Bosch Rexroth A2FO 32/61R-VBB06 – High-Efficiency Bent Axis Pump

The Bosch Rexroth A2FO 32/61R-VBB06 represents the pinnacle of fixed displacement pump technology. Engineered with a bent-axis rotary group, this Series 61 pump offers a distinct advantage over swashplate designs by delivering higher power density in a smaller, more angular envelope. It is specifically calibrated for open circuit hydrostatic drives where consistency and durability are paramount.

This model is configured with a clockwise rotation and high-quality FKM (Viton) seals, ensuring resilience against high operating temperatures and aggressive hydraulic fluids. Its proven tapered piston design simplifies the rotating group, providing a rugged solution that withstands the heavy vibrations and shock loads typical of commercial vehicles and heavy construction equipment.

Key Features & Benefits

• Bent-Axis Technology: The 40° bent-axis design minimizes dead volume, resulting in exceptional volumetric efficiency and self-suctioning characteristics.

  High Power Density: Delivers maximum power output relative to its compact weight and size, freeing up valuable space on mobile equipment chassis.

• Robust Sealing System: Equipped with FKM (Viton) seals (Code V), providing superior resistance to high temperatures and chemical degradation compared to standard NBR seals.

• Easy Integration: Features a parallel keyed shaft (DIN 6885) and an ISO 4-bolt mounting flange (Code B), making it a standard, easy-to-replace component for existing systems.

• Threaded Port Connections: The rear threaded ports (Code 06) ensure secure and leak-free hydraulic line connections without the need for complex flange blocks.

Common Applications

The A2FO 32/61R-VBB06 is a versatile powerhouse commonly found in:

• Commercial Vehicles: PTO (Power Take-Off) applications on trucks for tipping gear and cranes.

• Construction Machinery: Hydraulic power sources for concrete mixers and mobile pumps.

• Forestry Equipment: Harvesters and forwarders requiring reliable flow in harsh outdoor conditions.

• General Hydraulics: Stationary industrial power units requiring fixed flow at high pressures.
