  • Choosing the Best Lead Screw for a Linear Motion Application
    Getting the best lead screw for the job Knowing the details of a linear-motion application increases the odds of choosing the right ball screw. Before engineers can specify the type and size of leadscrew needed for a linear-motion application, they must understand the demands of that the job
  • Kerk Lead Screws Help Diamong Analyzer Achieve Dazzling Accuracy (.pdf)
    . Without this precision, the device's accuracy. would certainly be called into question.". Playing an integral role in the motion system's meticulous performance is a lead screw. assembly from Kerk Motion Products, one of the world's premier manufacturers of non-ball lead. screws located in Hollis
  • Which Screw? Picking the Right Technology
    each type of screw. design will be detailed later in the following sections. To provide an overall understanding of screw selection, it. is first necessary to define common screw terminology and. explain the different types of screws. 3. Screw Terminology. Lead ­The linear distance of travel
  • Selecting and Sizing Ball Screw Drives
    The selection of the correct ball screw assembly for a specific. application is an iterative process that determines the smallest envelope and most costeffective. solution. The design load, linear velocity, and positional accuracy are used to. calculate the diameter, lead and load capacity
  • About Ball Screws
    of the balls when they are in contact with the ball screw and ball nut races. The axial distance the screw or nut travels in one revolution. (Accuracy) The difference between the actual distance traveled compared to the theoretical travel based on the lead of the screw. The lead error for a standard screw
  • Precise moves depend on ball-screw threads
    a combination of the three methods in an effort to lower cost, raise production, or boost device accuracy. Often, both manufacturers and end users focus only on lead accuracy and compare it to permissible position error. This is a simple and, in most cases, insufficient approach. How a screw is manufactured
  • New Spins on Bearing Technology (.pdf)
    Nook Industries provides a complete selection of inch and metric Ball Screws, Roller Screws, Acme Screws, Lead Screws, End Bearing Supports, Precision Locknuts, Worm Gear Screw Jacks, Electric Actuators, HRC 60 Linear Shafting, Linear Bearings and Pillow Blocks to the Linear Motion Industry
  • Using Thermography to Find a Class of Latent Construction Defects in Drain and Vent Pipes
    An issue that continues to plague the construction industry, nails and screws coming into contact with copper water pipes, can be diagnosed with infrared thermography. A leak may not immediately occur, but galvanic action between the steel fastener and the copper pipe will eventually lead to a hole
