6312-2RS1/W64 Bearing Product Overview & Core Advantages
The 6312-2RS1/W64 is a sealed single row deep groove ball bearing engineered for exceptional reliability and long service life in demanding applications. Its primary strength lies in its ability to efficiently handle radial loads while offering robust protection against contamination. A key differentiator is its Solid Oil lubrication system, which ensures consistent performance and significantly extends maintenance intervals, making it an ideal choice for applications where re-lubrication is difficult or impossible.
6312-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6312 | Basic designation: Metric, Single Row Deep Groove Ball Bearing with 60mm bore, 130mm OD, 31mm width. | Standardized dimensions for easy interchangeability and selection. |
| 2RS1 | Contact seals on both sides made of Nitrile Rubber (NBR). | Provides excellent protection against dust, dirt, and moisture ingress, retaining lubricant effectively. |
| W64 | Solid Oil lubrication. | Eliminates leakage, offers a wide operating temperature range (-30°C to +120°C), and provides a maintenance-free solution. |
6312-2RS1/W64 Bearing Structural Features & Performance Benefits
- Optimized Sealing & Lubrication: The combination of 2RS1 contact seals and W64 Solid Oil creates a highly effective, sealed-for-life system. This design prevents lubricant washout and contamination, ensuring consistent performance and a long operational lifespan without maintenance.
- Robust Load Capacity: Manufactured from high-grade Chrome Steel for both rings and balls, this bearing delivers a high radial dynamic load rating of 18,412 lbf and a radial static load rating of 11,735 lbf, providing reliable support in various load conditions.
- Precision & Stability: Built to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, it ensures smooth, low-vibration, and quiet operation, suitable for general industrial applications.
- High-Speed Capability: With a limiting speed of 5,300 rpm, it is well-suited for a wide range of high-speed machinery, supported by the low-friction properties of the Solid Oil and precision-ground components.
6312-2RS1/W64 Bearing Typical Application Areas
This versatile and maintenance-free bearing is ideally deployed in:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- Applications in food and beverage or washdown environments where sealed and lubricated-for-life components are critical.
