SF200AR0 Bearing Product Overview & Core Advantages
The SF200AR0 is a thin-section angular contact ball bearing engineered for applications demanding high precision and space efficiency. This stainless steel bearing features a single-row design with a 30° contact angle, optimized to handle combined radial and axial loads simultaneously. Its inch-series construction offers a compact cross-section with a large bore relative to its outside diameter, making it ideal for high-rigidity systems where weight and space are critical constraints. Manufactured to ABEC-1 precision standards, it provides reliable performance in demanding environments.
SF200AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF200 | Indicates the Reali-Slim thin-section series with specific cross-section and size designation. |
| A | Signifies the 30° contact angle, optimized for handling significant axial loads. |
| R0 | Denotes standard radial internal clearance and an open (unsealed) construction. |
SF200AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides high stiffness and is capable of supporting substantial combined radial and axial static loads (28,100 lbf radial, 22,680 lbf axial).
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring predictable performance and ease of integration.
- Corrosion Resistance & Durability: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering excellent corrosion resistance and longevity in harsh environments.
- Space-Saving Design: As a thin-section bearing, it provides a large 20" bore within a compact 0.75" width, maximizing design flexibility in weight-sensitive and space-constrained applications.
SF200AR0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Aerospace & Defense: Gimbal systems, rotor heads, and actuation mechanisms.
- Semiconductor Manufacturing: Precision stages, wafer handling robots, and positioning equipment.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic imaging devices.
- Robotics: Robotic arms, joints, and rotary actuators requiring high moment load capacity (81,120 lbf-in static moment).
