1304 K Bearing Product Overview & Core Advantages
The 1304 K is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. Featuring a metric tapered bore (1:12), this bearing excels at handling significant combined loads (radial and axial) simultaneously. Its compact design, with a 20 mm bore and 52 mm outside diameter, makes it ideal for space-constrained, high-precision machinery. Manufactured from chrome steel and equipped with a nylon cage, it offers reliable performance and is pre-lubricated for immediate use, supporting a wide operating temperature range from -30°C to 110°C.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1304 | Basic bearing designation indicating a double row angular contact ball bearing with a 20 mm bore and 52 mm outside diameter. |

1304 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to support substantial combined loads and moment loads effectively.
- Precision Tapered Bore: The K-suffix tapered bore (1:12) ensures a secure, interference fit on a tapered shaft or with an adapter sleeve, minimizing inner ring creep and enhancing rotational accuracy.
- Optimized Cage Design: The nylon cage contributes to smooth operation, lower friction, and is suitable for high-speed applications up to 18,000 rpm.
- Standard Internal Clearance: Supplied with a CN (Normal) group radial internal clearance, making it suitable for a wide range of standard operating conditions.
- Pre-Lubricated & Ready-to-Use: The bearing comes pre-lubricated, reducing initial setup time and ensuring immediate, reliable operation.
1304 K Bearing Typical Application Areas
The 1304 K bearing is engineered for demanding applications across various industries, including:
- Electric Motors and Gearboxes
- Agricultural Machinery (e.g., tractor transmissions)
- Material Handling Equipment (conveyors, pulleys)
- Industrial Fans and Blowers
- General machinery requiring a robust bearing solution for combined radial and axial loads.
