsh environments and contributing to a long service life.
- Optimized for Preload: The specified radial internal clearance allows for precise preload adjustment in application, enhancing system stiffness and rotational accuracy.
SB090AR0 Bearing Typical Application Areas
This bearing is ideally suited for precision machinery and applications where space and weight are critical constraints. Key industries and equipment include:
- Robotics (Robotic arms, joints, and actuators)
- Aerospace & Defense (Gimbals, control mechanisms, satellite components)
- Medical Equipment (Surgical robots, imaging scanners, diagnostic devices)
- Semiconductor Manufacturing (Wafer handling robots, precision stages)
- High-Precision Industrial Machinery
