Straight Talk On Leadscrews

Reliable leadscrew applications depend not only on proper selection, but also on correct installation and alignment to eliminate off-axis load. Ball Screws & Actuators Co. A self-aligning, single-rail stage has rail and screw locating pockets machined in one operation allowing the assembly to be installed without adjustment. A vertically floating lead nut compensates for misalignment and prevents binding. High-precision, twin-rail stages use a fixed reference rail to align a parallel floating rail. The preloaded ground ball screw floats perpendicular to its axis in two directions during assembly.

Industrial Pins
Industrial pins are varieties of fastening hardware meant to couple, align, mount, assemble, or penetrate two workpieces. The operation of the pin depends on design and employment, but industrial pins can be categorized into several categories, such as: hitch and linch pins; cotter pins and wire clips; spring pins; locating and fixturing pins; and specialty pins.
Lead Screws and ACME Screws
Lead screws and ACME screws are used to drive a nut in linear motion via direct contact between the screw and the nut. Lead screws usually incorporate proprietary screw and nut geometries and materials, and can be configured in zero-backlash arrangements.
Linear Slides and Linear Stages
Linear slides are simple linear motion devices composed of a stationary base and a moving carriage. Linear stages are slides with a drive mechanism that provide controlled, precise positioning along a linear axis.
Ball Screws
Ball screws convert rotary motion to linear motion, or torque to thrust, and vice versa. They are primarily a power screw with a train of ball bearings riding between the screw and the nut in a recirculating track.
Locating and Fixturing Pins
Locating and fixturing pins are press-fit, removable hardware devices designed to align or affix two work pieces to very small tolerances. When translation mechanisms are not stable or precise enough to place objects in position for a particular process, locating and fixturing pins can ensure an accurate alignment.
