Check points for design (5) Overall length of flange inner bore should contact with shaft. Adjust the coupling overall length center position with center of both shafts distance. Then tighten set screws to fix flanges on both shafts. After coupling fixed onto shafts, check the dimension (S) at several points of unit inner end face. If there are some difference at several points, there would be possibility of parallel & angular misalignment. It would be strongly recommended to adjust alignment of 2 shafts again. ■ Important points to note for ball screw feeding system In servo motor driven ball...

Semi-assembled design by flanges, spacer unit & bolts reduce assembling time. SFU is new partially designed metal disc coupling (flanges, spacer unit & bolts) that enable quick compared with existing parts distribution type.(model:SFS) Assembling/disassembling without assemble/disassemble moving both side shafts improve productivity significantly. We’ve launched both single element & more flexible double elements type to meet the diverse assembly needs of customers. Semi-assembled unit design with High torque, Ultra-High stiffnes SFU has both single & double elements unit semi-assembled precisely...

Standard Bore-Drilling reference table Check points for design Refer to below table for bore drilling specification of keyway with set screw type. SFU-070-140DS Models compliant with the old JIS standard (class 2) JIS B 1301 1959 ■ Special points to take note You should note the following matters to prevent any problems at end users. (1) Be sure to keep permissible mis-alignment of parallel, angular, and axial figures. (2) Be sure to tighten bolts with specified torque. SFU model is delivered by 4 kind of parts(Flanges, Unit, Assembling bolts,Set screws) Unit is assembled with high accuracy by...
