What are the dimensions of this SKF ball bearing?

The bearing has an inside diameter of 45 mm, an outside diameter of 120 mm, and a width of 29 mm.

What does the C3 designation indicate?

The C3 clearance class means the bearing has a larger radial internal clearance than normal, suitable for higher thermal expansion or high speeds.

Is this deep groove ball bearing sealed?

No, this is an open bearing without seals, intended for external lubrication with oil or grease.

What loads can this bearing accommodate?

This single row deep groove ball bearing accommodates heavy radial loads and axial loads in both directions.

Dependable performance with Skf engineering

Practical benefits

Optimized for higher speeds: The C3 internal clearance ensures you avoid thermal binding when operational temperatures rise in continuous use.
Handles combined operational loads: Deep uninterrupted raceways allow you to absorb both radial and axial forces across bidirectional applications.
Smooth low friction rotation: Built from durable bearing steel, it minimizes vibrations so you achieve efficient operation with low maintenance.

In a nutshell

The right choise for

Keep your industrial machinery running smoothly with the Skf 6409/C3 single row deep groove ball bearing. Designed with increased C3 internal radial clearance, it reliably accommodates thermal shaft expansion during continuous high-speed operation, preventing jamming and excessive friction. Its deep uninterrupted raceways efficiently absorb both heavy radial and bidirectional axial loads. Featuring dimensions of 45X120X29 mm, durable bearing steel construction, and an open design suitable for external oil or grease lubrication, this bearing minimizes vibration and wear across electric motors, gearboxes, and drivetrain mechanisms.
