1219-K-M-C3 Bearing Product Overview & Core Advantages
The 1219-K-M-C3 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing features a tapered bore (1:12) and is pre-lubricated for immediate use. Its core strength lies in its ability to handle significant combined loads, including high radial forces and moderate axial loads in both directions. The double row design provides superior high rigidity, making it ideal for applications requiring precise shaft positioning and minimal deflection. With its optimized internal geometry and brass cage, it offers reliable operation and long service life.
1219-K-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| K | Tapered Bore (1:12) | Allows for precise axial adjustment and secure interference fit on tapered shafts, enhancing stability. |
| M | Brass Cage | Provides high strength and excellent guidance for the balls, suitable for high-speed operation and demanding conditions. |
| C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion in applications with higher operating temperatures or heavy loads, preventing premature failure. |
1219-K-M-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction enable this bearing to support high radial loads and bidirectional axial loads simultaneously. This results in a highly rigid support system that minimizes shaft runout and maintains accuracy under combined loads.
- Optimized for Performance: The brass cage (M) ensures smooth ball guidance and is capable of withstanding the stresses of high-speed operation, contributing to the bearing's limiting speed of 5000 rpm. The open seal design minimizes friction, further supporting its speed capability.
- Pre- lubricated & Ready for Use: Delivered pre-lubricated, the bearing is immediately ready for installation, reducing setup time. The specified temperature range of -30°C to 110°C ensures performance across a wide spectrum of industrial environments.
- Precise Engineering: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and wear resistance. The precise bearing dimensions and C3 clearance provide reliable and predictable performance.
