The AA10VG45HD3D1/10L-NSC60F045D-S axial piston unit belongs to the A10VG Variable Piston Pumps series and is produced by Bosch Rexroth for hydraulic automation tasks. The pump delivers 46 cm³ of displacement per revolution to convert shaft rotation into fluid flow, while an integrated boost stage adds 8.6 cm³ to keep the main inlet charged during high demand. The hydrostatic design supports a nominal working pressure of 300 bar for consistent actuator force. When operated at that pressure the rotating group supplies 220 Nm of torque and can transmit up to 75.9 kW to the hydraulic system. Continuous duty is permitted up to 3300 rpm, and short bursts can reach 3800 rpm without exceeding mechanical limits, whereas the drive must not fall below 500 rpm to maintain lubrication.
Peak circuit events are accepted up to 350 bar to handle transient loads in the same machines. At the maximum speed and full displacement the pump provides a flow of 152 l/min so that cylinders and motors can work at rated velocity. Speed changes are further bounded by a limited value of 3550 rpm which acts as an electronic or mechanical cap between continuous and intermittent regions. Fluid temperature may rise to 115 °C before thermal derating is required, and the housing holds 0.75 L of oil to bathe the bearings and swashplate. The assembly weighs 27 kg without a through drive option, and its rotating parts exhibit a moment of inertia of 0.0033 kg·m², a figure relevant for drive sizing during acceleration. A permissible axial shaft load of 1500 N allows belt or gear couplings to apply reasonable thrust without damaging the bearings.
