1222-M-C3 Bearing Product Overview & Core Advantages
The 1222-M-C3 is a double row angular contact ball bearing engineered for demanding industrial applications requiring superior rigidity and the capacity to handle significant combined loads. Its double row ball construction provides enhanced stability and load-carrying capability compared to single row designs, making it an optimal solution for machinery where high precision and operational reliability are paramount. This bearing is pre-lubricated and features a generous C3 radial internal clearance, making it particularly suitable for applications with thermal expansion or where interference fits are used.
1222-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
- 1222: Basic designation indicating a double row angular contact ball bearing series with a 110 mm bore and 200 mm outside diameter.
- M: Designates a brass cage (machined window-type). This cage offers excellent strength, stability, and guidance at high speeds.
- C3: Specifies a radial internal clearance greater than the standard CN group. This is essential for applications involving thermal expansion, heavy interference fits, or where a reduction in operating temperature is desired.
1222-M-C3 Bearing Structural Features & Performance Benefits
The performance of the 1222-M-C3 is a direct result of its robust construction. The double row design significantly increases the bearing's rigidity, minimizing shaft deflection under heavy radial loads and moderate axial loads in both directions. The use of a machined brass cage (M) ensures smooth operation and stability at the bearing's limiting speed of 4,300 rpm. The C3 internal clearance provides operational flexibility, preventing excessive preload and heat buildup in challenging mounting conditions. Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers long-lasting performance and high dynamic load capacity.
1222-M-C3 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery where high load capacity and rigidity are critical. Common applications include:
- Gearboxes and power transmission systems
- Heavy-duty pumps and compressors
- Industrial electric motors
- Material handling equipment and conveyor systems
- Various types of rolling mills
