NSK Standard Ball Screws High-Speed SS Series

Interchangeability Installation dimensions are the same as those of a conventional SS series

Compact By improving the nut manufacturing technology, highly precise screw manufacturing is
possible with the long nut.
Achieved high-level stiffness and high load capacity equivalent to that of double nut
preload by changing the double nut preload to the offset preload of a single nut, and
compact sized nut.

lSeal

Adopted thin seals axially and shorten nut length

Convenience l‌Optional configurations are possible for ball screw length as
well as for the shaft end design

The blank shaft ends can be customized according to customers' requests. See page
11 in NSK's recommended design when drawing up plans for a shaft end. The support
units are available on pages 12-14 in the case of NSK's recommended design.

lNew support unit: For high speeds and heavy loads

The support unit is applied for the thrust angular contact ball bearing, TAC series, with
high precision and rigidity. NSK design is available attached to the support unit, which
easily constitutes a system.

lOil supply

2 oil holes, M6×1.0, are provided in the nut flange periphery and the end of the nut
flange.
A plug is standardly screwed into the periphery of the nut flange.
