Gearboxes


Spur Gearboxes – Pittman spur gearboxes feature sintered steel gears to best compliment our offering of DC brush and brushless motors. These gearboxes are integrated directly with Pittman motors to offer greater flexibility to the design engineer. Spur gearboxes are offered with sleeve or ball bearings, optional lubricants for extreme temperature operation, and Delrin gears for reduced noise.

Planetary Gears – Pittman planetary gears are perfect for servo applications where maximum efficiency, minimum backlash, and a smaller mechanical footprint are necessary. In contrast to spur gears, planetary gears share the load through a pinion (sun gear) over multiple mating gears (planet gears). Planetary gears are offered with plastic or metal gears and sleeve or ball bearing outputs.
