6304N/C3 Bearing Product Overview & Core Advantages
The 6304N/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This metric bearing is characterized by its open design and C3 radial internal clearance, making it ideally suited for applications with thermal expansion or where interference fits are used. Its primary advantages include high load-carrying capacity for both radial and light axial loads, reliable operation across a wide temperature range, and compliance with major environmental directives.
6304N/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6304: Basic model number indicating a single row deep groove ball bearing with a 20mm bore, 52mm OD, and 15mm width.
- N: Signifies a snap ring groove on the outer ring, enabling secure axial location within a housing.
- C3: Denotes a greater than normal radial internal clearance. This is critical for applications involving high operating temperatures or heavy interference fits, preventing excessive preload and potential bearing seizure.
6304N/C3 Bearing Structural Features & Performance Benefits
The open structure of the 6304N/C3 allows for high-speed operation and facilitates the application of specific lubricants tailored to the application. The snap ring groove (N) provides a simple and effective method for axial positioning, enhancing mounting stability and simplifying assembly. Manufactured from high-grade chrome steel for both rings and balls, this bearing ensures durability and a long service life. The C3 clearance is a key performance feature, accommodating thermal expansion and ensuring smooth, reliable operation under varying thermal conditions.
6304N/C3 Bearing Typical Application Areas
The 6304N/C3 is widely used across various industries due to its robust design and versatile clearance. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Agricultural Machinery
- Material Handling Equipment
- General machinery where secure axial location and compensation for thermal expansion are required.
