The Top of Rexroth's A4VG Displacement Range
The A4VG280 sits at the largest-displacement end of the A4VG family, specified for the heaviest mining and construction equipment classes where maximum travel-drive power is required from a closed hydrostatic circuit.
At this displacement class, the A4VG280 is a genuinely specialised part — used on the largest mining excavators and heavy construction equipment rather than standard-size machines. Given the scale of equipment this serves, confirming your exact machine and requesting a tolerance-verified unit matters more than usual; WhatsApp us your machine details and, ideally, a nameplate photo before ordering.
| Machine | Type | Pressure | Displacement |
|---|---|---|---|
| Large mining excavators | Mining / Heavy Construction | 400 bar | 280 cc/rev |
| Heavy construction equipment | Construction (travel drive) | 400 bar | 280 cc/rev |
