6218-2ZJEM Bearing Product Overview & Core Advantages
The 6218-2ZJEM is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This precision bearing features integral shields (2Z) for contaminant protection and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable operation and dimensional consistency. Its primary advantage lies in its ability to efficiently handle radial loads while offering moderate axial load capacity in both directions. The design provides a robust and compact solution for machinery requiring high reliability and long service life.
6218-2ZJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6218 | Basic series code denoting a single row deep groove ball bearing with a 90mm bore and 160mm OD. |
| 2Z | Signifies the bearing is equipped with non-contact shields on both sides. This provides effective protection against coarse contaminants while minimizing friction. |
| JEM | Indicates the use of a stamped steel cage (pressed cage) and specifies the radial internal clearance group. |
6218-2ZJEM Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The deep groove raceway and high-quality chrome steel construction enable a high radial dynamic load rating of 21,604 lbf and a static load rating of 16,074 lbf, making it suitable for applications with significant radial forces.
- Contaminant Protection: The 2Z shields on both sides effectively seal the bearing, protecting the internal components from dust and debris, thereby extending service life and reducing maintenance needs.
- Optimized for Standard Applications: Manufactured to ABEC 1 precision with a standard CN radial internal clearance, this bearing offers a cost-effective balance of performance and accuracy for a wide range of industrial uses.
- High-Speed Capability: With a limiting speed of 4,000 rpm and a lightweight stamped steel cage, the bearing is capable of stable operation at high rotational speeds.
6218-2ZJEM Bearing Typical Application Areas
This versatile bearing is ideally suited for a multitude of applications across various sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable, shielded ball bearings
