Tandem Paired Double Angular Contact Ball Bearings

Pair-mounted angular contact ball bearings can bear radial and axial bidirectional combined loads dominated by radial loads, and can also bear pure radial loads. The tandem configuration can only handle axial loads in a single direction, while the other two configurations can handle axial loads in either direction. This type of bearing is generally selected and combined by the manufacturer and submitted to the user. After installation, there is preload interference, and the ring and steel ball are in an axial preload state, thus improving the rigidity and rotation of the entire set of bearings as a single support.

precision.

In a back-to-back configuration, the rear-mounted designation is DB (such as 70000 C/DB), and the load lines of the bearings paired back-to-back are separated toward the bearing shaft.

Face-to-face configuration, the rear code is DF (such as 70000C/DF), and the load lines of the face-to-face paired bearings converge to the bearing shaft.

In series configuration, the rear code is DT (such as 70000C/DT). In series configuration, the load lines are parallel, and the radial and axial loads are evenly shared by the bearings.

In the realm of high-performance machinery, managing combined loads is a fundamental challenge. Our Angular Contact Ball Bearings are engineered specifically to meet this demand, offering exceptional operational stability and longevity. The unique design of these bearings features raceways in the inner and outer rings that are displaced relative to each other along the bearing axis. This allows them to support significant radial and axial loads simultaneously, a capability that sets them apart from standard deep groove ball bearings. The contact angle is key to their performance, enabling superior rigidity and precision in applications where shaft deflection must be minimized.

The versatility of our Angular Contact Ball Bearings is evident in their wide range of applications across critical industries. They are the component of choice in high-speed machine tool spindles, robust agricultural machinery, and precise robotics. Their ability to handle high axial loads in one direction makes them ideal for gearboxes, pumps, and compressor systems. Furthermore, these bearings can be arranged in tandem, back-to-back, or face-to-face configurations to support higher loads or moment loads, providing engineers with flexible solutions for complex design challenges. This adaptability ensures that our bearings deliver optimal performance, enhancing the efficiency and reliability of the entire system.

We are committed to delivering products that exceed industry standards. Every Angular Contact Ball Bearing in our catalog is manufactured using premium-grade steel and undergoes rigorous quality control and testing. From the precision grinding of the raceways to the meticulous assembly of the cage and balls, no detail is overlooked. The result is a bearing that guarantees high running accuracy, exceptional speed capability, and a dramatically extended service life. For applications demanding unwavering precision and durability, our Angular Contact Ball Bearings provide the trusted foundation your designs require.
