Rexroth A2FM80 61W-VUDN027-S Axial Piston Fixed Displacement Motor 100% New Original

Product Description:

1. Advantages and Features

High power density and efficient transmission

Adopting the oblique axis axial piston design, the power-to-weight ratio is optimized, and high-pressure output (continuous working pressure can reach 25MPa) is achieved in a compact structure, which is suitable for heavy-duty industrial scenarios; The transmission efficiency is stable, and the output torque is linearly related to the pressure difference and displacement, which supports precise speed regulation (by adjusting the pump flow or motor displacement).

Reliability and long-life design

Integrated plunger + plunger ring structure, with hardened alloy steel gear, strong wear resistance, significantly extended service life (long-life bearing optional model); The drive shaft bearing is specially strengthened to withstand axial/radial loads, and the vibration and noise control is better than similar products.

Flexible adaptation and dynamic response

Support open-loop hydrostatic transmission, modular interface compatible with servo motors and hydraulic pumps (such as A10VSO series), simplifying multi-system integration; Fast dynamic response, excellent starting characteristics, small swing torque, suitable for high-precision walking machinery and industrial equipment. ‌

Easy maintenance and energy-saving features‌

The grease seal design reduces maintenance frequency, and the maintenance cycle can reach more than 10,000 hours;
The optimized oil absorption characteristics reduce energy loss, and the total system efficiency is increased to more than 90%.

2. ‌Precautions for use‌

‌Installation and commissioning specifications‌

It is necessary to ensure that the motor and the drive equipment shaft are concentrically connected, and the flange bolts are symmetrically tightened to avoid excessive radial load (chain drive requires a flexible coupling);
Before the first start, it is necessary to fill and exhaust, and gradually pressurize and debug to prevent instantaneous high-pressure impact from damaging the seal.

‌Operating environment and medium management‌

The cleanliness of the hydraulic oil must meet the NAS 1638 level 6 standard, and the oil contamination must be monitored regularly (it is recommended to be tested every 500 hours);
The operating temperature range is -10~80℃. In high temperature environments, a heat dissipation device must be configured or high-temperature resistant sealing materials (such as fluororubber "V" seals) must be selected.

‌Load and operation limits‌

It is forbidden to operate over rated torque (such as the maximum continuous pressure of 25MPa for the A6VM series). Long-term overload can easily lead to gear breakage or bearing failure;
Avoid frequent start-stop and sudden load changes to prevent the planetary gear set from being subjected to impact loads.

‌Maintenance and parts replacement‌

When replacing seals or bearings, original parts (such as long-life bearings with "L" marks) must be used to ensure compatibility and wear resistance;
Before long-term shutdown, the residual oil must be drained and anti-rust oil must be injected to prevent oxidation and corrosion of internal components.

‌Key tips‌:

When multiple motors are linked, the synchronization parameters must be calibrated through the PLC to avoid the accumulation of motion deviations;
When using environmentally friendly hydraulic oil (such as HFD/HFB/HFC type), the medium must be matched according to the requirements marked on the nameplate.
