Bosch Rexroth A6VM280EP200P000E/71MWV0S4A22VV-S axial piston variable motor

A6VM280EP200P000E/71MWV0S4A22VV-S, manufacturer material number R902556860, is a Bosch Rexroth A6VM series 71 bent-axis variable-displacement hydraulic motor for open and closed hydrostatic circuits. The factory catalogue identifies this complete execution. Its control is proportional electric, positive.

The manufacturer’s RE91610 edition dated 29 January 2025 gives a standard base-motor geometric maximum of 280.1 cm³/rev and nominal working-port pressure 450 bar with mineral-oil hydraulic fluid. At full swivel (100% swivel angle and geometric maximum displacement), the 500 bar duty limit uses individual operating periods up to 10 seconds and a cumulative 300 hours; the size 280 limit remains 500 bar. The base-motor speed limits are 2500 rpm at maximum displacement and 3550 rpm only below 118 cm³/rev, with optimum viscosity 16–36 mm²/s and the stated inlet-flow and load conditions.

The actual supplied minimum displacement, control presets and suffix-specific geometry are not established by the catalogue identity. Use the binding installation drawing for exact shaft, flange, port and accessory details. These qualified series limits are not unconditional ratings for a complete customized assembly.
