Technical Details for the RM004 Series


Globe's RM004 is the smallest in its series, shares the characteristic features of the other compact piston air motors, featuring both low speed and high torque without the need for a gearbox. These motors exhibit exceptional efficiency, delivering high performance and boasting up to 90% more efficiency than other air motors. In contrast to the other compact piston models, the GLOBE RM004 showcases a hard-anodized aluminum housing with plastic wheels on its seven pistons. With a double bearing on the output shaft, it is ideal for direct drive applications, ensuring a lightweight design without compromising power and efficiency.

The motors offer several advantages, including simple and inexpensive variable speed and torque control, indefinite stalling under load, and instant reversibility with a control valve. Additionally, they are resistant to harsh conditions, cool-running due to expanding air, compact and lightweight compared to electric motors, and operate without shock start-up.

Applications for Globe's compact piston air motors include mixing equipment, winding equipment, conveyor belts, hose reels, turntables, packing machines, and cap screwing machines. The oil-free and silicone-free motors are suitable for mixing applications, and special versions are available for the food and chemical industry.
