Smooth rotation with Skf reliability

Practical benefits

Dual direction load support: You effortlessly accommodate both radial and axial loads across demanding mechanical assemblies.
Increased C3 internal clearance: The C3 radial clearance ensures you maintain smooth running properties when temperatures and speeds increase.
Low friction steel design: High-grade bearing steel delivers quiet operation and reduced vibration throughout extended machine cycles.

In a nutshell

The right choise for

With the Skf 6406/C3 single row deep groove ball bearing, you ensure reliable, smooth rotation across demanding industrial machinery. Featuring a 30 mm cylindrical bore, a 90 mm outside diameter, and a 23 mm width, this robust steel bearing accommodates both radial and axial loads in both directions. The increased C3 internal radial clearance prevents binding during thermal expansion and high-speed operation in electric motors, gearboxes, and pumps. Built with an open design suited for external lubrication or oil bath systems, it minimizes friction and vibration so your equipment runs consistently with less downtime.
