Ball Screws

At Comptrol, our pre-engineered ball nut assemblies and end support options give you the opportunity to select from a wide variety of standard products to configure the right ball screw assembly needed to meet your specific design and application requirements.

Engineering and Manufacturing Services

We have the in-house engineering and manufacturing services available in order to meet your design requirements for non-standard ball screw / nut assemblies, ball screw support ends, and end machining.
