212-ZNRJ Bearing Product Overview & Core Advantages
The 212-ZNRJ is a single row deep groove ball bearing designed for high reliability in demanding industrial applications. Engineered with shielded construction on one side and an outer ring snap ring groove, it offers effective protection against contamination while facilitating secure axial location within the housing. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing provides consistent performance for general precision requirements. Its robust chrome steel construction ensures durability and a long service life under radial loads.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 212 | Basic bearing series and size designation. |
| Z | One side shielded (metal shield). Protects against contaminants from one direction. |
| NR | Outer ring features a snap ring groove. This allows for simplified axial location and secure housing fit. |
| J | Indicates the bearing is supplied without lubrication, allowing for application-specific greasing. |
