SC250AR0 Bearing Product Overview & Core Advantages
The SC250AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space optimization. Manufactured from stainless steel with a brass cage, this single-row bearing is designed to handle significant combined loads, particularly excelling under high axial loads due to its 30° contact angle. Its compact design, with a minimal cross-section relative to its bore diameter, makes it an ideal solution for high-rigidity and weight-sensitive systems operating within a wide temperature range.
SC250AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SC | Indicates the Reali-Slim thin-section bearing series. |
| 250 | Specifies the bore diameter of 25.0 inches. |
| A | Denotes the 30° contact angle, optimized for high axial load capacity. |
| R0 | Signifies an open (unsealed) design and standard ABEC-1 precision tolerance. |
SC250AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides exceptional resistance to combined radial and axial loads. It offers a high axial static load rating of 9010 lbf, making it suitable for applications with significant thrust forces.
- Precision & Stability: Manufactured to ABEC-1 tolerance class with a tight radial internal clearance, this bearing ensures smooth, precise rotation and minimal runout for accurate positioning.
- Corrosion Resistance & Durability: Constructed entirely from stainless steel components, the bearing provides excellent corrosion resistance, enhancing its service life in harsh environments. The brass cage ensures reliable performance under high-speed and high-load conditions.
- Space-Saving Design: As a thin-section bearing, it offers a large bore diameter relative to its cross-section, enabling compact and lightweight machine designs without sacrificing performance.
SC250AR0 Bearing Typical Application Areas
This bearing is ideally suited for precision machinery and systems where space, weight, and high axial load capacity are critical. Key applications include:
- Robotics and Automation arms and joints
- Aerospace control mechanisms and actuation systems
- Medical Equipment such as MRI scanners and surgical robots
- Semiconductor Manufacturing equipment
- Precision Rotary Tables and indexing heads
