Dynamic Load (Ball Screws)
Dynamic load rating is the maximum load which a ball bearing screw assembly can maintain for 1.0 million inches of travel (Inch Series) or 1.0 million revolutions (Metric Series).
Design Load (Lead Screws and Glide Screws™)
Maximum load at which a lead screw assembly should be operated. Not applicable for life calculations.
The nominal outside diameter of the screw shaft for a screw only. For a nut it is the nominal outside diameter of the mating screw.
The axial distance a nut travels from one revolution.
The direction of threads on a shaft or in a nut. Left hand means that the nut will move away if rotated counterclockwise. Right hand means the nut will move away if rotated clockwise.
The axial free motion between the nut and screw is called backlash. An Ant-backlash nut is designed to reduce or eliminate this movement.
Lead Screw
The lead screw assembly converts rotary motion to linear motion. The lead nut slides over the thread of the screw. Thomson lead screws excel in applications which require the “just right” solution.
Ball Screw
The ball screw assembly converts rotary motion to linear motion with recirculating ball bearings. Ball screws have a very low friction coefficient and is typically greater than 90% efficient.
Glide Screw™
Part linear bearing, part lead screw, the Glide Screw™ from Thomson combines the best features of these products into an easy to install, one-part solution.
