Electromagnetic clutches and brakesInnovative drive technology and power transmission solutions

Electromagnetic solutionsSG Transmission has been designing and manufacturing electromagnetic clutches, brakes and holding magnets since 1972. With a commitment to innovation, we offer a customised design service to deliver the best solution to our global customer base.

Manufacturing for the futureWe continue to invest in the latest CNC machinery, automation and testing facilities and we have a clear focus on continuous improvement in lean cellular manufacturing. Our purpose built factory enables us to cater for large and small volume orders from all over the world.

Experienced design engineersOur experienced in-house design team work alongside our customers to develop solutions to meet specifi c holding forces, space requirements or develop new innovations. We provide a full project management service from design to manufacture and test.

Quality engineeringWe place a strong focus on process measurement and control using our quality management system. By creating a strong focus on continuous improvement, we exceed our customer’s quality expectations in the most highly demanding market places. We hold internationally recognised certifi cates such as ISO 9001, OHSAS 18001 and ISO 14001.

Part of a global engineering groupSG Transmission is part of the British Engines Group, which employs over 1,500 people within its seven engineering businesses. It has offi ces in 16 countries across the world including Australia, USA, India, South Africa, Singapore and Germany. We benefi t from the core services and people orientated culture of our parent company, which includes taking on apprentices as part of the British Engines Apprenticeship Scheme, as well as graduates.
