  • Acme Screw VS Ball Screw: Which to Choose?
    when choosing between acme screws and ball screws is the materials used to create these assemblies. Since an acme screw is a simpler mechanism, comprising of the screw and nut, it can be made from materials like bronze or plastic. When plastic nuts are used, there is less of a need to lubricate
  • Selecting a Lubricant for Ball Screws and Acme Lead Screws
    lubricity and reduce friction when properly formulated with gelling agents and base oils. Specifying a lubricant. Acme lead screws with bronze or polymer nuts have higher friction and greater wear than ball screws and proper lubrication plays a vital role in performance and increased life. Even
  • Ball Screw vs. Lead Screw
    screw type to use in a linear motion stage, one. must understand “what is” a ball screw and lead screw. A ball screw runs on ball bearings;. more specifically, a screw and nut that have matching helical grooves that allow ball bearings to. recirculate in those grooves. The grooves, or races
  • A Critical Look at Acme, Ball, and Roller Screws for Linear Motion
    actuators: Acme, ball, and roller. The differences are in thread shape and the design and operation of the matching nut. But which type of screw best suits your application? Here's a concise look at all three. screws use strong threads with generally trapezoidal teeth which are usually rolled onto
  • Which Screw? Picking the Right Technology
    that these nuts may add friction to. the system. 6. Acme screws are available in a wide variety of diameters and. leads to match application requirements. A metric version of. the acme screw is also available and commonly referred to as. a trapezoidal screw. Although the tooth shapes are very. similar
  • Selecting and Sizing Ball Screw Drives
    . The features of bal screws in. relation to other linear actuation devices are summarized in the following table: Hand Actuation. Low cost, slow speed. Acme Screw. Low cost, moderate. speeds, multiple positioning. Air cylinder. Single position, moderate. loads, can be costly if you. don't already have air
  • What You Ought To Know About Ball Screws
    as small as 0.375-in. diameter and 0.125-in. lead with 90% efficiency. (Acme screws are typically just 30 to 60% efficient.) Single-nut screws have 170-lb dynamic load capacity and 1,600-lb static load capacity. Load capacities double when using two nuts. The next time you're faced with a design
