1211 C/2 Bearing Product Overview & Core Advantages
The 1211 C/2 is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to handle combined loads. This precision bearing efficiently supports substantial radial loads and axial loads in both directions simultaneously. Its compact design, featuring a 55 mm bore and 100 mm outside diameter, makes it an ideal solution for space-constrained, high-reliability machinery. Manufactured with chrome steel components and a nylon cage, it delivers excellent performance and durability in demanding environments.
1211 C/2 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 1211 | Basic bearing designation indicating the bearing size (55 mm bore, 100 mm OD, 21 mm width). |
| C | Specifies the radial internal clearance group. In this case, it corresponds to the standard CN clearance. |
| /2 | Indicates that the bearing is lubricated with a specific grease suitable for the standard operating temperature range. |
1211 C/2 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity, enabling the bearing to withstand significant combined loads (radial and bidirectional axial loads) without compromising performance.
- Optimized for Performance: The lightweight nylon cage ensures smooth operation and contributes to the high limiting speed of 9,000 rpm, making it suitable for high-speed applications.
- Precision & Reliability: Manufactured from high-grade chrome steel with tight dimensional tolerances, this bearing ensures consistent performance and long service life in precision machinery.
- Ready-to-Install: The bearing is pre-lubricated, simplifying installation and providing immediate operational readiness within its specified temperature range.
1211 C/2 Bearing Typical Application Areas
This bearing is engineered for use in a wide range of industrial equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
