6204-RSH/C3 Bearing Product Overview & Core Advantages
The 6204-RSH/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding 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 high limiting speed of 15,000 rpm, a generous C3 radial internal clearance for thermal expansion in high-temperature environments, and a robust construction from chrome steel. The integrated RSH seal ensures reliable protection against contamination, making it a durable and maintenance-friendly solution for a wide range of industrial machinery.
6204-RSH/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6204 | Standard designation for a single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width. | Defines the core bearing dimensions and type. |
| RSH | Contact seal made of Nitrile Butadiene Rubber (NBR) on both sides. | Provides superior sealing effectiveness against contaminants like dust and moisture, retaining lubricant for extended service life. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Accommodates thermal expansion in applications with high operating temperatures or where fits result in a reduction of internal clearance, preventing premature failure. |
6204-RSH/C3 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Quality Steel: The optimized raceway geometry and the use of chrome steel for rings and balls ensure smooth operation, high dynamic load rating (2878 lbf), and long-term durability.
- Robust Sealing with RSH: The low-friction, contact rubber seals on both sides effectively shield the bearing interior from contaminants, making it ideal for dirty or humid environments and contributing to its maintenance-free characteristic.
- Optimized for Speed & Temperature: The precision ABEC 1 | ISO P0 tolerance and C3 clearance allow for stable operation at high rotational speeds (up to 15,000 rpm) and across a wide temperature range (-30°C to 120°C).
- Versatile Load Capacity: As a deep groove ball bearing, it is primarily designed for radial loads but can also support significant bidirectional axial loads, offering application flexibility.
6204-RSH/C3 Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
