SF400XP0 Bearing Product Overview & Core Advantages
The Reali-Slim Stainless Steel Bearing represents a specialized class of thin section bearings engineered for applications demanding compact design and high performance. This Four Point Contact ball bearing is constructed from corrosion-resistant stainless steel and is pre-lubricated for immediate use. Its primary advantage lies in its ability to support significant combined loads—simultaneously handling radial loads and high axial loads in both directions—within an extremely slim cross-section, making it ideal for saving space and weight in precision machinery.
SF400XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Designation | Technical Significance |
|---|---|---|
| Series | Reali-Slim | Indicates a thin section bearing with a standardized, slim cross-section. |
| Material | Stainless Steel | Provides excellent corrosion resistance for harsh environments. |
| Contact Type | Four Point Contact | Enables the bearing to support combined radial and axial loads from any direction with a single row of balls. |
| Seal Type | Open | Designed for applications where external sealing is provided, allowing for higher possible speeds. |
| Tolerance Class | ABEC-1 | Specifies a standard level of precision for running accuracy. |
SF400XP0 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its unique thin section design and Four Point Contact geometry.
- High Load Capacity in a Compact Design: The Four Point Contact raceway allows a single bearing to replace a complex combination of radial and thrust bearings, supporting substantial axial static load ratings of 115,000 lbf and radial dynamic load ratings of 15,034 lbf, all within a minimal cross-section.
- Combined Load Handling: This design is exceptionally effective at managing combined loads and overturning moments, with a rated load moment of 229 ft-lbf, providing high rigidity and stability.
- Corrosion Resistance & Longevity: Manufactured entirely from stainless steel (rings and balls) with a brass cage, the bearing is inherently resistant to rust and corrosion, ensuring reliability in challenging conditions and a wide temperature range of -30°C to 110°C.
- Pre-Lubricated for Immediate Service: The bearing comes lubricated from the factory, reducing assembly time and ensuring optimal initial performance.
