Bosch Rexroth A2FM23/61W-VAB020 *GO2EU* axial piston fixed motor

A2FM23/61W-VAB020 *GO2EU* is a Bosch Rexroth A2FM series 61 fixed-displacement axial piston motor with a bent-axis rotary group for open and closed hydraulic circuits. Factory article R902230021 has 23 cm³/rev nominal displacement and bidirectional rotation.

This execution has FKM seals, a splined shaft, a four-hole ISO 3019-2 mounting flange and SAE flange working connections on opposite sides. It has no integrated pressure-relief valve or speed sensing. The factory card identifies case drain T1 as plugged on delivery; the installation instructions determine which drain connection must be used.

Nominal size is distinct from exact geometric displacement. Admissible speed, pressure and shaft load depend on the applicable fluid, case-pressure, inlet/boost-pressure and duty conditions. Family maxima are not assigned as universal simultaneous operating ratings.

For nominal size 23, the series sheet specifies 400 bar nominal pressure at the high-pressure working port A or B for hydraulic fluids based on mineral oils. This is the series maximum design pressure, subject to the stated case and shaft-seal pressure, inlet-pressure and duty restrictions; it is distinct from the limited-duration maximum pressure.
