6304-2Z/C4 Bearing Product Overview & Core Advantages
The 6304-2Z/C4 is a single row deep groove ball bearing designed for reliable performance in demanding applications. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions. The bearing features integrated shields (2Z) for effective contamination protection and is supplied with a greater radial internal clearance (C4), making it exceptionally suitable for applications involving thermal expansion or where interference fits are used. This combination delivers a robust, long-lasting solution for general industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6304 | Standard bearing series designation, indicating a metric, single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width. |
| 2Z | Signifies the bearing is shielded on both sides. These non-contact steel shields protect against contamination while minimizing friction. |
| C4 | Indicates a greater radial internal clearance than the normal (CN) group. This is critical for applications with shaft or housing fits that reduce clearance, or where operational heat generation is expected. |
6304-2Z/C4 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing offers high strength and durability. Its deep groove raceway geometry is optimized to support high radial dynamic load ratings (3574 lbf) and static loads (1765 lbf).
- Effective Sealing with Shields: The 2Z shields provide a high level of protection against dust and other particulates, helping to extend the bearing's service life in contaminated environments without the added friction of contact seals.
- Optimized Internal Clearance: The C4 clearance is a key performance feature. It accommodates thermal expansion in the system, preventing preload and potential seizure, which is vital for stable operation across its specified temperature range (-30° to 120 °C).
- Standard Precision & Speed: Conforming to ABEC 1 | ISO P0 tolerance class, it ensures consistent and reliable performance for a wide range of industrial applications, with a limiting speed of 14,000 rpm.
6304-2Z/C4 Bearing Typical Application Areas
This versatile bearing is ideally suited for a multitude of applications, including:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Pumps and general machinery requiring reliable rotational support.
