FC Cylinders PC Cylinders BF Cylinders of standard type. Cylinders having mounting dimensions conformed to JIS standard. SC Cylinders TC Cylinders Super Cylinders with Rod guided by Linear ball bearing prove absolute minimum of friction. Thin Space-saving type of Diaphragm Cylinders facilitate high precision control of pressure force. LC Cylinders Large-sized TC Cylinders Thin type Double Action Cylinders of small bore with non-sealed twin rod reveal ultra low sliding friction The large-type TC series air cylinder features a large output capacity through rolling of a BF diaphragm, providing highly accurate output control. The installed height is minimal because the cylinder is very thin, which assists in delivering highly accurate pressing control. Fujikura BF cylinder has a unique structure which uses an original thin diaphragm.
