Large Bore and Close Tolerance Bearings for Gear Drives | American Roller Bearing

Almost all heavy industries world-wide use gear drives to reduce the high shaft speed of a prime mover to a usable R.P.M.  American's large bore and close-tolerance roller bearings are installed in many large, heavy-duty gearing arrangements.  Huge gears are necessary to turn the large shafts, that do everything from flattening out metals in the rolling mills to moving the launch crawler for the space shuttle.

Bearings We Offer

American Roller Bearing primarily makes heavy duty bearings that are used in various industries in the US and around the world. Not only must our industrial class bearings provide long in-service life from a rolling fatigue criterion, but they must also hold together structurally from impacts, overloads and occasional high speed excursions. The design of every heavy duty bearing has been optimized to this end, including our large bore bearings.
