6304-2ZNRJEM Bearing Product Overview & Core Advantages
The 6304-2ZNRJEM is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing features a snap ring groove on its outer ring for secure axial location within a housing, combined with integrated shields (2Z) to protect against contamination. Engineered from high-grade chrome steel, it offers a robust solution for primarily radial loads, delivering high reliability, long service life, and simplified assembly in compact designs.
Model Code Breakdown
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2Z | Non-contact steel shields on both sides | Protects the bearing interior from dust and debris while minimizing friction and heat generation. |
| NR | Snap ring groove on the outer ring | Enables secure axial location and simplifies housing design, eliminating the need for complex shoulder machining. |
| JEM | JEM standard (Japan) for specific internal design and radial internal clearance (CN) | Ensures consistent performance, interchangeability, and optimal operation under standard conditions. |
6304-2ZNRJEM Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The single row deep groove raceway geometry is precision-engineered to efficiently carry significant radial dynamic load ratings of 3574 lbf, making it a reliable choice for rotating shafts.
- Secure Axial Location: The integrated snap ring groove (NR) provides a positive locking mechanism, preventing creep and simplifying the overall assembly process in the housing.
- Contamination Protection: The shielded design (2Z) offers effective protection against particulate ingress, enhancing bearing life in environments where complete sealing is not required.
- Standard Precision & Clearance: Manufactured to ABEC 1 | ISO P0 tolerance class with CN group radial internal clearance, this bearing provides consistent, high-quality performance for a wide range of general industrial applications.
6304-2ZNRJEM Bearing Typical Application Areas
The 6304-2ZNRJEM is ideally suited for a variety of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Material Handling Conveyors
- Industrial Fans and Blowers
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
