6312-2ZNRJEM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Provides effective protection against dust and other contaminants while maintaining low friction and high-speed capability. |
| NR | Snap ring groove on the outer ring | Enables simplified axial location and secure mounting within a housing, reducing assembly complexity. |
| JEM | Japan Electric Machine (JEM) standard snap ring | Ensures compatibility with standardized housing designs and components. |
6312-2ZNRJEM Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. With a radial dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, it is built to withstand significant operational stresses.
- Optimized for Speed & Precision: The deep groove raceway and precision-ground components contribute to smooth operation and a limiting speed of 5,300 rpm. The standard CN radial internal clearance and ABEC 1 precision ensure consistent performance in a wide range of applications.
- Simplified Assembly & Axial Location: The integrated snap ring groove on the outer ring allows for easy and secure axial positioning, eliminating the need for complex housing shoulders and simplifying the overall design.
- Contamination Protection: The 2Z non-contact shields effectively seal the bearing interior from dust and debris, extending lubricant life and bearing reliability without a significant impact on speed.
