A linear motion assembly (300, 500) including a component (302) having a longitudinal axis (104) and adapted to translate along the longitudinal axis, and a bearing (100) comprising a spiral body (102) including a substrate (112) and a low friction material (110), wherein the bearing (100) extends around the component (302, 502) and provides a low friction interface for translation of the component (302, 502), and wherein the bearing (100) 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 (100) is adapted to transition between the locked and unlocked conditions upon circumferential translation of an axial end (106) of the spiral body (102), longitudinal translation of an axial end (108) of the spiral body (102), or a combination thereof.
