1219 K Bearing Product Overview & Core Advantages
The 1219 K is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing is engineered to accommodate combined loads, meaning it can simultaneously support significant radial loads and axial loads in both directions. Its compact design, featuring a double row of balls, provides high rigidity and rotational accuracy, making it an ideal choice for machinery requiring high reliability and precise operation. The open design and high-quality materials ensure consistent performance within a broad operating temperature range.
1219 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1219 | Standard bearing designation indicating the bore diameter (95 mm) and series. |
| K | Denotes a tapered bore with a taper of 1:12. This allows for precise axial adjustment and secure mounting on an adapter sleeve or withdrawal sleeve. |
1219 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to handle substantial combined loads (radial and bidirectional axial loads) effectively.
- Optimized for Precision: Manufactured with Chrome Steel rings and balls, this bearing ensures high dimensional stability and long-term precision. The Nylon cage is lightweight, contributing to smooth operation at high speeds.
- Conical Bore Advantage: The K-suffix tapered bore allows for micro-adjustment of internal clearance during mounting, enabling optimal preload for the application. This feature is critical for achieving maximum system rigidity and accuracy.
- High-Speed Capability: The combination of the open design, high-grade steel, and lightweight cage supports a limiting speed of 5000 rpm, qualifying it as a high-speed bearing for many industrial applications.
1219 K Bearing Typical Application Areas
The 1219 K bearing is widely used in applications requiring high precision, rigidity, and the ability to handle complex loads. Key industries and equipment include:
- Machine Tool Spindles
- Gearboxes and Transmission Systems
- Vibrating Screens and other Mining Equipment
- Agricultural Machinery
- Pump and Compressor Shafts
