6303-2RSH/C3HT Bearing Product Overview & Core Advantages
The 6303-2RSH/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. Engineered with metric dimensions, it excels in handling significant radial loads while also accommodating moderate axial loads in both directions. Its sealed construction ensures protection against contaminants, making it a highly reliable and durable choice for a wide range of industrial machinery. This bearing is characterized by its high limiting speed and C3 radial internal clearance, which is suitable for applications with thermal expansion or where interference fits are used.
6303-2RSH/C3HT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6303 | Basic Bearing Series & Size | Denotes a medium duty, single row deep groove ball bearing with a 17mm bore, 47mm OD, and 14mm width. |
| 2RSH | Seal Type | Indicates contact seals on both sides. The "RSH" suffix signifies high-performance nitrile rubber (NBR) seals, offering superior contamination exclusion and grease retention compared to standard seals. |
| C3 | Radial Internal Clearance | Specifies a greater than normal radial internal clearance. This is crucial for applications involving thermal expansion, heavy interference fits, or where operational heat generation is expected. |
6303-2RSH/C3HT Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 3057 lbf and a static load rating of 1495 lbf, ensuring long service life under substantial radial loads.
- Sealed & Protected Design: The 2RSH contact seals effectively shield the internal components from dust, moisture, and other contaminants. This design enhances reliability and provides a maintenance-free solution for the bearing's operational lifespan.
- Optimized for Demanding Conditions: The C3 radial clearance accommodates dimensional changes from heat or press-fits, preventing premature failure due to excessive preload. This makes it ideal for applications with fluctuating thermal conditions.
- High-Speed Capability: With a limiting speed of 15,000 rpm, it is suitable for high-velocity applications. The precision ABEC 1 (ISO P0) tolerance class ensures consistent and smooth operation.
6303-2RSH/C3HT Bearing Typical Application Areas
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
