1213 Bearing Product Overview & Core Advantages
The 1213 is a metric double row deep groove ball bearing engineered for robust performance in demanding applications. Its double row ball construction provides superior high rigidity and increased radial load capacity compared to single row designs, making it an ideal solution for compact spaces requiring significant load support. Manufactured from high-grade chrome steel and featuring a lightweight nylon cage, this bearing is optimized for smooth operation and is pre-lubricated for immediate use, ensuring high reliability and long service life in a wide temperature range from -30° to 110 °C.
1213 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 1213 | Standard designation for a double row deep groove ball bearing with a 65mm bore diameter, 120mm outside diameter, and 23mm width. |
| Open (Seal Type) | The bearing is unsealed (Open), allowing for higher limiting speeds and facilitating relubrication in service if required by the application. |
| Cylindrical (Bore Type) | Features a cylindrical bore for a precise interference fit on a shaft, ensuring secure mounting and optimal power transmission. |
| CN (Radial Internal Clearance) | Specifies a normal radial internal clearance group, which is the standard for most general applications. |
1213 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design significantly increases the bearing's stiffness and its ability to handle heavy radial loads (7898 lbf dynamic, 3150 lbf static), preventing deflection under load and ensuring positional accuracy.
- Optimized High-Speed Performance: The lightweight nylon cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 7,000 rpm. The open design further enhances cooling and speed capability.
- Precision & Reliability: Manufactured with tight dimensional tolerances on the bore, outside diameter, and width, this bearing ensures consistent performance and ease of installation in precision assemblies.
- Material Integrity: Constructed from chrome steel for rings and balls, the bearing offers excellent wear resistance and durability, supporting a long operational lifespan.
