11212 Bearing Product Overview & Core Advantages
The 11212 metric double row angular contact ball bearing is engineered for applications demanding high rigidity and the ability to support substantial combined loads. Its double row design enables it to accommodate significant radial loads and bidirectional axial loads simultaneously, making it a compact and robust solution for high-precision machinery. Manufactured with chrome steel rings and balls, and featuring a nylon cage, this bearing is designed for reliable performance in demanding operational environments.
11212 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 11212 | Basic model number denoting a double row angular contact ball bearing with a 60mm bore, 110mm OD, and 62mm width. |
| Open (Seal Type) | The bearing is supplied without seals or shields, allowing for higher limiting speeds and is typically intended for systems with external lubrication. |
| Lubricated | The bearing is pre-lubricated from the factory, ensuring immediate operational readiness. |
| CN (Radial Clearance) | Specifies a normal radial internal clearance group, which is the standard for most general applications. |
11212 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized contact angle provide exceptional rigidity, enabling the bearing to handle high radial dynamic loads (7020 lbf) and combined loads effectively, making it suitable for applications with complex force conditions.
- Optimized for Speed: The lightweight nylon cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 3,400 rpm, qualifying it as a high-speed bearing for many industrial applications.
- Precision & Reliability: Manufactured from high-grade chrome steel with tight dimensional tolerances, this precision bearing ensures consistent performance, reduced vibration, and long service life.
- Ready-to-Use Convenience: The bearing is supplied pre-lubricated, facilitating easy installation and immediate operation without the need for initial greasing.
