6304-2ZJEM Bearing Product Overview & Core Advantages
The 6304-2ZJEM is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing excels in handling radial loads with high efficiency. Its compact design and precision manufacturing to ABEC 1 | ISO P0 tolerance class ensure smooth operation and long service life, making it a robust and cost-effective solution for a wide range of industrial machinery.
6304-2ZJEM Bearing Model Code Explained, Specifications & Naming Convention
The model number 6304-2ZJEM provides specific technical details:
- 6304: Standard designation for a single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width.
- 2Z: Indicates the bearing is equipped with shielded seals on both sides. These non-contact shields protect the internal components from large contaminants while minimizing friction.
- JEM: This suffix denotes a specific internal specification, often relating to optimized radial internal clearance (CN group) and material selection for consistent performance.
6304-2ZJEM Bearing Structural Features & Performance Benefits
The 6304-2ZJEM is engineered for durability and reliability. Its single row deep groove raceway is precision-ground to facilitate smooth rotation and effective radial load distribution. The use of chrome steel for all core components (rings, balls, cage) ensures high strength and resistance to wear. The shielded (2Z) design offers significant protection against particulate contamination, extending bearing life in unclean environments. With a limiting speed of 14,000 rpm and a radial dynamic load rating of 3574 lbf, it provides a robust performance envelope for its size. The standard CN clearance makes it suitable for a wide range of operating conditions.
6304-2ZJEM Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, pumps)
