Acme Screws

The RBS line of ACME screw products has been designed and manufactured to provide an economical means for converting angular/rotational motion to linear/translational motion.

The RBS standard line of ACME screws are produced to General Purpose-2G tolerances from excellent quality materials. The following technical information section will start by describing RBS ACME nomenclature, followed by illustrating and defining basic ACME thread terminology, and finish with technical design definitions, constraint parameters, and mechanical equations that govern safe screw operation and selection.
