Sumitomo Parallel Shaft Screw Conveyor Drives

Sumitomo Helical BuddyBox (HBB) combines the quiet, efficient, and reliable performance of the Cyclo input with the robust helical gear output, creating a compact and flexible solution for a wide range of output speeds and torque requirements. The HBB design provides a simple splash lubrication system that extends the unit’s lifespan and operates without thermal limitations, eliminating the need for an external fan. Sumitomo offers durable, high-performance solutions for reliable operation with minimal maintenance.

The parallel shaft design of the HBB gearmotor is the most common type of gearmotor used on a screw conveyor. This design is cost-effective and matches the height and width of most screw conveyors more closely than other drive arrangements. The HBB design does extend the overall length of the conveyor when compared to a right-angle gearmotor such as the Sumitomo BBB gearmotor, or a belt or chain driven system. Sumitomo offers a wide variety of mounting options, including a CEMA standard screw conveyor adaptor, for seamless integration into virtually any application. HBB gearmotors are available with space-saving integral motors or c-face adapters that allow for a wide variety of third-party motor options.
