Precision Lead Screw Assemblies

Lead screw assemblies provide an economical solution for the transfer of rotary motion to linear motion. Berg is a pioneer in the development of lead screws; a cost effective solution to linear actuation problems. The close tolerance, free running nuts are ideal for miniature applications requiring rotary to linear or linear to rotary actuation.

Anti-Backlash Assemblies

For applications requiring precision positioning, Berg manufactures anti-backlash assemblies. This device, consisting of only three components, utilizes the constant force of a compression spring to push two nut halves apart. This action eliminates any play (backlash) which exists between the internal thread of the nut and the external screw thread. To ensure accuracy and repeatability the nut can be fine tuned through the use of the many available spring constants, to meet any pre-load design requirements.
