6318-2RSJEM Bearing Product Overview & Core Advantages
The 6318-2RSJEM is a sealed single row deep groove ball bearing engineered for robust performance in demanding industrial environments. This metric bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions. Its primary advantages include extended service life due to its sealed construction, reliable operation under a wide temperature range, and consistent performance backed by ABEC 1 precision. The design offers a compact and versatile solution for applications requiring high reliability with minimal maintenance.
6318-2RSJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6318 | Basic bearing series, indicating a medium-duty, single row deep groove ball bearing with a 90mm bore, 190mm OD, and 43mm width. |
| 2RS | Designates contact-type rubber seals on both sides. This provides superior protection against contaminants and retains lubricant effectively. |
| J | Indicates a pressed steel cage, offering a good balance of strength, speed capability, and cost-effectiveness. |
| EM | Signifies an optimized internal design and enhanced filling slot, which increases the radial dynamic load rating compared to a standard 6318 bearing. |
6318-2RSJEM Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and EM-enhanced internal design enable high radial dynamic load ratings (32,148 lbf) and static load ratings (24,055 lbf), making it suitable for heavy-duty applications.
- Effective Sealing: The 2RS double-contact rubber seals provide excellent defense against dust, moisture, and other contaminants, significantly extending bearing life in harsh conditions. They also effectively retain lubricant.
- Robust Construction: Manufactured from chrome steel for rings, balls, and cage, ensuring high strength, durability, and resistance to wear.
- Standard Precision & Clearance: Built to ABEC 1 (ISO P0) tolerance class with a CN group radial internal clearance, offering reliable performance for a wide range of general industrial uses.
- Versatile Operating Range: Capable of operating within a temperature range of -30°C to 120°C, providing flexibility for various environmental conditions.
