Typical Applications
Turbochargers, AC servo motors, high-speed spindles, gyroscopes, blower/sirocco fans, automotive parts, and rotating parts
in general
(1) Standard machines include one standard bearing. Cost estimates for special bearings are available on request.
(2) The minimal achievable residual unbalance will vary with the workpiece weight and the test speed. Refer
to the attached sensitivity diagram for details.
(3) Depending on the form and weight of the workpiece, the test speed may be increased beyond the specified
range.
(4) Drive systems other than upward-tangential drive systems are available on request.
Note: Specifications and appearance are subject to change without notice.
