Construction

The balls within the nut are re-circulated by the use of a return tube after completing from 1.1/2 to 3.1/2 turns (nut type dependant). Again depending on the nut type there may be one or more circuits.

Features

There are two types of external geometry for the tube type.

• Circular bore fitting - where the circulation parts are housed within the circumference of the nut.
• Projected tube type - where the circulation parts are outside the nut circumference allowing for a reduced nut size.

Types

• Small axial play, flanged, return tube, single nut
• Oversize ball preloading, flanged, return tube, single nut
• Lead offset preload, flanged, return tube, single nut
• Spacer preloaded, flanged (on one nut), return tube, double nut
• Spacer preloaded, flange to flange, return tube, double nut

Other versions and combinations can be requested although they may be special production items.
