Radial Piston Air Motors

The Globe RM air motors are a series of compact heavy duty radial piston air motors offering an exceptional range of control valve and output options.  MacScott Bond Ltd holds a large quantity of these motors in stock in order to supply with short lead times.

The RM motors have a four or five cylinder radial piston design, giving positive displacement, with oil bath lubrication and are designed to develop greater power than other motors of equivalent size from 1.7 KW to 23 kW, while being able to start under loaded conditions.

We have all the modular motor, brake and control valve options, foot brackets, filters, regulators, lubricators and silencers available on the shelf .

The motor speed controls are relatively inexpensive and the equipment is rated to ATEX directive 94/9/EC, Annex VIII: Equipment Group II - Category 2 - G D c -T5. 


A variety of operating conditions can be achieved by utilisation of pressure regulators and flow control valves.

RM motors are most suitable for heavy duty applications and can be supplied direct coupled to gearboxes.  For complete range of gearbox options, contact our sales department.
