Established in 1976 as a manufacturer of carbon brush holders, BGB began exporting in the early 1990s - now over 90% of turnover is achieved through the exportation of rotary goods and services such as slip ring assemblies, fibre optic rotary joints and other rotary transmission devices.

Specialising in the design from concept, manufacturing, and marketing of niche engineering solutions, the company prides itself on developing quality rotary assemblies.  With two sites in Grantham (UK) and a second plant in Virginia (USA), BGB has built a great reputation for its products worldwide. Predominant European markets include Scandinavia, Spain, and Germany in which BGB lays claim as the market leader of rotary solutions in the renewable energy sector, primarily within the wind industry.
