6301-2RSH/VA947 Bearing Product Overview & Core Advantages
The 6301-2RSH is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Engineered with metric dimensions and manufactured to a P6 tolerance class, this bearing delivers high running accuracy. Its key advantage lies in its sealed construction (2RSH), which provides robust protection against contamination and retains lubricant, ensuring long service life and minimal maintenance. This bearing is optimized to handle significant radial loads and is capable of operating at high speeds, making it a versatile and durable solution for a wide range of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6301 | Standard series designation for a single row deep groove ball bearing with a 12mm bore, 37mm OD, and 12mm width. |
| 2RSH | Indicates the bearing is fitted with contact seals on both sides. The "H" signifies a high-temperature resistant NBR seal, offering superior protection and extended service life. |
6301-2RSH/VA947 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RSH double-contact seals effectively shield the internal components from dust, moisture, and other contaminants while retaining the factory-applied grease lubrication. This design significantly enhances bearing life and enables maintenance-free operation in many environments.
- High Load Capacity: The deep groove raceway and high-quality chrome steel construction enable the bearing to support high radial dynamic load ratings of 2271 lbf and radial static load ratings of 933 lbf.
- High-Speed Capability: The combination of a stainless steel cage, precision P6 tolerance, and optimized grease lubrication allows for a high limiting speed of 14,000 rpm.
- Wide Operating Range: With a specified temperature range from -30°C to 120°C, this bearing is suitable for applications subject to varying thermal conditions.
6301-2RSH/VA947 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, sealed, and high-performance solution. Common uses include:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
