|---|---|
| 308 | Standard bore diameter code (40mm) |
| SFFC | Manufacturer-specific designation indicating enhanced performance characteristics |
| Open | No seals or shields, allowing for custom lubrication solutions |
308SFFC Bearing Structural Features & Performance Benefits
Optimized Internal Design: The single row deep groove geometry provides excellent radial load capacity (10,274 lbf dynamic / 8,093 lbf static) while maintaining low friction operation. The chrome steel cage ensures reliable ball guidance and uniform load distribution.
High-Speed Capability: With a limiting speed of 8,500 rpm, this bearing is engineered for applications requiring rapid rotation. The precision-ground raceways and controlled radial internal clearance (CN) contribute to smooth high-speed performance.
Material Excellence: Constructed entirely from chrome steel (rings, balls, and cage), the bearing offers superior hardness, wear resistance, and dimensional stability across the operating temperature range of -30°C to 120°C.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with strict dimensional controls (bore: -0.012mm to 0, OD: -0.015mm to 0), ensuring consistent performance and easy installation.
308SFFC Bearing Typical Application Areas
- Electric Motors and generators requiring high-speed rotation
- Industrial Pumps and compressors handling radial loads
- Material Handling Equipment such as conveyor systems
- Agricultural Machinery components and implements
- General Industrial Machinery where reliable radial support is essential
