25M42

The 25M42 hydraulic motor is part of the Vickers Hydraulic Accessories series from Vickers and serves as a rotary actuator for automated hydraulic circuits. It uses a vane motor design to convert pressurized fluid into steady shaft rotation, and its displacement is 43.9 cm³ per revolution (2.68 in³ per revolution), which establishes the volume of oil moved each cycle. When driven at 1200 rpm it passes 52.6 L/min (13.9 gpm), supporting moderate flow requirements in machine tools and material handling equipment. The housing accepts 4-bolt flange port connections so the unit can be fastened directly to rigid manifolds without adapters. A ring torque rating of 42 lbf-in per 100 psi (4.7 Nm per 6.9 bar) defines the moment that can be transmitted through the internal rotor ring under typical system pressures.

The motor withstands a maximum pressure of 175 bar (2500 psi), allowing it to operate in high-duty industrial power units while maintaining internal clearances. Shaft rotation is permitted up to 4000 rpm, giving adequate speed range for indexing tables or auxiliary drives that require rapid cycling. A rated dry weight of 18 kg (40 lb) informs lifting guidelines during installation and aids in calculating frame loads in mobile equipment. Together, the pressure capability, speed limit, and mass data define the operating envelope for designers integrating the 25M42 into hydraulic automation systems that demand compact size, reliable torque delivery, and stable performance under continuous service.
