6318-2RS1/C3W64 Bearing Product Overview & Core Advantages
The 6318-2RS1/C3W64 is a single row deep groove ball bearing engineered for high-performance industrial applications. This sealed bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a robust C3 radial internal clearance for thermal expansion management in demanding operations, and integrated Solid Oil lubrication (W64) for long-term, maintenance-free service. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable precision and is ideal for applications requiring consistent performance and high reliability.
Model Code Breakdown
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2RS1 | Contact seals on both sides | Provides superior protection against contaminants and retains lubricant effectively. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-speed or high-temperature environments, preventing preload and ensuring smooth operation. |
| W64 | Solid Oil lubrication | A polymer matrix saturated with oil ensures a consistent lubricant supply, eliminates leakage, and enables maintenance-free operation over a wide temperature range. |
6318-2RS1/C3W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing offers high strength and durability. With a radial dynamic load rating of 32,148 lbf and a static load rating of 24,055 lbf, it is built to withstand significant radial stresses in continuous operation.
- Optimized for Demanding Environments: The C3 clearance is a critical feature for applications with expected thermal growth, preventing seizure and maintaining performance. The contact seals (2RS1) provide an effective barrier, making the bearing suitable for dirty or humid conditions.
- Maintenance-Free Longevity: The integrated Solid Oil (W64) system eliminates the need for re-lubrication, reduces maintenance costs, and prevents lubricant contamination. This feature, combined with the seals, ensures a long service life even in applications where re-lubrication is difficult.
- Balanced Performance: With a limiting speed of 3,600 rpm and an operating temperature range from -30°C to 120°C, this bearing provides a versatile solution for a wide array of industrial machinery.
