6304-2RSH Bearing Product Overview & Core Advantages
The 6304-2RSH is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This sealed bearing features a robust construction that provides high reliability and long service life. Its primary advantage lies in its ability to accommodate significant radial loads while also handling moderate axial loads in both directions. Manufactured to a P6 tolerance class, it offers high precision and smooth operation, making it an ideal choice for applications requiring consistent performance and low noise levels.
6304-2RSH Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Standard designation for a single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| 2RS | Indicates contact seals on both sides of the bearing. The "H" suffix denotes that the seals are made of NBR (Nitrile Rubber), providing excellent protection against contaminants and moisture retention. |
| H | Specifies the seal material as NBR, offering a wide temperature range and good resistance to oils and aging. |
6304-2RSH Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway geometry is optimized to support high radial dynamic load ratings (3777 lbf) and static loads (1754 lbf). The stainless steel cage ensures dimensional stability and reliable performance under high-speed conditions.
- Sealed & Pre-Lubricated Design: The integral 2RSH contact seals effectively shield the internal components from dust, dirt, and moisture, while the factory-applied grease lubrication ensures immediate operation and long-term, maintenance-free service.
- High-Speed Capability: With a limiting speed of 9,500 rpm, this bearing is suitable for a wide range of high-speed applications. The precision P6 tolerance and optimized internal clearance (CN) contribute to smooth running and reduced vibration.
- Durable Material Construction: Manufactured from chrome steel for rings and balls, the bearing provides high hardness and wear resistance, ensuring extended operational life even in challenging environments.
