Driven nut unit AME

The threaded nut is supported by an axial-contact thrust ball bearing ZKLF...2Z. The preferred type is the downgraded PE version. The bearing is preloaded as defined with a series HIR slotted precision nut. The O-shape arrangement of the two lines of balls makes for high tilting rigidity. Any axial and radial forces are borne without problems. The thick-walled stable outer ring of the bearing is screwed directly to the bearing block. No additional bearing bushing or bearing cover is used.

The oil-circuit lubrication supplies the bearing with lubricant. The ballscrew nut is lubricated via a radial bore in the spindle. For the downgraded axial-contact thrust ball bearing, only axial lubrication is possible. A broad range of realized applications makes the perfect basis for solving your problem. Standard installation of the ZKLF bearing as shown with the extraction slot in the direction of the toothed belt wheel. Installation in reversed order is possible upon request.
