1219 K/C3 Bearing Product Overview & Core Advantages
The 1219 K/C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This precision bearing features a tapered bore (1:12) and is pre-lubricated for immediate use. Its double row design enables it to support significant combined loads, including radial and axial loads in both directions, making it exceptionally versatile. With a C3 radial internal clearance, it is well-suited for applications involving thermal expansion or where interference fits are used, ensuring reliable performance under demanding conditions.
1219 K/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1219 | Basic bearing designation, indicating the bearing dimensions (95mm bore, 170mm OD). |
| K | Denotes a tapered bore with a 1:12 ratio, designed for precise mounting on adapter sleeves or withdrawal sleeves. |
| C3 | Indicates a greater than normal radial internal clearance, ideal for applications with expected thermal expansion or heavy interference fits. |
1219 K/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides superior stiffness and enables the bearing to handle substantial combined radial and axial loads simultaneously.
- Tapered Bore Design: The 1:12 tapered bore allows for precise axial positioning and secure clamping on a shaft, ensuring a tight fit and minimizing slippage.
- Optimized Cage & Lubrication: The nylon cage contributes to smooth operation at the limiting speed of 5000 rpm. The bearing is pre-lubricated for immediate startup and reliable initial operation.
- Material & Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability and a long operational lifespan under the specified temperature range of -30°C to 110°C.
