6311-2RS1/W64 Bearing Product Overview & Core Advantages
The 6311-2RS1/W64 is a sealed single row deep groove ball bearing engineered for robust performance and extended service life. This metric bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions. A key advantage is its Solid Oil lubrication and integrated sealing, making it a maintenance-free solution ideal for applications requiring high reliability and protection from contamination across a wide temperature range.
6311-2RS1/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Basic bearing series, indicating a medium-duty, single row deep groove ball bearing with a 55mm bore. |
| 2RS1 | The bearing is fitted with two contact seals (one on each side) made from NBR rubber. This provides superior protection against the ingress of contaminants and the egress of lubricant. |
| W64 | This suffix indicates that the bearing is lubricated with Solid Oil, a polymer matrix saturated with oil. This technology offers long-term lubrication, resists wash-out, and is suitable for a wide operating temperature range. |
6311-2RS1/W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing offers excellent durability. With a high radial dynamic load rating of 16,096 lbf, it is designed to withstand demanding operational stresses.
- Maintenance-Free Operation: The combination of 2RS1 contact seals and W64 Solid Oil lubrication creates a sealed-for-life unit. This eliminates the need for re-lubrication, reduces maintenance costs, and ensures consistent performance in dirty or hard-to-access environments.
- Precision & Stability: Produced to ABEC 1 | ISO P0 tolerance class and standard CN radial internal clearance, it provides reliable and smooth running for a wide range of industrial applications.
- Broad Temperature Range: The Solid Oil lubrication and seal material allow for a continuous operating temperature range from -30°C to 120°C, ensuring performance in various climatic and operational conditions.
6311-2RS1/W64 Bearing Typical Application Areas
This bearing's sealed and pre-lubricated design makes it exceptionally versatile. Key application areas include:
- Electric Motors and Gearboxes
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Industrial Fans and Blowers
- Pumps and Compressors
- Various Automotive Components
