6308-2RSJEM Bearing Product Overview & Core Advantages
The 6308-2RS JEM is a sealed deep groove ball bearing designed for reliable performance in demanding applications. As a single row bearing, it offers an optimal balance of high load capacity and operational efficiency. Its primary strength lies in its ability to accommodate significant radial loads, making it a versatile and robust solution for a wide range of industrial machinery. The inclusion of integral seals (2RS) ensures excellent protection against contaminants and retains lubrication, contributing to extended service life and reduced maintenance requirements, even in harsh environments.
6308-2RSJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Basic bearing series designation, indicating a medium-duty, metric deep groove ball bearing with a 40 mm bore, 90 mm OD, and 23 mm width. |
| 2RS | The bearing is fitted with contact seals on both sides. These seals provide superior protection from dust, dirt, and moisture compared to shields. |
| JEM | Indicates the specific design and manufacturing specifications, often relating to internal clearances, tolerances, and material grades that meet JIS (Japanese Industrial Standards) or other specific requirements. |
6308-2RSJEM Bearing Structural Features & Performance Benefits
- Robust Construction for High Load Capacity: Manufactured from high-grade chrome steel for rings, balls, and cage, this bearing is engineered to handle a high radial dynamic load rating of 915 lbf and a radial static load rating of 5395 lbf, ensuring durability under significant stress.
- Enhanced Sealing for Contamination Resistance: The double-contact rubber seals (2RS) effectively exclude contaminants and retain grease, making the bearing suitable for dirty or humid environments and contributing to its long, maintenance-free service life.
- Precision and Consistency: Built to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, it guarantees reliable and consistent performance for general industrial applications.
- Optimized for Medium-High Speeds: With a limiting speed of 7,500 rpm, it is well-suited for applications requiring efficient operation at medium to high rotational velocities.
6308-2RSJEM Bearing Typical Application Areas
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
