About Us

SG Transmission began life in 1972 and has, since then, been designing and manufacturing electromagnetic clutches and brakes for its global customer portfolio. Fundamentally an engineering business, we provide innovative solutions for specific market or customer requirements through our in-house design team.

Our manufacturing facilities were purpose built to meet the existing and future capacity demands of the business and the capability for large or small volume orders. We continue to invest in the latest CNC machinery to improve efficiency and have a clear focus on continuous improvement in lean and efficient cellular manufacturing.
