The MHT 150 N1 30 S20 1 0 2091 vane motor is produced by Vickers within the Vane Motors series and converts hydraulic flow into controllable rotation for automated machinery. Its theoretical displacement of 1852 cc per revolution supports high flow delivery, and the unit develops 203 Nm of torque for every 6.9 bar applied, giving designers a clear torque-pressure ratio. Continuous service is specified at 207 bar, while the assembly endures a stalled load up to 276 bar, defining safe pressure limits. When the circuit runs at 138 bar the rotor may reach 250 rpm, balancing speed with volumetric efficiency. Fluid enters through a 1.25-inch SAE four-bolt flange identified as port A and exits through an identical port B connection, creating a symmetrical flow path that eases hose routing.
The housing dimensions and fastening features support accurate installation. A body undercut diameter of 261.6 mm provides clearance for adjacent hardware, and a minimum straight diameter of 101.35 mm marks the narrowest shaft passage supported by the design. Sealing at the mount face relies on an O-ring with a 234.95 mm inner diameter, while a bolt circle measuring 298.5 mm positions the motor on its carrier plate. Six mounting holes tapped to .625-11 UNC-2B secure the unit, and a case drain port threaded .5625-18 UNF-2B returns leakage oil. Drain line back-pressure must stay below 1.7 bar to protect internal bearings, completing the installation data required for high-pressure hydraulic automation systems.
