Airtac MSK Multi-position Locking Cylinder MSK25X15
The AirTAC Airtac MSK Multi-position Locking Cylinder MSK25X15 is a genuine MK multi-mount cylinder (single acting, push type), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 179.1 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 MSK Multi-position Locking Cylinder MSK25X15
The AirTAC MSK25X15 is a compact multi-mount cylinder that fixes from six directions (front, back, left, right, top and bottom) and mounts side by side with identical cylinders, packing more actuation into less panel space. This single-acting push version extends the rod with air and returns by spring, with a 25 mm bore producing a theoretical 179.1 N of push force at 0.5 MPa across a 15 mm stroke. Cushioning is a bumper, and magnetic-switch slots are provided around the body.
This is a genuine AirTAC part from the MK family, which uses a no-rotating plate, brass bushing and fixed rod to stop the piston rod turning - the standard MD family, by contrast, permits rod rotation. As the SKU shows, this model is without a magnet. We confirm overall dimensions and sizing details 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 the bore by thrust: at 25 mm this single-acting push cylinder gives 179.1 N theoretical push at 0.5 MPa, and the 15 mm stroke sits within the single-acting table that runs up to 20 mm - the short cover means longer strokes are not offered. MK means the rod cannot rotate; choose the standard MD family where rotation is acceptable. This SKU has no magnet and PT thread; add the trailing S for a magnet or G for G thread as your build needs. For side-load figures and exact dimensions, send us your application and we will confirm from the datasheet.
Applications
Small-parts clamp on fixtures
A 15 mm push stroke with 179.1 N at 0.5 MPa holds small components during a machining or assembly step, and 6-direction fixing lets the clamp attach wherever the fixture has room.
Jig indexing and locating
The no-rotating rod keeps a locating pin or indexing pin perfectly oriented as it seats into the jig, while side-by-side mounting places several positioning cylinders on one compact bracket.
Short-stroke eject and press-fit assist
Spring-return push action over 15 mm suits ejecting finished pieces from nests or assisting light press-fit operations where the compact square body must fit between other machine elements.
FAQ
Why choose the 15 mm stroke MSK25X15 over a longer stroke cylinder?
Single-acting push cylinders like the MSK25X15 are offered only in short strokes (up to 20 mm) because of the short cover that houses the return spring, so 15 mm is already near the top of the range. If your job needs a longer stroke, move to the double-acting MD or MK family, where strokes run longer by bore size. Within its range, this 25 mm bore gives 179.1 N theoretical push at 0.5 MPa with a non-rotating rod.
How does the 6-direction mounting work in practice?
The square body has tapped fixing faces on all six sides - front, back, left, right, top and bottom - so the cylinder can be bolted from whichever face suits the machine, and several units sit side by side with a shared pitch to save space. Exact body dimensions vary with stroke, so we route those to the datasheet, along with any side-load question for your fixture.
