212NRJ Bearing Product Overview & Core Advantages
The 212NRJ is a single row deep groove ball bearing designed for robust performance in general industrial applications. Engineered to primarily handle radial loads, this open-type bearing offers reliable operation and excellent value. Its construction from high-grade chrome steel ensures durability and consistent performance, while the standard ABEC 1 (ISO P0) tolerance class makes it a versatile choice for a wide range of machinery. A key distinguishing feature is the snap ring fitted on the outer ring, which provides secure axial location within the housing, simplifying assembly and enhancing operational stability.
Model Code Breakdown
| Model Segment | Technical Meaning |
|---|---|
| 212 | Basic bearing designation, defining the core dimensions and series. |
| NR | Specifies that the outer ring is equipped with a snap ring groove and a fitted snap ring. This feature aids in axial positioning. |
| J | Indicates that the bearing is of the Pressed Steel Cage construction, known for its lightweight and high-speed capability. |
212NRJ Bearing Structural Features & Performance Benefits
- Simplified Assembly and Location: The integrated snap ring on the outer ring eliminates the need for complex housing shoulders, reducing machining costs and ensuring secure axial location.
- High-Speed Capability: The lightweight and robust pressed steel cage (J) minimizes centrifugal forces, contributing to the bearing's high limiting speed of 6,700 rpm.
- Robust Load Capacity: Manufactured from high-quality chrome steel for both rings and balls, this bearing offers a high dynamic load rating for its compact bearing dimensions (60mm bore, 110mm OD, 22mm width), ensuring long service life under significant radial loads.
- Standardized Precision: Conforms to ABEC 1 (ISO P0) tolerance class and standard CN radial internal clearance, providing reliable and predictable performance for most industrial applications.
- Versatile Operating Range: With a temperature range from -30°C to 120°C, it is suitable for various environmental conditions.
