Smooth rotation with Skf 6406

Practical benefits

Heavy load support: You accommodate high radial and axial forces in both directions thanks to the deep groove geometry.
Low friction operation: The open design minimizes rolling resistance, allowing you to achieve efficient high-speed rotation.
Easy cylindrical mounting: Featuring a standard 30 mm bore, you install this single-row bearing directly onto compatible machinery shafts.

In a nutshell

The right choise for

Ensure smooth rotation and dependable power transmission with the Skf 6406 single-row deep groove ball bearing. Engineered from durable steel with a 30 mm cylindrical bore, 90 mm outside diameter, and 23 mm width, this bearing accommodates heavy radial loads and axial forces in both directions. The open design and standard normal radial clearance (CN) deliver minimal frictional resistance at high rotational speeds in lubricated machinery, such as electric motors, gearboxes, and industrial drive systems. It allows you to replace worn bearings quickly and keep your equipment running quietly and efficiently.
