Acme and Lead Screw
Acme lead screws and high performance Acme nuts are combined to provide the optimum performance available in this type of lead screw. The highly burnished surface finish of the acme lead screws and low friction bronze and plastic acme nuts yield a smoother, less abrasive action than conventional cut Acme screws or lead screws.
