1213JC3 Bearing Product Overview & Core Advantages
The 1213JC3 is a double row angular contact ball bearing designed for demanding applications requiring high load capacity and robust performance. This metric bearing features an open design, enabling it to handle significant combined loads—both radial and axial forces—simultaneously. Its construction offers high rigidity and stable operation, making it an excellent choice for machinery where precision and reliability are paramount. The bearing is pre-lubricated and features a generous C3 radial internal clearance, accommodating thermal expansion in various operating conditions.
1213JC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1213 | Standard bearing series designation indicating the bearing dimensions: 65mm bore, 120mm OD, 23mm width. |
| J | Indicates a pressed steel cage, optimized for high-speed operation. |
| C3 | Specifies a greater than normal radial internal clearance, suitable for applications with thermal expansion or where interference fits are used. |
1213JC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide exceptional stiffness, enabling the bearing to support heavy radial loads and moderate axial loads from both directions. This makes it ideal for applications with significant combined loads.
Optimized for Performance: The steel cage (J) ensures stability and guidance of the balls at high rotational speeds, contributing to the bearing's reliable performance. The C3 clearance allows for thermal expansion, preventing preload and potential seizure in high-temperature environments.
Durability and Compliance: Manufactured from chrome steel for both rings and balls, the bearing offers high wear resistance and long service life. It is pre-lubricated for immediate use and complies with ROHS and REACH environmental standards.
1213JC3 Bearing Typical Application Areas
The 1213JC3 is suited for a wide range of industrial machinery requiring robust performance and high load capacity. Common applications include:
- Industrial Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- Electric Motors and Pumps
- General Industrial Machinery with heavy radial loads
