Ball transfers allow the smooth and effortless movement of loads in any direction. Newly added to the R. A. Rodriguez engineering components range, 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 500 kg. 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. They are already used in flat panel and photovoltaic production lines and also in electronic and pharmaceutical manufacture Asia-wide. Custom ball transfers are also available.
