Caged Ball ProfileRail Installation


To ensure the linear guide is precisely assembled with your machined table, Nook machines a recess in the reference edge corner. The corner of the machine table must be smaller than the chamfer of the linear guide to avoid interference.


The standard length of rail is 4 meters, Nook provides jointed rail solutions. The joint number will be laser marked on the rail.

1. Follow the joint number to assemble. (Shown in FIG. A)

2. When having two or more rails running in parallel that have buttjoints, Nook suggests setting the joints in different positions between master and slave rail to avoid the change in accuracy. (Shown in FIG.B)

3. Follow the recommended tightening torques to fasten the screws from inside out.
