1222/C3 Bearing Product Overview & Core Advantages
The 1222/C3 is a double row angular contact ball bearing designed for applications requiring high radial load capacity and operational stability. This precision bearing features an open design and is pre-lubricated for immediate use. Its key advantages include the ability to handle significant combined loads, high rigidity due to its double row construction, and a generous C3 radial internal clearance suitable for applications with thermal expansion or misalignment. Built from high-grade chrome steel, it ensures durability and reliable performance in demanding industrial environments.
1222/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Standard bearing designation indicating a double row angular contact ball bearing with a 110 mm bore and 200 mm outside diameter. |
| /C3 | Specifies a radial internal clearance greater than normal (C3 group). This is beneficial for applications involving thermal expansion, high speeds, or where fits result in a reduction of internal clearance. |
1222/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide high radial stiffness, enabling the bearing to support substantial radial dynamic load ratings of 19890 lbf and resist operational deformations.
- Optimized for Demanding Conditions: The specified C3 clearance ensures reliable performance under thermal gradients or misalignment, preventing binding and reducing friction.
- Durable Construction: Components made from chrome steel (rings and balls) and a stainless steel cage offer excellent resistance to wear and corrosion, contributing to a long service life.
- Ready-to-Install: The bearing comes pre-lubricated, simplifying installation and providing immediate protection upon startup.
1222/C3 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery, including:
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery
- General Industrial Machinery requiring robust and reliable support
