Abstract
A linear motion assembly including a component having a longitudinal axis and adapted to translate along the longitudinal axis, and a bearing comprising a spiral body including a substrate and a low friction material, wherein the bearing extends around the component and provides a low friction interface for translation of the component, and wherein the bearing is adapted to prevent longitudinal translation of the component in a locked condition and permit longitudinal translation of the component in an unlocked condition. In an embodiment, the bearing is adapted to transition between the locked and unlocked conditions upon circumferential translation of an axial end of the spiral body, longitudinal translation of an axial end of the spiral body, or a combination thereof.

A linear motion assembly comprising:
- a component having a longitudinal axis and adapted to translate along the longitudinal axis;
- and
- a bearing comprising a spiral body including a substrate and a low friction material, wherein the bearing extends around the component and provides a low friction interface for translation of the component, and wherein the bearing is adapted to prevent longitudinal translation of the component in at least one longitudinal direction in a locked condition and permit longitudinal translation of the component in an unlocked condition.
A bearing for a linear motion assembly, the bearing comprising:
- a spiral body comprising:
- a substrate;
- and
- a low friction material coupled to the substrate,
- wherein the bearing is adapted to extend around a component and is selectively lockable, and wherein in a locked condition the component is prevented from longitudinal translation in at least one longitudinal direction.
