1222-K-M-C3 Bearing Product Overview & Core Advantages
The 1222-K-M-C3 is a double row angular contact ball bearing designed for applications requiring exceptional rigidity and the ability to handle combined loads. Featuring a tapered bore for precise mounting on adapter sleeves or withdrawal sleeves, this precision bearing offers high reliability in demanding industrial environments. Its open design, pre-lubricated state, and C3 radial internal clearance make it suitable for applications with thermal expansion considerations, ensuring stable performance under varying operational conditions.
1222-K-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Basic bearing designation: 110 mm bore, 200 mm OD, 38 mm width. |
| K | Tapered bore (1:12 ratio) for secure mounting on adapter sleeves. |
| M | Brass cage, providing high strength and excellent guidance at high speeds. |
| C3 | Greater than normal radial internal clearance, ideal for applications with thermal expansion or where interference fits are used. |
1222-K-M-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to accommodate significant combined radial and axial loads from both directions, making it ideal for heavy-duty applications.
- Precision Tapered Bore: The K-designation tapered bore ensures a tight, slip-free fit on a tapered shaft seat or adapter sleeve, crucial for maintaining precision and concentricity.
- Optimized High-Speed Performance: The machined brass cage (M) ensures stable operation and guides the balls effectively, contributing to the bearing's limiting speed of 4,300 rpm.
- Operational Reliability: The bearing is pre-lubricated and features an open design, which, when combined with the C3 clearance, provides a robust solution for applications with thermal gradients and ensures long service life.
1222-K-M-C3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Heavy-duty Pumps and Compressors
- Paper Mill Machinery and rolling mill applications
- Agricultural and Construction Machinery
