Linear Motion Solutions

linear-motion-headerMistequay Group is a leading manufacturer of custom designed, precision ballscrews for both commercial and military aerospace. Our staff is dedicated to the design and manufacture of world class aerospace ballscrews. Mistequay fills the niche of offering unmatched service coupled with exceptional on-time delivery. Our engineers are available to assist with anything from a clean sheet new design and/or integration to the optimization of existing designs to the production of legacy designs. We offer accurate load and life analysis coupled with expert material and heat treat options. Involving Mistequay at the earliest stage of the design will pay large dividends in the long haul. Our team will put forth the most optimized, cost-effective solution to fulfill your most complex linear motion application. By involving our team early in the process, our engineers can identify key cost drivers and potential technical pit-falls along with lead-time obstacles. In addition to design engineering, we also offer FAA-PMA Approval Process support along with complete reverse engineering services coupled with Repair & Overhaul consultation.

Our engineers are able to apply 65+ years of application experience and market knowledge to solve your most complex design challenge. Mistequay design engineers utilize both Siemens NX® and Dassault Systemes’ CATIA® with analysis backed by NASTRAN® Finite Element Analysis software.

Mistequay’s ballscrew manufacturing is housed within our state-of-the-art AS9100 manufacturing facilities equipped with the latest machine tool and metrology equipment. Our ballscrew facility is equipped with CNC thread grinders, staffed by machinists with 30 years of manufacturing experience. Our manufacturing facility focuses on complex, high-mix, highly-processed products in low to medium-sized releases, thereby making ballscrews a very integral part of our product portfolio.

Efficiency Testing

Mistequay’s assembly and testing laboratory is a clean and modern facility, staffed with experienced assembly/ testing technicians. Our PLC controlled Bauer efficiency stand can actively measure efficiency down the entire stroke of the assembly, complete with chart plotting. Our maximum capacity is 6000 pounds of tension and compression with a maximum speed of 1200 RPM. Our test stand measures both tension and compression efficiency in real time, along with the ability to measure axial lash at various positions along the screw axis. Mistequay can also test and measure back-driving efficiencies including torque testing, both loaded and unloaded, while also measuring break-away torque.
