ABSTRACT:
A low friction traveling nut assembly carried on a threaded spindle for linear movement therealong in response to rotation of the spindle about its rotational axis includes a housing, a roller rotatably mounted within the housing by roller bearings, and a clutch mechanism which engages when the spindle is rotated in one direction relative to the traveling nut assembly to effect substantial sliding friction between the roller and a bearing surface reacting with the housing so that the traveling nut assembly is automatically braked to resist movement in one axial direction.
