SB140AR0 Bearing Product Overview & Core Advantages
The SB140AR0 is a thin section angular contact ball bearing engineered for applications demanding high precision and space optimization. As part of the Reali-Slim Stainless Steel series, this bearing features a single row design with a 30° contact angle, enabling it to support significant combined loads—simultaneously handling radial loads and thrust loads in one direction. Its stainless steel construction provides excellent corrosion resistance, making it ideal for challenging environments. The bearing's compact cross-section (0.3125" width) allows for lightweight, streamlined assemblies without sacrificing performance or load capacity.
SB140AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SB140 | Indicates a thin section bearing series with a 14" bore diameter. |
| A | Signifies Angular Contact design with a 30° contact angle for handling combined loads. |
| R0 | Denotes Open (unsealed) construction and standard ABEC-1 precision tolerance. |
SB140AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 30° contact angle and stainless steel components, provides high rigidity and excellent capacity for combined radial and axial loads (Radial Dynamic Load: 1767 lbf, Axial Static Load: 4670 lbf).
- Precision & Stability: Manufactured to ABEC-1 tolerance standards with a tight radial internal clearance (0.0000 – 0.0005"), ensuring smooth operation and precise rotational accuracy in high-performance applications.
- Corrosion Resistance & Durability: The use of stainless steel for both rings and balls, along with a brass cage, offers superior corrosion resistance and reliable performance within a wide temperature range of -30°C to 110°C.
- Space-Saving Design: As a Reali-Slim thin section bearing, it minimizes weight and cross-sectional space (Width: 0.3125") while maintaining high static load moment capacity (19,500 lbf), ideal for compact machinery designs.
SB140AR0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, rotor heads, and actuation mechanisms where lightweight and corrosion-resistant components are critical.
- Robotics & Automation: Robotic arm joints, precision stages, and rotary tables requiring high rigidity and angular contact performance.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices demanding precision, cleanliness, and reliable operation.
- Semiconductor Manufacturing: Wafer handling robots and precision positioning systems where thin section bearings and stainless steel construction are essential.
