Bosch Rexroth A2FM Axial Piston Fixed Displacement Motor: Application, Service, and FAQ

1. Product Overview

The Bosch Rexroth A2FM series is an axial piston fixed displacement motor designed with an inclined-axis configuration for hydrostatic drives in open and closed circuits. It excels in both mobile machinery (e.g., construction equipment) and industrial applications (e.g., conveyor systems), offering high power density, compact size, and exceptional startup performance. Its robust design includes one-piece conical pistons with sealing rings, ensuring reliability under pressures up to 400 bar (peak 450 bar) .

2. Key Applications

• Mobile Machinery: Concrete mixer trucks, vibratory rollers, excavators, and road pavers .

• Industrial Equipment: Fixed installations such as pumps, compressors, and marine machinery .

• Specialized Uses: Drum drives for concrete agitators and winch systems .

3. After-Sales Service & Support

• Warranty: Standard 12-month warranty on parts and labor .

• Repair Services: Expert maintenance by certified technicians using OEM parts. Services include performance testing (pressure, flow, efficiency) on advanced hydraulic test benches .

• Global Supply Chain: Distributors in Europe, Asia, and North America ensure prompt delivery of original or certified aftermarket components .

• Technical Support: Customized solutions for retrofitting, system optimization, and troubleshooting .

4. Frequently Asked Questions (FAQ)

Q1: What hydraulic fluids are compatible with A2FM motors?

• Avoid HFA fluids. For HFB, HFC, HFD, or biodegradable oils, consult technical datasheets RC 90220–90223. Optimal viscosity: 16–36 mm²/s .

Q2: Can the A2FM be installed above the oil tank?

• Yes, but ensure the case is always filled with oil. For vertical mounting, consult the manufacturer .

Q3: How is output torque controlled?

• Torque increases with the pressure difference between high/low-pressure sides and displacement .

Q4: What is the lead time for orders?

• Small orders (≤20 units) ship within 1 day; bulk orders require ≤30 days .

Q5: Are aftermarket parts interchangeable with OEM?

• Yes, certified aftermarket parts match OEM form, fit, and function at lower cost .

5. Why Choose A2FM?

• Efficiency: High volumetric and total efficiency reduce energy costs .

• Durability: Reinforced components withstand harsh environments .

• Support: Global network provides 24/7 technical aid and lifecycle maintenance .
