Engineering The Glide ScrewTM is designed to actuate a moment load or a side load without additional linear guidance or support. Therefore, the screw deflection is the determinant feature and the following charts must be used when properly sizing a Glide Screw for an application. How the Glide Screw Works The unique design of Glide Screw allows it to handle axial, radial and moment loads without additional guidance. The result is an efficient and space saving design that is quick and easy to install with reduced maintenance needs compared to traditional solutions. axial load axial load...

Glide Screw Engineering Moment Load and Radial Load Charts Determine your end support configuration and then use the following charts to properly size the nominal diameter of the Glide Screw. Select a product diameter that lies above and/or to the right of the design moment or load. The lead of a Glide Screw is defined as the axial distance traveled for one revolution of the screw. Select the appropriate lead of your screw based on the desired speed and resolution of travel. Note that the Glide Screw is limited to 300 RPM. Inch Diameter Models 250 Moment load [in-lbs] Metric Diameter Models...

IBTHOMSON• Linear Motion. Optimized." Installation Comparing Alternative Technologies The Glide Screw™ is both drive system and linear guide, so these features are already perfectly aligned and cannot bind. Therefore, installation is simple and the mating components do not require high tolerance geometric features. Drive and Guide Technology Comparison

Glide Screw Installation Basic Installation Guidlines The success of the Glide Screw in an application is primarily dependent on the end support configuration. Since the Glide Screw is a combination of a lead screw and linear bearing, the ability to handle non-axial loads while maintaining positional accuracy is the key to a successful installation. The load capacity curves are based on screw deflection and not the lead nut capacity. Therefore, stiffness of the assembly determines load capacity. Select end support configuration A fixed bearing support should be selected when possible. A...
