Founded in 1928, AIT originally supplied ball bearings to industrial customers. After a big sales slump in the mid-1980s, the company expanded its product line to include drive systems, rubber products, and fluid power components, allowing it to compete in a much bigger market.
It primarily sells these items through about 450 service centers throughout the United States, Canada, and Mexico. Customers include both the maintenance repair operations and
original equipment manufacturers. AIT also operates regional mechanical, rubber, and fluid power shops that perform services such as engineering design and conveyor belt repair.
