Created 10/23/2007 - 22:46

The model 10R-606 has a clear axial aperture 6.06” diameter, and high radial capacity thanks to a large shaft. Originally designed for lens alignment, it offers ultra-high accuracy in an uncommon configuration, yet it shares the external dimensions of the standard model 10R.

Load capacity and stiffness are approximately linear with air pressure.

Ultimate load capacity is measured when metal-to-metal contact is made across the bearing surfaces. Working load capacity is half of the ultimate load capacity. Rotor weight must be included as part of total spindle load.

Axial and tilt loads are supported by the same bearing surfaces. Consequently, a load applied in one mode reduces the other mode proportionally.

High speed or high inertia applications require rotor containment. Maximum speed is dependent on application. Consult Professional Instruments for further information with regard to speed.
