The sleeves are generally manufactured to ‘GO’ gauge dimensions with each tooth expanding radially from the true centre to locate on either pitch, major or minor diameters. This makes them ideally suited to machining or inspecting other features from the centre line axis of the spline.

The Splined arbor illustrated is ‘power’ actuated from the machine drawbar and features a ‘wobble’ plate backstop to ensure that a drive coupling is machined true to the spline axis. As with all Acugrip products machine spindle adaptors can be supplied.
