SF090AR0 Bearing Product Overview & Core Advantages
The SF090AR0 is a stainless steel thin-section angular contact ball bearing designed for applications requiring high precision and corrosion resistance. As part of the Reali-Slim series, it features a single-row design with a 30° contact angle, enabling it to effectively handle combined loads—significant radial loads alongside substantial thrust loads in one direction. Its inch-dimension construction (9" bore × 10.5" OD × 0.75" width) provides an optimal solution for space-constrained assemblies while maintaining high rigidity and operational stability. Manufactured to ABEC-1 precision standards with stainless steel components and brass cage, this bearing delivers reliable performance in demanding environments.
SF090AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF090 | Reali-Slim series thin-section bearing with 9" bore diameter |
| A | 30° contact angle design for combined load capacity |
| R0 | Standard radial internal clearance (0.0000-0.0005") |
SF090AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The bearing's compact cross-section (0.75" width) maximizes space utilization while maintaining structural integrity, making it ideal for weight-sensitive applications.
Superior Load Capacity: The 30° contact angle enables efficient handling of combined radial and axial loads, with impressive static load ratings of 13,190 lbf radial and 13,700 lbf axial.
Corrosion-Resistant Construction: Manufactured entirely from stainless steel (rings and balls) with a brass cage, this bearing offers excellent corrosion resistance and is suitable for harsh environments.
Precision Performance: Built to ABEC-1 tolerance standards with tight dimensional control (±0.0012" on diameters), ensuring smooth operation and precise positioning in demanding applications.
Temperature Compatibility: Operating temperature range of -30°C to 110°C allows for use in various environmental conditions while maintaining dimensional stability.
