Bucher QXM-Mobil Internal Gear Hydraulic Motor

Description

Bucher QXM-Mobil Internal Gear Hydraulic Motor

Bucher developed the QXM-Mobil motor for mobile machinery. The integrated front bearing supports shaft-seal protection and compact installation. Manufacturer information describes low noise and stable torque characteristics across startup and high-speed operation; model selection still depends on the machine and circuit.

This INTEREQ listing covers the Bucher Hydraulics QXM-Mobil product family for identification, replacement enquiries and quotation support. Its product image is an original family illustration and does not depict a confirmed part number or selected configuration. Options and limits vary within a series; confirm the complete manufacturer code before ordering.

Technical specifications

Applications

Mobile-machine fan and blower drives, generator drives, cooling systems, rear-axle support steering and controllable hydraulic power packs where the specified displacement and drive match. Final suitability depends on the machine, hydraulic circuit, duty cycle and installed component configuration. Check the equipment documentation and the manufacturer’s current data before specifying a replacement.

Key features and compatibility

Available model variants include clockwise and counterclockwise rotation, with bidirectional specials on request. Some builds can integrate suction, pressure-relief or flow-control valves, speed sensors and leakage monitoring. Confirm shaft, rotation, flange, port layout, sensor or valve options, and full type code before replacing an installed motor. Interfaces are model-specific. Do not assume that units sharing a series name have matching shafts, flanges, ports, rotation, controls or seals. Published family ranges are identification guides and must not be treated as ratings for every size or combination.

Model identification and replacement selection

Do not select a replacement by brand and series alone. Compare the full nameplate code and confirm displacement, rotation, shaft, mounting flange, port arrangement, controls, case-drain requirements and hydraulic circuit against the installed unit and machine documentation. Send INTEREQ a clear nameplate photo and machine make/model for identification.

For a quotation, provide the full type code, machine model, operating conditions and any available drawing or nameplate image. Condition, availability and technical fit are confirmed for the specific unit offered.

System sizing and replacement check

For system sizing, compare pump displacement and shaft speed with the required flow, then check continuous and intermittent pressure against the machine duty cycle. Confirm inlet conditions, fluid viscosity and cleanliness, operating temperature, case pressure where applicable, drive power and external shaft loads. These conditions affect performance and service life; a series maximum is not an operating target for every unit.

When the installed type code is incomplete, include clear photos of the nameplate, mounting face, shaft and port layout. Provide the machine make/model, current circuit details and operating conditions so the replacement can be checked against the correct manufacturer data sheet.
