6304-2RSH/VA947 Bearing Product Overview & Core Advantages
The 6304-2RSH is a single row deep groove ball bearing designed for exceptional reliability and performance in demanding applications. This metric bearing features integral contact seals (2RSH) and pre-applied grease lubrication, making it a maintenance-free solution for a wide range of industrial uses. Its key advantages include the ability to handle significant radial loads, robust construction for long service life, and optimized internal geometry for smooth, quiet operation. Engineered with P6 tolerance, it offers high running accuracy, making it suitable for applications requiring precise shaft guidance.
6304-2RSH/VA947 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Benefit |
|---|---|---|
| 6304 | Basic Bearing Series & Size | Denotes a standard single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| 2RS | Seal Type | Indicates the bearing is fitted with two contact seals (one on each side). |
| H | Seal Material | Specifies that the seals are made of NBR (Nitrile Rubber), offering excellent resistance to oil, water, and wear. |
6304-2RSH/VA947 Bearing Structural Features & Performance Benefits
Optimized Internal Geometry & High Load Capacity: The deep groove raceway and precision-ground components enable the bearing to carry high radial dynamic load ratings (3777 lbf) and radial static load ratings (1754 lbf). This robust design ensures reliable performance under significant stress.
Sealed & Lubricated for Life: The 2RSH seals effectively retain the factory-applied grease lubricant and exclude contaminants like dust and moisture. This creates a maintenance-free system ideal for sealed-for-life applications, reducing total cost of ownership.
High-Speed Capability & Precision: The combination of a stainless steel cage, high-grade chrome steel rings and balls, and P6 tolerance class contributes to stable operation at high rotational speeds (limiting speed of 9,500 rpm) with minimal vibration and noise.
Wide Operating Temperature Range: With a specified temperature range from -30°C to 120°C, this bearing is suitable for use in diverse environmental conditions.
6304-2RSH/VA947 Bearing Typical Application Areas
