Customized ground ball screws of single nut type and double nut type using End-deflector method
(FR series) with range of small diameter 15mm-40mm are available.
Moreover, those of JIS C3-C7 grade accuracy can be manufacture.
The range of screw shafts that can be manufactured to meet each accuracy
grade of customized ground ball screws is shown below:
When the slenderness ratio (shaft length per shaft diameter) is large,
it is sometimes difficult to manufacture a ball screw with the desired
accuracy.
The following table shows the maximum length of screw shafts of each
accuracy grade that can be manufactured in the standard process.
When ball screws exceeding the manufacturable range are required,
