Rexroth A2FM A6VM hydraulic motors for the Metso mobiles screening N05530092 N05530627

Both the A2FM and A6VM are axial piston motors of bent-axis design. The difference is whether the displacement can change.

Rexroth A2FM (fixed displacement)

The A2FM is the workhorse. It covers sizes from 5 to 1000, with a nominal pressure of up to 400 bar and a maximum of 450 bar, in open and closed circuits. Because displacement is fixed, the math is simple: speed follows flow, torque follows pressure.

Take a real example from a distributor spec sheet: an A2FM 63 is a 63 cm³/rev unit with a nominal speed of 5,000 rpm and a 400 bar nominal pressure rating. Those are catalog ceilings, not what you would run a screen at, but they show the headroom.

Best fit on a screen: screen box drives, feeder drives, and conveyor drives where the duty is predictable, and you want a robust, simple part.

Rexroth A6VM (variable displacement)

The A6VM adds a control that can change the swivel angle, and therefore displacement, while running. Rexroth lists it as approved for very high rotational speeds, able to swivel to zero, with high torque, a variety of controls, and both open and closed circuit use. On pressure ratings, sizes 28 to 200 are rated at 400 bar nominal and 450 bar maximum, while sizes 250 to 1000 are rated at 350 bar nominal and 400 bar maximum.

Control options include hydraulic proportional (HD), electric proportional (EP), two-point (HZ, EZ), and automatic controls such as the high-pressure-related HA and speed-related DA. These are all listed in the Series 63 data sheet's contents.

Best fit on a screen: track drives and any function that benefits from trading speed for torque automatically.

Compatibility Checks Before You Order

A motor that fits the flange is not necessarily a motor that fits the machine. Check these in order.

1. Identify the original from the nameplate

Record the full type code, serial number, and material number. Rexroth type codes are specific. They cover series, size, rotation, seal material, shaft type, flange and port style, and any valve or sensor options.

2. Confirm the mechanical interface

Mounting flange, shaft type (splined or keyed), port position, and port standard (SAE or metric). Getting one of these wrong turns a simple swap into a machining job.

3. Match the control and circuit

For A6VM units, the control code matters as much as the size. A motor with the wrong control can run but not behave correctly, and the fault will look like a pump or engine problem.

4. Check case drain and fluid compatibility

Case pressure limits are strict on this motor family. Distributor data for an A2FM 63 notes that housing pressure must stay below 10 bar absolute. Check drain line size and routing. Confirm seal material against your fluid too. Standard mineral oil is the norm, but other fluids need specific approval.

5. Verify with Metso or an authorized supplier

Model, build year, and even engine tier can change what is fitted. Confirm against the Metso parts book, and check the current Rexroth data sheet for your series.

Q1: Are Rexroth A2FM and A6VM motors used on Metso mobile screens?

A1: Bent-axis motors from Rexroth are common across mobile crushing and screening equipment, but the fitted part varies by Metso model, build year, and supplier. Always confirm against the nameplate and the Metso parts documentation rather than assuming.

Q2: How do I know which size I need?

A2: Start from the original type code. If it isn't legible, work back from circuit flow, target speed, and working pressure using the formulas above, then verify against the Rexroth data sheet.

Q3:What is the price and delivery time of the Rexroth A2FM/A6VM motor for the Metso mobile screening?

A3: The specific price and delivery time will depend on the equipment model or specific product model you provide.
