Profile: The Precision Alliance manufactures miniature linear actuators, shaft couplings, linear motors, ball screws and linear roller guides. We supply a range of slides, positioning tables, and stages for linear and rotary motion using ball screw, lead screw and linear motor drives. We deal with purchasing, machining and assembling of various components. We offer high speed gantry systems, and high accuracy granite based metrology positioning systems for the semiconductor & electronics industry. Reli-a-Flex® couplings dramatically reduce transmission errors that minimize velocity and positional fluctuations, & eliminate the breakage that is so often seen in high cycle applications using typical spiral beam couplings.
