Airtac MD Multi-Position Clamping Cylinder MD25X45
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD25X45 is a genuine MD multi-mount cylinder (double acting), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 245.4 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MD Multi-Position Clamping Cylinder MD25X45
The MD25X45 is a 25 mm bore, 45 mm stroke multi-mount cylinder from AirTAC's MD series. The compact square body fixes from 6 directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space, with magnetic-switch slots machined around the body and high guide precision without added lubrication. Double acting air drives the rod both ways: about 245.4 N of push force and 206.2 N of pull force at 0.5 MPa on this 25 mm bore. Each stroke end is cushioned by a bumper, not an air cushion.
This is a genuine AirTAC part. The MD series is the standard multi-mount design where rod rotation is allowed; choose the MK series if your job needs a no-rotating plate to hold the rod square. As the SKU shows, this model carries no magnet - add the trailing S if you want built-in magnet sensing. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Overall dimensions and fixing patterns vary with stroke, so confirm sizing from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Start with bore: 25 mm double acting gives 245.4 N push at 0.5 MPa, so step up to 32 mm (402.1 N) or down to 20 mm (157.1 N) to match your load. Then pick the family - MD lets the rod rotate, MK prevents rotation. Acting type: double acting (MD/MDD/MDJ), single push (MSD), single pull (MTD), double rod (MDD) or adjustable-stroke (MDJ, adding a 10/20/30 mm adjustable range). This 45 mm stroke sits well inside the 60 mm table limit for a 25 mm bore; note the short cover design cautions against over-long strokes. Choose magnet with a trailing S, and PT thread (default) or G with a trailing G. For side-load ratings and exact dimensions, check the datasheet or ask us.
Applications
Small-parts clamp on assembly fixtures
Clamps a bracket or cover in place before screws are driven. Several MD25X45 units fix side by side on a multi-station base plate, each fed through the same M5 port manifold.
Conveyor gate stopper
The rod extends to swing a stopper blade into the flow, pausing small cartons or parts at a workstation; retraction clears the lane, with the bumper softening each stop.
Jig positioning in weld cells
Pushes workpieces flush against locating pins before welding. The 6-direction fixing lets the cylinder bolt in from whichever face of the jig is free.
FAQ
How much force does the 25 mm bore of the MD25X45 deliver?
At 0.5 MPa this 25 mm double acting cylinder gives about 245.4 N of push force and 206.2 N of pull force (theoretical). The push side is always higher than the pull side. Operating pressure is 0.15-1.0 MPa (22-145 psi); for loads near the limit, confirm sizing with us from the datasheet.
From which directions can I mount this cylinder?
The multi-mount square body fixes from 6 directions: front, back, left, right, top and bottom. That is what lets you mount several units side by side to save space, with switch slots around the body. Exact hole patterns and dimensions for your stroke come from the datasheet, and side-load limits are not published as a figure - ask us.
