1213 C3 Bearing Product Overview & Core Advantages
The 1213 C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and operational stability. This precision bearing is engineered to accommodate significant combined loads, including radial and bidirectional axial forces, within a compact design. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring reliable performance under varying operational conditions. Manufactured from high-grade chrome steel, it offers excellent durability and is pre-lubricated for immediate use.
1213 C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1213 | Standard bearing designation indicating a bearing size of 65mm bore, 120mm OD, and 23mm width. |
| C3 | Specifies a greater than normal radial internal clearance for applications involving thermal expansion or shaft interference fits. |
1213 C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to handle substantial combined loads effectively. With a dynamic load rating of 7898 lbf and static load rating of 3150 lbf, it delivers reliable performance in demanding applications.
Optimized Internal Clearance: The C3 clearance accommodates thermal expansion and interference fits, preventing premature failure due to excessive preload while maintaining optimal operational performance.
High-Speed Capability: Featuring a nylon cage, this bearing achieves a limiting speed of 7000 rpm, making it suitable for various high-speed applications while maintaining stability and reducing friction.
Maintenance-Friendly Design: The open seal type allows for easy re-lubrication, while the pre-lubrication ensures immediate operation upon installation, reducing maintenance requirements.
