Our Machines

All of our balancing machines come equipped with a drive unit and HBI-25 balance indication system. The drive unit utilizes a hard-bearing suspension. The rotation of the part around its geometric axis causes centrifugal forces on the bearing pedestals of the machine. Piezo-electric measuring elements in the pedestals convert these forces into analogue alternating voltages. These voltages are electronically amplified and sensed by the HBI-25 to indicate the weight and angular position of the unbalance in the part.


REI® offers a complete line of manual, semi-automatic, & automatic balancing machines and dimensional measuring equipment as
well as a full suite of balancing and technical services.
