312SFFC1 Bearing Product Overview & Core Advantages
The 312SFFC1 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. Engineered to primarily handle radial loads, this bearing features an open design, facilitating high-speed operation and easy re-lubrication. Its construction from high-grade chrome steel ensures exceptional durability and wear resistance. With a precision ABEC 1 (ISO P0) tolerance class and standard CN radial internal clearance, it delivers reliable, consistent performance, making it an ideal choice for applications requiring a balance of cost-effectiveness and dependable operation.
312SFFC1 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 312 | Standard bore diameter series designation. |
| SFF | Manufacturer-specific series code indicating specific internal geometry and performance characteristics. |
| C1 | Indicates a special internal clearance, surface treatment, or other manufacturer-specific modification not covered by standard codes. |
| Open (No Seal) | The bearing is supplied without seals or shields, allowing for high-speed operation and custom lubrication regimes. |
312SFFC1 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open seal type and optimized internal geometry, combined with a chrome steel cage, contribute to a high limiting speed of 6,000 rpm, making it suitable for high-speed applications.
- Robust Load Capacity: With a dynamic load rating of 20,525 lbf and a static load rating of 17,535 lbf, this bearing is engineered to handle significant radial loads with high reliability.
- Precision & Stability: Manufactured to ABEC 1 precision standards with a CN clearance, it ensures smooth, low-vibration operation and consistent performance under load.
- Material Integrity: All core components—rings, balls, and cage—are made from chrome steel, providing excellent hardness, resistance to wear, and a long operational lifespan.
- Flexible Lubrication: Supplied without lubrication, it offers the flexibility for users to apply a lubricant best suited for their specific operating environment and temperature range (-30°C to 120°C).
