Product Overview: The QJ 212 Four-Point Contact Ball Bearing
The QJ 212 is a specialized single-row Angular Contact Ball Bearing, specifically a four-point contact type, with principal dimensions of 60mm bore diameter, 110mm outer diameter, and 22mm thickness. This bearing is ingeniously designed to accommodate axial loads in both directions, making it an excellent space-saving solution. Its unique raceway geometry allows a single bearing to function similarly to a pair of single-row angular contact bearings mounted back-to-back or face-to-face. The inner ring is typically split, which facilitates easy mounting and dismounting of the bearing components.
As a leading supplier of industrial components, we provide high-quality QJ 212 bearings manufactured to precise industry standards. These bearings are essential for applications where axial space is limited but high bidirectional axial load capacity is required. They can also support radial loads, offering a versatile solution for complex load scenarios in various industrial machinery.
Key Features of the QJ 212 Bearing
- Four-Point Contact Design: Engineered to support high axial loads from both directions with a single bearing unit.
- Space-Saving: The compact design replaces the need for two separate bearings, saving significant axial space on the shaft.
- Bidirectional Axial Load Capacity: Capable of managing thrust loads in two directions, simplifying machine design.
- Split Inner Ring: Allows for easier assembly and disassembly, reducing maintenance time and complexity.
- High Rigidity: Provides strong and stable support for rotating shafts under combined load conditions.
- Durable Construction: Manufactured from premium-grade bearing steel for superior durability and a long operational lifespan.
