A heavy-duty, precision fixture for realistic training in shaft alignment. Designed based on the dimensions of a common ANSI centrifugal pump, the device allows for training using all common alignment techniques and tools. Each element can be adjusted to create unique alignment problems. The training aid, coupled with a textbook and a Use/Exercise Guide, creates a complete, in-depth, hands-on course in precision alignment techniques used in industry.
7-Gauge, formed-steel baseplate.
Heavy-duty, welded aluminum driver and driven elements.
Allows for alignment using all common methods and alignment tools.
Dimensions based on a common ANSI centrifugal pump.
Rigid construction allows alignment to .001".
Requires a minimal number of hand tools.
Flanged bearings allow changes in angular and parallel misalignment.
