An anti-backlash nut includes a body having an axially-extending bore and internal threads for engaging a lead screw inserted into the bore. The internal threads are divided circumferentially into three inner segments each movable in a radial direction. The anti-backlash nut also includes springs for independently biasing the inner segments radially inward to contact the lead screw. The anti-backlash nut provides wear compensation as well as anti-backlash to improve positioning repeatability when used with an open loop positioner.
