DC Gearmotors Parallel Shaft
LEESON® offers parallel shaft dc gearmotors in a range of torques (10-1100 inch-pounds). Each gearmotor is precision machined in a pressure-cast aluminum gearbox to handle demanding environments requiring extended operation.
Our gearmotors are interchangeable with most major brand gearmotors, meeting the needs of commercial and industrial applications.
LEESON® parallel shaft dc gearmotors are available in our PZ Series, P300 Series, OS300 Series, PE350 Series, and P1100 Series designs.
