6304-2RSH/C3WT Bearing Product Overview & Core Advantages
The 6304-2RSH/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This sealed bearing features robust construction and is engineered to handle primarily radial loads, making it a versatile and reliable component. Its key advantages include extended service life due to effective sealing, high operational reliability, and suitability for a wide range of industrial machinery. The C3 radial internal clearance makes it particularly well-suited for applications with thermal expansion or where interference fits are used.
6304-2RSH/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6304 | Basic bearing designation (Metric, 20mm bore, 52mm OD, 15mm width) | Standardized dimensions for easy interchangeability. |
| 2RSH | Two (2) Contact Seals (RS) on both sides, made of NBR rubber (H) | Provides superior contamination protection and effective grease retention compared to standard seals. |
| C3 | Radial internal clearance greater than Normal (CN) | Accommodates thermal expansion in the shaft or housing, preventing preload and ensuring smooth operation. |
6304-2RSH/C3WT Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-quality chrome steel construction (rings, balls, cage) provide high dynamic and static load capacity, ensuring durability under significant radial loads.
- Superior Sealing with 2RSH: The contact seals on both sides effectively shield the bearing interior from contaminants like dust and moisture, while retaining lubricant. This significantly extends the bearing's service life and reduces maintenance needs.
- Optimized for Thermal Conditions (C3 Clearance): The greater-than-normal radial internal clearance prevents excessive preload that can occur due to thermal expansion in the application, maintaining performance and preventing premature failure.
- High-Speed Capability: With a limiting speed of 14,000 rpm and a precision class of ABEC 1 | ISO P0, this bearing offers smooth and stable operation at high rotational speeds.
6304-2RSH/C3WT Bearing Typical Application Areas
This bearing is ideal for a wide array of applications requiring reliable, sealed performance, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (conveyors, fans)
- Agricultural Machinery
- Automotive Components (alternators, idlers)
