Smooth rotation with Skf reliability

Practical benefits

Low friction at high speeds: You achieve quiet and efficient operation at high rotational speeds thanks to the low-friction deep groove design.
Bidirectional load handling capability: You accommodate both radial and axial loads in either direction smoothly without needing complex multi-bearing assemblies.
Compact fit for tight spaces: With a 6 mm bore and 13 mm outer diameter, you easily mount this component in confined mechanical spaces.

In a nutshell

The right choise for

With the Skf 618/6 single row deep groove ball bearing, you ensure smooth and dependable rotation in compact mechanical systems. Thanks to its low-friction design, this steel bearing runs quietly and efficiently at high rotational speeds while accommodating radial and axial loads in both directions. Featuring a 6 mm bore, 13 mm outside diameter, and 3.5 mm width, it is ideal for tight spaces, precision instruments, and model making. The cylindrical bore and standard radial internal clearance (CN) allow straightforward mounting on matching shafts, helping you eliminate play and keep miniature drive mechanisms running at peak performance.
