Bosch Rexroth A8V86 — axial piston pump 86 cm³
Bosch Rexroth A8V86 is a variable displacement axial piston pump with a bent-axis design, engineered for operation under maximum load conditions in heavy construction and road machinery.
Bosch Rexroth A8V86 is the successor to Uchida Hydraulics pumps, which were used for decades in leading construction equipment. Following the integration of Uchida Hydraulics into the Bosch Rexroth group in the 1990s–2000s, the A8V series received an expanded technical base and broader application across global special machinery.
The A8V86 pump is used in crawler and wheeled excavators, road machinery, construction equipment and hydrostatic machine drives. Compatible with equipment from leading global manufacturers: Hitachi, Daewoo, Hyundai, Doosan.
