Ball screws and acme lead screws pair with corresponding threaded nuts to convert rotary motion into linear motion. Precision ball screws provide accurate positioning in a compact size. Precision ball nuts attach to precision ball screws to create a linear motion system. Precision lead screws with nuts convert rotary motion into linear motion through integrated flange nuts. Ball screw flanges and end blocks connect to ball screws for mounting and support. Acme screws carry high loads and are suited for vertical applications. Acme nuts pair with compatible acme screws to construct linear motion systems. Acme flanges and end blocks connect to acme screws and nuts as part of an acme screw system.
