1206KJ Bearing Product Overview & Core Advantages
The 1206KJ is a metric double row angular contact ball bearing featuring a tapered bore design (1:12 ratio). Engineered for applications demanding high rigidity and precision, this bearing is designed to accommodate significant combined loads—handling both radial forces and axial loads in both directions simultaneously. Its compact bearing dimensions (30mm bore, 62mm OD, 16mm width) make it ideal for space-constrained, high-performance assemblies requiring reliable operation and long service life.
1206KJ Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a 1:12 ratio, enabling precise interference fit on tapered shafts for enhanced stability. |
| J | Designates the use of a steel cage, providing robust guidance for the balls and contributing to the bearing's high dynamic capacity. |
1206KJ Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact ball bearing construction delivers superior stiffness, effectively managing substantial combined radial and axial loads. This design ensures stable operation under demanding conditions.
Precision Tapered Bore: The 1:12 tapered bore allows for a controlled interference fit on mating shafts. This feature maximizes power transmission efficiency, minimizes fretting corrosion, and enhances overall system rigidity.
Optimized for High-Speed Operation: Manufactured from high-grade chrome steel for both rings and balls, and utilizing a durable steel cage, the 1206KJ is built for reliable performance at its limiting speed of 15,000 rpm.
Standardized Internal Clearance & Lubrication: Supplied with a standard CN radial internal clearance and pre-lubricated, the bearing is ready for immediate installation in a wide range of industrial applications.
