RBC Bearings' Heim Unibal® ball bearings offer ability to handle loads to such applications as wheels, casters, ammunition loaders, textile machines, door closers, power tools, conveyors, wheelchairs, pulleys, and lift mechanisms. Heim's manufacturing process produces races uninterrupted by splits or slots. While Heim ball bearings are unground, their burnished races provide smooth operation, which may allow a Heim design to be used in place of precision ground bearings in many applications. Unibal® bearings are available in plain, flanged OD, and extra capacity to allow clevis mounting. They are offered in all the standard bearing sizes, plus special configurations.
