Balancing Loberotor

Using our balancer, OIR's machinists can increase your up time and reduce your maintenance costs. We can balance your rotating elements to G specifications or to mil displacement. 

A selection of balancing arbors allows us to easily balance most rotating elements.

We are capable of balancing to G1 specifications.
Maximum running length in our balancer is 40ft.
Weight limits are, 250lbs minimum and 25,000lbs maximum.
