Product Description:

The 121.20.584.00 hydraulic gear motor is produced by Danfoss as part of the MCD Soft Starters series. While the electronic starter controls the AC supply, this motor delivers the hydraulic rotation needed for clamps, conveyors, or rotary actuators inside automated cells. By linking the electric and fluid-power sections of a line, the component supports smooth acceleration of loads that must be driven by oil rather than by direct electric torque.

The volumetric displacement is 8.4 cm³/rev, so each revolution moves a fixed oil volume that scales motor torque with pressure. At a permitted ceiling of 4000 rpm, the unit can reach a theoretical flow of 33.6 L/min, matching medium-capacity power packs. Continuous service is rated to 250 bar, which aligns with the stated outlet back-pressure limit and defines the shaft power envelope. Oil enters through a 13.5 × 30 × M6 port and leaves via an identical outlet; a 1/4 G drain port returns case leakage to tank and protects seals. Four mounting bolt holes and a 36.5 mm flange pilot center the housing precisely on manifolds or gearboxes.

The minimum operating speed of 700 rpm ensures hydrodynamic lubrication during slow cycles, while a peak pressure of 280 bar can be accepted for brief overloads such as pressing or indexing strokes. Bidirectional rotation allows a single unit to drive forward and reverse movements without circuit changes. Installation weight is only 2.5 kg, easing maintenance, and the shaft uses a 1:8 taper locked by a M12 × 1.25 thread for repeatable coupling alignment.

Wake Industrial can arrange same-day shipping for urgent orders, provides international shipping options for global facilities, and keeps quotations valid for 30 days so that budgeting cycles remain predictable.
