Ball Screws - Mounting assembly
Installation Instructions
The ball screw assembly should be mounted into a system or machine as shown in the figures below. Axial loading of the nut is optimal for performance and life and side loading installations or applications should be avoided.

Typical ball screw installations are combined with linear slides to
provide support and guidance. Linear rails and ball screws must then be
aligned parallel to prevent binding, increased system torque and a
decrease in life. Typical installation practice consists of “floating”
the ball screw or the linear rail into alignment. To “float” a screw
into alignment, secure the linear rail into position and adjust the mounting blocks or nut to minimize the error from parallel.
