The ISB ball transfers comprise a large, tempered ball bearing which sits on 100–200 smaller balls with minimal frictional resistance. They are available as pressed and moulded units for light loads and precision machined for heavy loads; the border line between the two is 500kg.

Made from a variety of advanced composites – including scratch-free DuPont Vespel, PBI and PEEK for handling glass substrates – the electrically conductive ISC Series has been developed specifically for clean room and hygienic production.
