6302-2RSH/C3WT Bearing Product Overview & Core Advantages
The 6302-2RSH/C3 is a sealed deep groove ball bearing designed for robust performance in demanding applications. As a single row bearing, it excels at handling high radial loads while also accommodating moderate axial loads in both directions. Its key advantages include extended service life through effective sealing, reliable operation under a C3 radial internal clearance for specific application fits, and compliance with international environmental standards (ROHS, REACH). This bearing offers a compact and cost-effective solution for general industrial machinery requiring dependable performance.
6302-2RSH/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6302 | Basic bearing series, indicating a medium duty, metric deep groove ball bearing with a 15mm bore, 42mm OD, and 13mm width. |
| 2RSH | Designates contact seals on both sides. The "RSH" suffix indicates high-performance Nitrile Rubber (NBR) seals with a steel insert, offering superior protection against contaminants compared to standard seals. |
| C3 | Specifies a greater than normal radial internal clearance. This is ideal for applications with thermal expansion, interference fits, or where a heavier preload is not required. |
6302-2RSH/C3WT Bearing Structural Features & Performance Benefits
Effective Sealing for Contamination Resistance: The 2RSH double-contact seals provide an excellent barrier against dust, moisture, and other contaminants, significantly extending bearing life and lubrication integrity in harsh environments. This makes the bearing suitable for maintenance-free operation over long periods.
Optimized Internal Clearance for Versatility: The C3 clearance group allows for stable operation in applications where bearing rings may experience differential heating (e.g., electric motors) or where press fits on both rings reduce the internal clearance. This prevents excessive preload and potential overheating.
Robust Construction for High Load Capacity: Manufactured from high-quality chrome steel for both rings and balls, this bearing achieves a high dynamic load rating of 2563 lbf and a static load rating of 1225 lbf, ensuring durability under significant radial stresses.
Standard Precision for Reliable Operation: Built to ABEC 1 | ISO P0 tolerance class, it provides the necessary runout and dimensional accuracy for the vast majority of industrial applications, guaranteeing smooth and consistent performance.
6302-2RSH/C3WT Bearing Typical Application Areas
- Electric Motors: Ideal for use as end-shield bearings in small to medium-sized AC/DC motors, where the C3 clearance accommodates shaft expansion.
- Industrial Gearboxes and Transmissions: Provides reliable support for shafts in light to medium-duty gearboxes.
- Material Handling Equipment: Commonly found in conveyor pulleys, rollers, and fans.
- Agricultural Machinery: Used in various components requiring sealed bearings to operate in dusty and dirty conditions.
- General Industrial Machinery: A versatile choice for pumps, compressors, and other machinery where radial load support and environmental protection are key.
