The AA10FM23/52W-VCC66N000 piston motor is produced by Bosch Rexroth as part of the A10FM Piston Motors series for hydraulic automation where compact high-power rotary actuation is needed. Its displacement of 23.5 cm3/rev determines the fluid volume moved per revolution and assists in flow calculation for circuit design. The motor supports alternating rotation, enabling bidirectional operation without additional valves. At nominal conditions it accepts 115 l/min of inlet flow to match medium-size pump outputs. Continuous duty at 280 bar allows it to drive cylinders and hydrostatic transmissions that require elevated working pressure. Under this pressure it can absorb 53.6 kW of mechanical input, giving adequate power density for industrial machines. A top speed of 4900 rpm broadens the usable range for variable speed prime movers. The tapered keyed shaft with a threaded bolt provides secure torque transfer while simplifying coupling alignment. FKM sealing withstands common hydraulic oils and elevated temperatures to maintain leak-tight performance.
The unit tolerates peak system surges up to 350 bar, so short overloads in pressing or lifting equipment do not damage the rotating group. A starting torque of 75 Nm at 280 bar guarantees dependable breakaway under load, and at maximum displacement it produces 105 Nm for low-speed tasks that need higher torque. The shaft end handles axial forces up to 1000 N, while a radial limit of 1200 N supports belt or gear loads without premature bearing wear. An internal case volume of 0.6 l stores return oil to aid lubrication and heat removal. The drain connection uses a 3/4-16 UNF-2B thread according to ISO 11926, simplifying attachment of standard return lines. Service ports for pressure flow are supplied with a 1 1/16-12 UN-2B thread conforming to the same standard, ensuring compatibility with common high-pressure hoses.
