Bosch Rexroth A6VM115HP1000000A/71MWV0P4Z92FV-S axial piston variable motor

A6VM115HP1000000A/71MWV0P4Z92FV-S, manufacturer material number R902226398, 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 hydraulic, positive.

The manufacturer’s RE91610 edition dated 29 January 2025 gives a standard base-motor geometric maximum of 115.6 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; pressure up to 530 bar is permitted for a limited 50 hours within that duty period. The base-motor speed limits are 3550 rpm at maximum displacement and 6150 rpm only below 69 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.
