1219K Bearing Product Overview & Core Advantages
The 1219K double row angular contact ball bearing represents a premium precision bearing solution engineered for demanding applications. Featuring a tapered bore (1:12) and open construction, this bearing is specifically designed to handle significant combined loads, including radial forces and moderate axial loads in both directions. Its double row design provides enhanced rigidity and operational stability, making it an ideal choice for high-precision machinery requiring reliable performance. Pre-lubricated and manufactured with chrome steel components, it offers excellent durability and is ready for immediate installation.
1219K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Significance |
|---|---|
| 1219 | Standard bearing series designation |
| K | Tapered bore with 1:12 ratio |
The K suffix is particularly significant, indicating the tapered bore design that enables precise axial positioning and secure mounting on tapered shafts or adapter sleeves, ensuring optimal fit and performance.
1219K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact construction provides superior stiffness and enables the bearing to accommodate substantial radial loads and bidirectional axial loads simultaneously, making it suitable for applications with complex loading conditions.
- Precision Engineering: Manufactured with chrome steel rings and balls along with a stainless steel cage, the bearing ensures consistent performance, extended service life, and resistance to wear under demanding operating conditions.
- Optimized Internal Clearance: The standard CN radial internal clearance provides optimal performance for most industrial applications, balancing operational temperature and load conditions.
- Ready-to-Use Lubrication: Factory-pre-lubricated for immediate operation, reducing installation time and ensuring proper initial lubrication.
