MHT 460 250/210 N1 30 S19/20

The MHT 460 250/210 N1 30 S19/20 is a hydraulic vane motor built by Vickers within the Vane Motors series. It converts pressurized fluid energy into controlled shaft rotation for hydraulic automation circuits. Bidirectional operation permits the shaft to turn either clockwise or counter-clockwise, allowing designers to reverse motion without additional valving. When the supply pressure reaches 100 psi, the full-torque setting delivers 460 lb-ft to move heavy loads. A mid-torque selection provides 250 lb-ft at the same pressure for medium duty cycles.

A third low-torque mode produces 210 lb-ft at 100 psi for light loading conditions. The three torque modes let a single motor satisfy varied duty points without changing displacement hardware. The case drain port is rated for a maximum back-pressure of 1.7 bar (25 psi), so return plumbing must hold this limit to prevent seal damage. ISO 18/15 or cleaner fluid cleanliness is required to protect vane surfaces and extend service life. These conditions support consistent performance when the motor is integrated into closed-loop or open-loop hydraulic systems.
