6310-2ZNRJEM Bearing Product Overview & Core Advantages
The 6310-2ZNRJEM is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This shielded bearing excels in handling significant radial loads while offering protection from contaminant ingress. Its key advantages include a high radial dynamic load rating of 13,938 lbf, a compact design with a 50 mm bore, and compliance with ABEC 1 | ISO P0 tolerance standards for reliable, precision operation. The inclusion of a snap ring on the outer ring facilitates secure and simplified mounting in housings.
6310-2ZNRJEM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Protects the bearing interior from dust and other contaminants while maintaining low friction and high-speed capability. |
| NR | Snap ring groove on the outer ring | Enables secure axial location and simplified installation in housings, eliminating the need for complex housing shoulders. |
| JEM | Japan Energy Corporation (JEC) grease specification | Indicates the bearing is pre-lubricated with a high-quality grease suitable for a wide operating temperature range. |
6310-2ZNRJEM Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is engineered to efficiently support high radial loads. With a radial dynamic load rating of 13,938 lbf, it provides reliable performance under significant stress.
- Contamination Protection & Speed: The non-contact 2Z shields retain the factory-applied JEM grease and exclude harmful particles. This design maintains low operating torque, contributing to the bearing's high limiting speed of 6,000 rpm.
- Simplified Mounting & Axial Security: The snap ring (NR) feature allows for straightforward assembly and provides positive axial location, enhancing the overall rigidity and stability of the application.
- Precision & Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class with standard CN clearance, this bearing ensures consistent running accuracy and smooth operation, making it a dependable precision bearing for a wide range of uses.
