6018-2RSJEM Bearing Product Overview & Core Advantages
The 6018-2RSJEM is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric sealed bearing excels at handling primarily radial loads while offering reliable operation. Its key advantages include a high radial dynamic load rating of 13,084 lbf and a robust sealed design that protects against contamination, ensuring long service life and reduced maintenance needs. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent and reliable performance for a wide range of industrial machinery.
6018-2RSJEM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2RS | Contact Seals on Both Sides | Provides superior protection against the ingress of contaminants like dust and moisture, significantly enhancing bearing life in harsh environments. |
| J | Pressed Steel Cage | Offers a robust and cost-effective solution for cage construction, suitable for high-speed applications. |
| EM | Optimized Internal Design & Clearance | Features an internal design optimized for low noise and low vibration, paired with a CN radial internal clearance for versatile operating conditions. |
6018-2RSJEM Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The double-sided contact seals (2RS) create an effective barrier, making the bearing pre-lubricated and maintenance-free for its entire service life, ideal for applications where re-lubrication is difficult.
- High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating, ensuring durability under significant radial stresses.
- Stable High-Speed Operation: The combination of the pressed steel cage (J) and the optimized internal design (EM) contributes to smooth operation and a high limiting speed of 4,800 rpm, minimizing vibration and noise.
- Precision and Reliability: Built to ABEC 1 (ISO P0) tolerance class, it guarantees dimensional accuracy and running precision for consistent performance in general industrial applications.
6018-2RSJEM Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Pumps and Fans
