The 26M42A 1C20 hydraulic motor belongs to the Vane Motors series and is manufactured by Vickers for use in automated fluid power systems where rotational output is required. A balanced vane cartridge distributes pressure evenly, and the rotor carries ten vanes to stabilize flow and speed. Heavy-duty support is provided by a ball bearing in the body and a bushing in the cover, a layout that manages both radial and axial loads. Bidirectional rotation lets the motor drive machinery in either direction without mechanical changes. A Teflon ring serves as the interport seal to prevent leakage between pressure and return chambers, and design number 20 identifies the specific internal configuration used in this model.
The cover contains an external drain port so excess case oil can return directly to tank, and the port is arranged in line from cover to body to streamline hose routing. Circuit fluid enters and leaves through an SAE 4-bolt flange, while an SAE 2-bolt mounting flange fastens the motor to equipment frames. The cam ring withstands up to 42 in-lb of torque for every 100 psi applied, defining its mechanical limit during pressure spikes. These features combine to give the 26M42A 1C20 predictable installation points, controlled internal leakage paths, and reliable torque delivery in industrial hydraulic drives.
