Precision machine parts are manufactured by applying the precision processing technology of ISSOKU, an expert in precision measurement. The “side contact” type that uses the spiral structure of a screw and the “rolling contact” type that has a rapid and light movement and enables accurate positioning through the use of a ball between the screw shaft and a nut, these products have an active role in various machine tools, semiconductor production equipments and aircraft and contribute to a wide range of industry. This is part of the results of long-term accumulation of technology by ISSOKU and highly precise processing technology.

Floating unit for Ball screw (Custom-made)
 


Error such as run out of nut end face, alignment error, lead error due to shaft whirling will be extremely reduced by X-Y axis floating joint mechanism. As pitching error, yawing error and rolling error can be extremely reduced, it’s best for precision feed mechanism. As joint of floating unit is composed by steel ball and harden shaft and assembled with preload, there is no backlash in lead direction. High mechanism in compact body and space-saving compared with old type using plate spring. We will design to meet your installation apace. Please consult us by all means.
