SF050AR0 Bearing Product Overview & Core Advantages
The SF050AR0 is a thin-section angular contact ball bearing engineered for applications requiring high precision and space optimization. As part of the Reali-Slim Stainless Steel Bearings series, it delivers exceptional performance in compact designs. This single-row bearing is specifically designed to handle combined loads, efficiently supporting both radial and significant axial loads in one direction due to its 30° contact angle. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable operation, making it ideal for high-precision applications where dimensional stability and reliability are paramount.
SF050AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| SF050 | Series designation for Reali-Slim thin-section bearings | Indicates ultra-thin cross-section for space-constrained applications |
| A | Angular Contact design | Optimized for combined radial and axial loading |
| R0 | Standard radial internal clearance | Provides optimal performance for general applications |
SF050AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: With a consistent 0.75" width across all sizes, this bearing enables compact machinery design while maintaining high load capacity. The slim profile reduces overall system weight and space requirements.
High Load Capacity: The 30° contact angle and optimized raceway geometry enable the bearing to handle substantial axial static loads up to 9460 lbf while maintaining a radial dynamic load rating of 4101 lbf. This makes it suitable for applications experiencing significant combined loading conditions.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore tolerance: -0.0010" to 0"), ensuring precise fit and smooth operation in high-precision applications.
Corrosion Resistance: Constructed entirely from stainless steel components, including rings and balls, providing excellent resistance to corrosion and enabling operation in harsh environments.
Temperature Performance: Operates effectively across a temperature range of -30°C to 110°C, making it suitable for various industrial environments.
SF050AR0 Bearing Typical Application Areas
