Shop Gear Motors

A hydraulic gear motor consist of multiple gears, typically one driving gear and one idler gear, enclosed in a housing. Pressure will force the gears to rotate, 

generating torque. Most gear motors are available in either aluminum or cast iron flanges, and are  in one of the three groups below. 

The higher the motor group, the larger the displacement and body size. There is some overlap in sizing between groups, so if your application does not meet the

speed requirement or isn't as robust as you'd prefer, you may go up one group size to find a better-suited motor. All OneHydraulics gear motors
offered online are birotational, although unidirectional units are available upon request. 

Lower pressure rating, more economical, most common

Higher pressure rating, more robust, slightly more expensive
