312SFF Bearing Product Overview & Core Advantages
The 312SFF is a single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity and precision operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and dimensional stability. Its open design allows for versatile lubrication options, while the robust construction using chrome steel for all core components ensures durability and a long service life, making it an ideal choice for general industrial machinery.
312SFF Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 312 | Standard metric series designation, indicating a medium bore size. |
| SFF | Manufacturer-specific designation. Consult factory datasheet for exact specifications related to internal design or performance enhancements. |
| N/A (Open) | No seals or shields, allowing for high-speed operation and custom lubrication. |
| N/A (CN Clearance) | Standard radial internal clearance for normal operating conditions. |
312SFF Bearing Structural Features & Performance Benefits
- High Load Capacity: Engineered with a deep groove raceway, this bearing efficiently supports significant radial loads (Dynamic: 20,525 lbf, Static: 17,535 lbf), making it suitable for demanding applications.
- Precision & Stability: Built to ABEC 1 precision class with tight dimensional tolerances on the bore diameter (60mm) and outside diameter (130mm), ensuring smooth and accurate rotation.
- Versatile Speed Performance: The open design and chrome steel cage contribute to a high limiting speed of 6,000 rpm, accommodating a wide range of operational requirements.
- Robust Construction: The use of chrome steel for the rings, balls, and cage provides excellent resistance to wear and fatigue, enhancing the bearing's longevity and reliability.
- Flexible Lubrication: The unsealed construction allows for the application of specialized lubricants to optimize performance for specific temperature ranges (-30°C to 120°C) and operating environments.
