O'Brien is Versatility

At O'Brien Gear Company, versatility is: 3 acres of state-of-the-art equipment, the best gear craftsmen in the midwest and our ability to machine, hob, shape, shave and grind any internal or external spline or gear imaginable.

We specialize in the work other companies can't handle -- especially work involving large diameter and deep, internal cut capacities.
