62304-2RS1 Bearing Product Overview & Core Advantages
The 62304-2RS1 is a single row deep groove ball bearing designed for high performance and reliability in demanding applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its sealed construction (2RS1) and pre-lubrication with grease ensure long service life and maintenance-free operation, making it an ideal choice for applications requiring robust performance with minimal upkeep. Manufactured to a P6 tolerance class, it offers superior running accuracy and consistent performance.
62304-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 62304 | Basic designation indicating a single row deep groove ball bearing with a 20mm bore, 52mm OD, and 21mm width. | Defines the standard bearing dimensions and type. |
| 2RS1 | The bearing is fitted with two contact seals (one on each side) made of NBR rubber. | Provides excellent protection against contamination and retains lubricant effectively, enhancing bearing life and reliability. |
62304-2RS1 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class with a CN radial internal clearance, this bearing ensures high running accuracy, low vibration, and stable operation, contributing to overall system high rigidity.
- Robust Load Capacity: With a dynamic load rating of 3574 lbf and a static load rating of 1754 lbf, it is engineered to handle significant radial loads reliably.
- Optimized Speed Performance: The stainless steel cage and effective sealing contribute to a high limiting speed of 9,500 rpm, suitable for various high-speed applications.
- Maintenance-Free & Long-Lasting: The 2RS1 contact seals and factory-applied grease lubrication create a shielded, lubricated environment. This design prevents contaminant ingress and lubricant leakage, offering a long, maintenance-free service life within the specified temperature range of -30°C to 120°C.
- Premium Material Construction: The use of chrome steel for rings and balls, combined with a stainless steel cage, provides excellent durability and corrosion resistance.
