Eliminating backlash from lead screw nut designs has always been a demanding task. To eliminate the backlash often meant a sacrifice in drag torque. With some innovative nut designs, our standard anti-Backlash lead nuts are available for use with several standard thread forms. The anti-backlash nut ranges feature compensation for clearance or wear between the leadscrew and nut when reversing the direction of movement. 

Our standard Plain leadnuts are suitable to be used on several thread forms. By matching the nut to the screw increases accuracy and reduces the stresses within the driven system.

We strive to ensure a precision fit tolerance between the nut and screw to ensure a more reliable linear movement. In some cases we utilise a PTFE impregnated plastic as the nut base which gives excellent wear, high load capacity and a high degree of structural integrity . Plain nuts are available for both right handed and the left handed threads.
