Smooth machinery operation with Skf bearings

Practical benefits

Dual direction load support: You handle both radial and axial loads simultaneously across bidirectional rotational movements with ease.
Low friction high speeds: The precision deep groove raceway lets you achieve high rotational speeds with minimal heat generation.
Robust cylindrical steel fit: The durable steel construction ensures you achieve a rigid and wear-resistant mount on standard shafts.

In a nutshell

The right choise for

With the Skf 6309 single-row deep groove ball bearing, you keep industrial machinery running smoothly and reliably. This open steel bearing with dimensions of 45X100X25 mm is designed to handle both radial and axial loads in either rotational direction. Thanks to its low-friction raceway design, you achieve high rotational speeds with minimal heat generation. The cylindrical bore and standard cn radial clearance enable a precise, secure fit on shafts across electric motors, gearboxes, and pumps. This allows you to carry out maintenance or overhauls quickly while extending the operating life of your equipment.
