6312-2RS1/C3W64 Bearing Product Overview & Core Advantages
The 6312-2RS1/C3W64 is a single row deep groove ball bearing engineered for high reliability and robust performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering a degree of axial load capacity in both directions. The bearing features integrated seals (2RS1) and is pre-lubricated with Soild Oil (W64), making it a virtually maintenance-free solution. With a C3 radial internal clearance, it is well-suited for applications involving thermal expansion or where interference fits are used, ensuring stable operation and a long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6312 | Basic bearing series and size designation (60mm bore, 130mm OD, 31mm width). |
| 2RS1 | Contact rubber seals on both sides, providing excellent protection against contamination and moisture ingress. |
| C3 | Greater than normal radial internal clearance, ideal for applications with shaft expansion or heavy interference fits. |
| W64 | Pre-lubricated with Soild Oil, a polymer-based lubricant that does not leak, offering long-term lubrication and eliminating re-lubrication needs. |
6312-2RS1/C3W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing offers high strength and durability. With a dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, it is designed to handle significant radial loads in continuous operation.
- Sealed & Lubricated for Life: The double-sided contact seals (2RS1) effectively retain the Soild Oil lubricant and exclude contaminants. This combination provides a maintenance-free solution, reducing downtime and total cost of ownership.
- Optimized for Thermal & Fit Conditions: The C3 clearance provides operational stability in applications where temperature fluctuations or press-fits cause a reduction in the internal bearing clearance, preventing premature failure due to overheating or brinelling.
- Wide Operating Temperature Range: The bearing is capable of operating in temperatures from -30°C to 120°C, making it suitable for a broad spectrum of industrial environments.
