W.M. Berg is a pioneer in the development of lead screws. W.M. Berg is committed to providing cost effective solutions for linear actuation problems. Because of the close tolerance, the free running nuts are perfect for small applications that require rotary to linear, or linear to rotary, actuation. W.M. Berg also manufactures Anti-backlash nuts for applications that require precision positioning. These anti-backlash nuts have only three components and utilize constant force from a compression spring to push the two nut halves apart. Because the force is constant, the action eliminates any backlash (free axial movement between the screw and the nut) which may exist between the internal thread of the nut and the external screw thread. W.M. Berg has manufactured the anti-backlash nuts to be fine-tuned through the use of multiple available spring constants to meet any pre-load design requirements. The ability of these nuts to be fine-tuned ensures accuracy and repeatability, which is important for your applications.

A lead screw assembly is a screw and nut device used to transmit motion or power, instead of fastening. We offer high quality lead screw assemblies, and our expert technicians and engineers will ensure you are getting the highest quality lead screw assembly. As with all W.M. Berg precision manufacturing parts, lead screw assemblies are customizable to your needs. W.M. Berg knows that load requirements are an important factor to consider before properly adding a lead screw into a design. When possible, nuts should be positioned to be pulling the load, or so as to be put in tension. This positioning of nuts eliminates the need for buckling considerations. W.M. Berg, one of the world’s largest and most reliable manufacturers of precision parts provides quality and value through our lead screw assemblies.
