Airtac MTK Multi-position Locking Cylinder MTK25X15S
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK25X15S is a genuine MK multi-mount cylinder (single acting, pull type), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 144.4 N of pull 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 MTK Multi-position Locking Cylinder MTK25X15S
The AirTAC MTK25X15S is a compact square-body multi-mount cylinder from the MK family. Its body can be fixed from six directions - front, back, left, right, top and bottom - and units mount side by side to save space, with magnetic-switch slots around the body. This version is single acting of the pull type: air performs the pull stroke and the internal spring returns the rod, which suits a spring-extended pin or stopper that must be retracted by air. The 25 mm bore runs on 0.2-1.0 MPa (28-145 psi) filtered air, travels at 50-500 mm/s and is cushioned by a bumper. Because this is a pull-type cylinder, its thrust is developed on the pull side, which is lower than the push side - confirm the exact pull-side figure from the datasheet.
This is a genuine AirTAC part. The MK family is the no-rotating version of the multi-mount range: a plate, brass bushing and fixed rod stop the rod from turning, so an attached fixture or blade stays square to the body. The trailing S in MTK25X15S means this SKU carries a magnet, and the PT thread is the standard port option for this 25 mm bore. We confirm overall dimensions, rod detail 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
Pick MK over MD when rod rotation must be prevented; the no-rotating plate and fixed rod hold orientation, while MD versions allow the rod to turn. This is a single-acting pull-type unit: air draws the rod in and the spring sends it back out. If you need force in both directions choose a double-acting MK, or an MSK push type where air should extend the rod. The 15 mm stroke sits comfortably inside the single-acting range of up to 20 mm - keep strokes short, as the compact covers are not intended for over-long travel. The trailing S adds a magnet for switch sensing, and the ports are PT thread; a G-thread version is available if your fittings need it. Route any side-load question to us, since allowable values come from the datasheet.
Applications
Conveyor gate stopper
Mounted under the line, the pull-type action retracts a stopper pin with air to release a passing part, then the spring lifts it back up to block the next one. The six-way body fixes neatly in the tight space beneath the rail.
Jig release pin
In an assembly jig, the no-rotating rod keeps a flat locating pin facing the right way while air pulls it out of the workpiece and the spring re-seats it for the next cycle. Units mount side by side where the fixture plate is crowded.
Vertical lift-and-lower positioner
The spring extends the rod to raise a small workpiece or sensor flag, and the air-powered pull stroke lowers it again. The compact square body bolts from the top or bottom of a frame where a full-size cylinder will not fit.
FAQ
What does the S at the end of MTK25X15S mean?
The trailing S means this SKU is built with a magnet, so magnetic switches can sense rod position in the slots around the body; a code without S has no magnet. This model has PT thread as its port option, while a trailing G would indicate G thread.
How can this cylinder be fixed in my machine?
The square body is drilled so it can be fixed from six directions - front, back, left, right, top and bottom - and several units can sit side by side to save space. Overall dimensions and allowable side-load depend on the stroke and bore, so confirm them from the datasheet before designing the mount.
