1213 C/3 Bearing Product Overview & Core Advantages
The 1213 C/3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Its metric design features a 65 mm bore, 120 mm outside diameter, and 23 mm width, offering a compact solution for space-constrained assemblies. This precision bearing is engineered to handle significant radial loads while accommodating axial loads in both directions, making it ideal for high-reliability industrial machinery. Manufactured from chrome steel with a nylon cage, it delivers excellent durability and smooth operation.
1213 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| C | Designates a specific internal design and contact angle optimized for high rigidity and combined load capacity. |
| 3 | Indicates the radial internal clearance group is C3, providing greater than normal clearance for applications involving thermal expansion or heavy interference fits. |
1213 C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized contact angle create a robust structure capable of supporting high radial dynamic load ratings (7898 lbf) and handling combined loads effectively, ensuring stable shaft support under demanding conditions.
- Optimized for Performance: The lightweight nylon cage ensures smooth operation and reduced friction, contributing to the bearing's high limiting speed of 7,000 rpm. The specified C3 radial internal clearance accommodates thermal expansion in precision assemblies.
- Precision & Durability: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers excellent wear resistance and long service life. The open seal type allows for custom lubrication solutions tailored to specific operational needs.
- Broad Operating Range: With a temperature range from -30°C to 110°C and being pre-lubricated, this bearing is suitable for a wide array of industrial environments.
