6311-2RS1/C3W64 Bearing Product Overview & Core Advantages
The 6311-2RS1/C3W64 is a sealed single row deep groove ball bearing engineered for superior performance in demanding industrial applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a high degree of operational reliability, long service life due to its Solid Oil lubrication (W64), and the ability to operate effectively under conditions requiring a C3 radial internal clearance. The combination of sealed construction and premium chrome steel components makes it an ideal choice for applications where contamination protection and consistent performance are critical.
6311-2RS1/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Basic bearing designation indicating a single row deep groove ball bearing with a 55 mm bore, 120 mm OD, and 29 mm width. |
| 2RS1 | The bearing is fitted with two contact seals (one on each side), providing excellent protection against contaminants and moisture ingress. |
| C3 | Specifies a greater than normal radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. |
| W64 | Indicates the bearing is pre-lubricated with Solid Oil, a polymer-based lubricant that is resistant to washout and provides long-term, maintenance-free operation. |
6311-2RS1/C3W64 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals effectively shield the internal components from dust, dirt, and moisture, significantly enhancing bearing life in contaminated environments.
- Optimized Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing achieves a high radial dynamic load rating of 16,096 lbf and a radial static load rating of 10,116 lbf, ensuring reliable performance under significant loads.
- Maintenance-Free Operation: The integrated Solid Oil (W64) lubrication eliminates the need for re-lubrication, reduces friction, and is effective across a wide temperature range from -30°C to 120°C.
- Stable High-Speed Performance: With a limiting speed of 5,600 rpm and an ABEC 1 (ISO P0) tolerance class, it offers smooth and precise operation suitable for a variety of industrial machinery.
