Product Overview and Core Advantages
The 62302-2RS1/C3W64 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing excels at handling primarily radial loads and offers high operational reliability. Its key advantages include a sealed design for contamination protection, Solid Oil lubrication for long service life, and a C3 radial internal clearance suitable for applications with thermal expansion. With a limiting speed of 12,000 rpm and manufactured to ABEC 1 | ISO P0 tolerance class, it provides a robust and cost-effective solution for a wide range of industrial machinery.
62302-2RS1/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 62302 | Basic designation for a single row deep groove ball bearing with a 15mm bore. | Standardized sizing for easy interchangeability. |
| 2RS1 | Designates contact seals on both sides of the bearing. | Provides excellent protection against contaminants and retains lubricant. |
| C3 | Indicates a radial internal clearance greater than the Normal (CN) group. | Accommodates thermal expansion in applications with high operating temperatures or interference fits. |
| W64 | Manufacturer-specific suffix for Solid Oil lubrication. | Ensures a maintenance-free, long-life lubrication solution that is resistant to wash-out and leakage. |
Structural Features and Performance Benefits
The performance of the 62302-2RS1/C3W64 is derived from its specific construction and material selection.
- Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing offers a dynamic load rating of 2563 lbf and a static load rating of 1214 lbf, ensuring durability under significant radial loads.
- Maintenance-Free Operation: The combination of 2RS1 contact seals and factory-filled Solid Oil eliminates the need for re-lubrication. This makes the bearing ideal for hard-to-reach locations and reduces total cost of ownership.
- Thermal Stability: The specified C3 clearance allows for differential thermal expansion between the inner and outer rings, preventing preload and potential seizure in applications with operating temperatures up to 120°C.
- Precision and Smooth Operation: Built to ABEC 1 precision with a chrome steel cage, the bearing ensures smooth running and low vibration, contributing to the overall efficiency of the assembly.
