1222 K/C3 Bearing Product Overview & Core Advantages
The 1222 K/C3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high radial load capacity and precise operation. Featuring a tapered bore (1:12) for secure shaft mounting, this precision bearing offers exceptional rigidity and stability. Its open design, pre-lubricated for immediate use, and C3 radial internal clearance make it suitable for applications with thermal expansion considerations, ensuring reliable performance under combined loads.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Basic bearing designation indicating bearing dimensions: 110 mm bore, 200 mm OD, 38 mm width. |
| K | Denotes a tapered bore with a 1:12 ratio for precise interference fit mounting. |
| /C3 | Indicates greater radial internal clearance than normal (C0), suitable for applications with shaft expansion or high operating temperatures. |
1222 K/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides superior radial load carrying capacity and enhanced system stiffness compared to single row designs.
- Precision Tapered Bore: The 1:12 tapered bore ensures a tight, secure fit on the shaft, minimizing slippage and maintaining positional accuracy under heavy loads.
- Optimized Cage Design: The nylon cage contributes to smooth operation, lower friction, and is suitable for the bearing's limiting speed of 4,300 rpm.
- Pre-Lubricated & Ready-to-Use: Factory-applied lubrication allows for immediate installation and operation, reducing maintenance downtime.
- Wide Temperature Range: Constructed from chrome steel, the bearing operates reliably in temperatures from -30°C to 110°C.
1222 K/C3 Bearing Typical Application Areas
This bearing is engineered for robust performance in various industrial sectors, including:
- Industrial Gearboxes and Transmissions
- Material Handling Conveyor Systems
- Agricultural Machinery
- Vibrating Screens and Machinery (benefiting from the C3 clearance)
- Pumps and Medium-Duty Electric Motors
