Inch Twin-Lead Acme Screw Assembly, 1 1/2", 4 Turns Per Inch, 1 Starts, Bronze Nuts

Twin-Lead acme screws offer dual opposing motion using a single drive system. These one-piece high performance acme screws are made from high alloy steel that is black oxided for protection and can be assembled with Nook PowerAc™ acme nuts, flanges and EZZE-MOUNT™ bearing supports to form cost effective systems.. Twin-lead acme screws can be used in molding machines, packaging equipment, food processing machinery, robotics, material handling equipment, tire manufacturing and assembly applications.

Twin-Lead screws stocked for delivery without machined ends are listed in the chart below. To order a twin-lead cut to a custom length and/or with machined ends, select a size from the chart below, determine OAL, LH and RH thread length, nut, flange and, if required, EZZE-MOUNT™ bearing support.
