Schaeffler bearings in Sauer-Danfoss pumps

4th Quarter 2010 Hydraulic systems & components

New generation of hydrostatics.

The overall efficiencies of the H1 pumps and H1 motor from Sauer-Danfoss have been increased by the optimised X-life cylindrical and tapered roller bearings supplied by Schaeffler.

In developing the H1 series, as well as optimising and improving the electro-hydraulic system itself, Sauer-Danfoss also focused on optimising the base components within the hydraulic pumps and motors. Schaeffler’s new X-life cylindrical roller bearings with optimised rib contact have made an important contribution to these design improvements.

The special curvature of the roller end faces improves the contact geometry between the roller end faces and the bearing ribs, minimising contact pressures. This enables the formation of a load carrying lubricant film where roller end faces and ribs are completely separated by the lubricant. The rollers now slide on the lubricant film under axial load. This means that the new cylindrical roller bearings can operate with a much higher axial load to the radial load ratio. At the same time the frictional torque is up to 50% lower, depending on the magnitude of the axial load. The benefits are lower operating temperatures, higher efficiency and reduced energy consumption.

The Sauer-Danfoss range of H1 pumps and motors is built around an advanced electrical control and is available in a wide range of displacements. Designed for high and medium power needs, H1 offers higher output speeds, lower input speeds and a reduced total installed lifecycle cost.
