GH Series Heavy-Duty Horizontal Gear Motor – High-Torque Models, Shaft Sizes & Ratios

The GH series is the heavy-duty counterpart to the CH series, featuring a more rigid cast iron housing and enhanced bearing support for higher shock loads and continuous heavy-duty operation. It retains the same foot-mounted horizontal configuration but offers greater durability.
