608-2ZJEM Bearing Product Overview & Core Advantages
The 608-2Z is a metric single row deep groove ball bearing designed for high performance in compact spaces. This shielded bearing offers reliable operation and is engineered to primarily handle radial loads. Its key advantages include a robust construction using chrome steel for all critical components, ensuring durability and consistent performance. The inclusion of shields (2Z) provides effective protection against contamination without significantly increasing rotational friction, making it suitable for applications requiring low maintenance and long service life. With its ABEC 1 (ISO P0) tolerance class, it delivers dependable precision for a wide range of industrial uses.
608-2ZJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Benefit |
|---|---|---|
| 608 | Standard series designation for a deep groove ball bearing with an 8mm bore, 22mm OD, and 7mm width. | Defines the core bearing dimensions and internal geometry. |
| -2Z | Specifies that the bearing is equipped with non-contact shields on both sides. | Offers effective protection against dust and large particles while allowing for high-speed operation due to low friction. Enables a maintenance-free design in many applications. |
608-2ZJEM Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and continuous shoulder design enable efficient handling of radial loads and moderate axial loads in both directions.
- Shielded Protection: The 2Z shields are pressed into the outer ring, creating an effective barrier against contaminants. This preserves the bearing's internal integrity and lubricant, extending its operational life without the need for re-lubrication.
- High-Grade Material: Manufactured entirely from chrome steel (rings, balls, and cage), providing high hardness, wear resistance, and dimensional stability under load.
- Optimized for Speed: The combination of a chrome steel cage and low-friction shields supports a high limiting speed of 34,000 rpm, making it an excellent high-speed bearing choice.
- Standard Precision: Built to ABEC 1 / ISO P0 tolerance standards with CN radial internal clearance, ensuring reliable and consistent performance for general industrial applications.
