209-2ZNRJ Bearing Product Overview & Core Advantages
The 209-2ZNRJ is a metric single row deep groove ball bearing engineered for reliable performance in demanding industrial applications. This bearing features shielded protection (2Z) and a unique snap ring groove on the outer ring (NR), facilitating secure axial location within a housing. Manufactured to ABEC 1 / ISO P0 tolerance standards, it delivers consistent operation and is designed to handle significant radial loads. Its robust construction from chrome steel ensures durability and a long service life, making it a cost-effective solution for a wide range of machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 209 | Basic bearing series, indicating a metric deep groove design with a 45mm bore, 85mm OD, and 19mm width. |
| 2Z | The bearing is shielded on both sides. This provides effective protection against contaminants while allowing for high-speed operation compared to contact seals. |
| NR | The outer ring has a snap ring groove. This feature allows for simplified axial location and secure housing fit, eliminating the need for complex housing shoulders. |
| J | Indicates the snap ring is supplied with the bearing as a fitted component. |
209-2ZNRJ Bearing Structural Features & Performance Benefits
- Robust Load Capacity: With a dynamic load rating of 7913 lbf and a static load rating of 6744 lbf, this bearing is built to handle substantial radial forces in various applications.
- Integrated Snap Ring Design: The outer ring locating snap ring (NRJ) provides a secure and simple method for axial positioning, enhancing assembly efficiency and reliability.
- Shielded Protection: The non-contact 2Z shields protect the internal rolling elements from large particulate contaminants, contributing to a longer operational life without significantly impacting the limiting speed of 8,500 rpm.
- Precision Engineering: Conforming to ABEC 1 / ISO P0 tolerance class and standard CN radial internal clearance, this bearing ensures smooth and precise rotation, minimizing vibration and noise.
- Wide Temperature Range: Suitable for operating temperatures from -30°C to 120°C, offering flexibility for use in various environmental conditions.
