Bosch Rexroth A2FM23/61W-VPB040 *GO2EU* axial piston fixed motor

A2FM23/61W-VPB040 *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 R902230023 has 23 cm³/rev nominal displacement and bidirectional rotation.

This execution has FKM seals, a parallel keyed shaft, a four-hole ISO 3019-2 mounting flange and threaded working connections at side and rear. 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.

The factory card records rear working port A as open. This does not imply that all alternative side and rear ports are open; connection status must follow the actual execution and installation drawing.

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.

The linked series data sheet lists a nominal pressure of 400 bar for this size, defined as maximum design pressure at the high-pressure working port A or B with mineral-oil fluid. Case pressure, boost pressure, speed, shaft load and duty restrictions still apply; this value does not establish a simultaneous pressure and flow operating point.
