SC055AR0 Bearing Product Overview & Core Advantages
The SC055AR0 is a high-precision Angular Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings family, designed for applications demanding a compact cross-section and high performance. This single row bearing excels in handling combined loads, efficiently managing both radial loads and substantial thrust loads in one direction due to its specified 30° contact angle. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable operation. Its ABEC-1 precision tolerance and optimized internal geometry ensure smooth, high-speed operation, making it an ideal component for space-constrained, high-rigidity systems.
SC055AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SC | Indicates the bearing series, specifically the Reali-Slim thin-section series. |
| 055 | Specifies the nominal bore diameter in inches (5.5"). |
| A | Denotes the 30° contact angle, optimized for handling high axial loads. |
| R0 | Specifies the internal clearance group (Radial internal clearance: 0.0000 – 0.0005"). |
SC055AR0 Bearing Structural Features & Performance Benefits
- Thin-Section Design & High Rigidity: The Reali-Slim construction provides a minimal cross-section (Width: 0.375") without sacrificing structural integrity, enabling compact and lightweight assemblies while maintaining high rigidity.
- Superior Load Capacity: The 30° contact angle and optimized raceway geometry allow the bearing to support significant combined loads, with a radial dynamic load rating of 1374 lbf and a high axial static load rating of 3370 lbf.
- Precision & High-Speed Capability: Built to ABEC-1 tolerance standards with tight dimensional control (Bore/Outside diameter tolerance: -0.0010"– 0") and a brass cage for stability, ensuring smooth operation and suitability for high-speed applications.
- Corrosion Resistance & Durability: The use of stainless steel for both rings and balls provides excellent resistance to corrosion, making it suitable for harsh environments and extending service life.
- Pre-lubricated for Immediate Use: The bearing comes lubricated from the factory, ready for installation and initial operation within its specified temperature range of -30°C to 110°C.
