Multiquip EM400539 Air Cylinder

The Multiquip EM400539 Air Cylinder is a genuine OEM replacement designed for the FM9 finishing machine. Sourced directly from Multiquip, this part is manufactured to the same specifications as the original component installed at the factory, ensuring a direct, trouble-free installation. Verified fitment for FM9 series equipment makes this the correct choice when replacing a worn or failed air cylinder on your machine.

Key Features

• Genuine OEM Construction — Manufactured to original Multiquip specifications, delivering the correct bore diameter, stroke length, and pressure tolerances required for consistent pneumatic actuation on the FM9.
• Direct-Fit Replacement — Matches the original mounting points and port connections of the FM9 finishing machine, allowing straightforward installation without modification to existing hardware.
• Confirmed FM9 Fitment — Verified for use on the Multiquip FM9 finishing machine, so you can order with confidence that this is the right part for your equipment.
• Restored Actuation Performance — A functioning air cylinder delivers precise, repeatable mechanical movement; a worn or seized cylinder leads to inconsistent operation and can bring finishing work to a halt.
• Pressure-Rated Seals and Housing — Built with materials rated to handle the pneumatic pressures present in the FM9 system, supporting sustained duty cycles in demanding finishing applications.

An air cylinder converts compressed air pressure into controlled linear mechanical force, driving the movement of components within the finishing machine. When the air cylinder is operating correctly, it provides smooth, consistent actuation that keeps the machine performing as intended. A worn, cracked, or leaking cylinder causes loss of pressure, erratic movement, or complete failure of the driven mechanism — making timely replacement essential to keeping finishing operations on schedule.
