Airtac MKD Multi-position Clamping Cylinder MKD25X5
The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD25X5 is a genuine MK multi-mount cylinder (double rod), 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. As an MK unit a fixed rod stops the piston rod rotating.

About the Airtac MKD Multi-position Clamping Cylinder MKD25X5
The AirTAC MKD25X5 is a compact square-body multi-mount cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side to save space. With a 25 mm bore, a very short 5 mm stroke and a double-rod, double-acting design, it delivers a theoretical push force of 245.4 N and 206.2 N on the pull side at 0.5 MPa, making it well suited to small, fast nudging or clamping moves from either end. Cushioning is provided by a bumper, and it runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to 70 C.
This is a genuine AirTAC part from the MK family, the no-rotating version of the multi-mount cylinder: a fixed rod and plate stop the piston rod from turning, so attached tooling keeps its orientation. This SKU has no magnet (no trailing S), so switch-based position sensing is not supported as shown. We can confirm exact dimensions and 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
The 25 mm bore gives up to 245.4 N theoretical push (206.2 N pull) at 0.5 MPa, so this cylinder suits short, firm moves rather than long travel. MKD gives you a rod on both ends, unlike the single-rod MK, single-acting MSK/MTK, or adjustable-stroke MKJ. The 5 mm stroke is at the low end of the bore's double-acting table, which runs up to 60 mm for bores 20/25/32; if your stroke might grow, pick a longer variant now rather than stretching this one. No magnet is fitted (add S for sensing) and the thread is PT (specify G for the alternate). Side-load capacity is not quoted here; confirm it from the datasheet.
Applications
Short-throw part clamping
The 5 mm stroke is ideal for a final lock-down clamp on a small part in a machining or assembly jig, pushing hard over a tiny travel with the rod held rotation-free.
Lane-to-lane part nudging
Mount the MKD25X5 beside a conveyor edge to nudge parts a few millimeters into a guide or sensor position, with rods on both ends to serve two lanes.
Micro height correction
Fix the body from 6 directions under a fixture plate to make a precise 5 mm lift or settle of a workpiece, with the no-rotating plate keeping the lift flat.
FAQ
Is a 5 mm stroke enough, or should I choose a longer one?
A 5 mm stroke suits short clamping, nudging or correction moves. The bore's double-acting stroke table goes up to 60 mm for a 25 mm bore, but the covers on these cylinders are short, so an over-long stroke is best avoided. If your requirement could grow, select a longer stroke variant now; we can help size it from the datasheet.
What does the double-rod MKD design give me over a standard MK?
MKD provides a working rod on both ends of the no-rotating body, so you can act on a load from either side or share the push across two tooling points. Like all MK cylinders, the fixed rod and plate prevent rod rotation. At 0.5 MPa this 25 mm bore gives a theoretical 245.4 N push and 206.2 N pull.
