SB070AR0 Bearing Product Overview & Core Advantages
The SB070AR0 is a high-precision thin section angular contact ball bearing engineered for applications demanding exceptional performance in compact spaces. Manufactured from stainless steel with a brass cage, this single-row bearing is designed to handle combined loads, supporting significant radial and axial forces simultaneously. Its defining characteristic is the 30° contact angle, which optimizes it for high rigidity and thrust capacity. As part of the Reali-Slim series, it offers a superior strength-to-cross-section ratio, making it ideal for high-reliability and precision machinery where space and weight are critical constraints.
SB070AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SB070 | Indicates the bearing series and size (7" Bore, 7.625" OD, 0.3125" Width). |
| A | Signifies the 30° contact angle, optimized for high axial load capacity and rigidity. |
| R0 | Denotes an open (unsealed) design and standard ABEC-1 precision tolerance. |
SB070AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides high resistance to combined loads. It supports a radial dynamic load of 1184 lbf and a substantial axial static load of 2980 lbf.
- Precision & Stability: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance of 0.0000 – 0.0005 inch, ensuring smooth, precise operation and minimal runout.
- Corrosion Resistance & Durability: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering excellent corrosion resistance and longevity in harsh environments.
- Compact & Lightweight: As a Reali-Slim thin section bearing, it provides maximum performance with minimal mass (only 0.5 lbs), crucial for weight-sensitive applications.
SB070AR0 Bearing Typical Application Areas
- Robotics and automation arms (for precision joint movement)
- Aerospace control mechanisms and actuation systems
- Medical Equipment such as MRI scanners and surgical robots
- Semiconductor Manufacturing equipment and precision stages
- Optical Positioning Systems and rotary tables
