6304 Bearing Product Overview & Core Advantages
The 6304 is a single row deep groove ball bearing designed for outstanding performance in a wide range of industrial applications. As a metric bearing, it excels at handling primarily radial loads and offers high operational reliability. Its key advantages include a robust chrome steel construction for durability, a stainless steel cage for stability at moderate speeds, and compliance with ABEC-1 precision tolerances, making it a cost-effective and versatile solution for general machinery where high precision is not the primary concern.
6304 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 63 | Series Code | Indicates a medium-duty, single row deep groove ball bearing design. |
| 04 | Bore Diameter Code | Specifies a standard 20 mm bore diameter (04 x 5 = 20 mm). |
| (No Suffix) | Standard Design | Denotes an open (unsealed) bearing with CN group radial internal clearance and an ABEC-1 tolerance class. |
6304 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is engineered to efficiently support high radial dynamic load ratings (3574 lbf) and moderate axial loads in both directions.
- Durable Construction: Rings and balls made from high-carbon chrome steel provide excellent resistance to wear and fatigue, ensuring a long service life.
- Stable Cage Performance: The stainless steel cage ensures smooth ball guidance and reliable operation, contributing to the bearing's limiting speed of 14,000 rpm.
- Standardized Precision: Manufactured to ABEC-1 tolerance standards with CN group radial internal clearance, this bearing offers consistent performance suitable for a broad spectrum of general-purpose applications.
6304 Bearing Typical Application Areas
This versatile ball bearing is widely used across various industries due to its robust design and reliable performance. Common applications include:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery
