A4VG280HT100RB0/40MLNE4T21U0000AE00-0R902199980

Axial piston pump Bosch Rexroth series A4VG, type code A4VG280HT100RB0/40MLNE4T21U0000AE00-0, material number R902199980. Nominal size: NG 280. Axial piston unit: swashplate design, variable, nominal pressure 450 bar, maximum pressure 500 bar (A4V). Operating mode: pump, closed circuit (G). Control device: hydraulic control, direct operated (HT1). Pressure cut-off: without pressure cut-off without bypass (0). Connector for solenoids: without connector (only for purely hydraulic control) (0). Swivel angle sensor: electric swivel angle sensor (DWS20-1, 3-pin) (R). Additional function: mechanical stroke limiter and stroking chamber pressure port X X (B). DA control valve (only for NG110 and 125): without DA control valve (0). Configuration of port and fastening threads: metric ports according to ISO 6149 with O-ring seal, metric fastening thread according to DIN (M). Direction of rotation: viewed on drive shaft counter-clockwise (L). Sealing material: NBR (nitrile rubber), shaft seal in FKM (fluoroelastomer) (N). Mounting flange: SAE J744 165-4 (E4). Drive shaft: splined shaft ANSI B92.1a–1976 2 in 15T 8/16DP (T2). Working port: SAE working port A and B, on left side (45° left) (1).
