H Box hollow-bore gearmotors include a 1-in. hollow output shaft that connects directly to driven loads. This saves space and eliminates shaft couplings, chains, or sprockets, as well as chain guards and hardware used to connect gearmotors to loads. In addition, the gearmotors feature chill cast-bronze gearing and heat-treated and ground-steel worms. Ratios are 10, 20, 30, and 60:1. They come in single and three-phase configurations.
