6304-RSH/C3 Bearing Product Overview & Core Advantages
The 6304-RSH/C3 is a high-performance single row deep groove ball bearing engineered for demanding industrial 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 robust C3 radial internal clearance for thermal expansion management in high-speed or high-temperature environments, and an integrated RSH seal for superior contamination protection. Manufactured from high-grade chrome steel and built to ABEC 1 | ISO P0 tolerance standards, it delivers reliable, long-lasting performance in compact assemblies.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Standard series designation for a single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| RSH | Indicates a contact seal on one side, providing excellent protection against contaminants and retention of lubricant. |
| /C3 | Denotes a greater than normal radial internal clearance. This is critical for applications with high rotational speeds or significant temperature gradients to prevent pre-loading and ensure smooth operation. |
6304-RSH/C3 Bearing Structural Features & Performance Benefits
- Optimized Sealing: The RSH seal effectively shields the bearing's internals from dust, moisture, and other contaminants, significantly extending service life and enabling use in harsh environments. It also helps retain lubricant.
- Radial Internal Clearance (C3): The C3 clearance is a defining feature that accommodates shaft and housing fits, as well as thermal expansion during operation. This prevents excessive friction and heat buildup, contributing to higher effective limiting speeds and overall reliability.
- Robust Load Capacity: With a dynamic load rating of 3574 lbf and a static load rating of 1765 lbf, this bearing offers substantial radial load capacity for its compact dimensions, ensuring durability under demanding conditions.
- Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with tight dimensional tolerances, this bearing provides consistent, high-quality performance essential for smooth and precise rotation.
