Airtac MSK Multi-position Locking Cylinder MSK25X10S
The AirTAC Airtac MSK Multi-position Locking Cylinder MSK25X10S 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 MSK25X10S
The AirTAC MSK25X10S is a compact multi-mount cylinder that fixes from six directions (front, back, left, right, top and bottom) and mounts side by side with matching units, keeping actuation points dense and compact on the machine frame. This single-acting push version extends with air and returns by spring, with a 25 mm bore giving a theoretical 179.1 N of push force at 0.5 MPa over a short 10 mm stroke. Cushioning is a bumper, and magnetic-switch slots run around the body for position detection.
This is a genuine AirTAC part from the MK family, where a no-rotating plate, brass bushing and fixed rod stop the piston rod from turning - the standard MD family instead allows rod rotation. The trailing S in the SKU means this model is WITH a magnet for switch detection; non-S codes are without. We confirm 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
Select the bore for thrust: this 25 mm single-acting push unit delivers 179.1 N theoretical push at 0.5 MPa, and single-acting strokes top out at 20 mm, so 10 mm fits short clamp or stopper moves. MK prevents rod rotation; if your mechanism tolerates rotation, compare the standard MD family. The trailing S means the magnet is fitted on this SKU - drop the S if you do not need switch detection. PT thread is standard here; order the G variant for G-thread piping. Mind the short cover when specifying stroke, and route side-load and mounting questions to us for datasheet confirmation.
Applications
Fixture clamping with position check
The 179.1 N push at 0.5 MPa clamps small parts reliably, and with the magnet fitted the switch slots let the PLC confirm the clamp has actually reached the part before the cycle continues.
Conveyor stopper with sensing
As a line stopper, the no-rotating rod keeps the blade aligned with the product flow, and the built-in magnet allows both up and down positions to be verified on the fixture rail.
Pick-and-place present detection
In compact pick-and-place heads, the 10 mm push stroke presents or releases small components while side-by-side mounting of multiple cylinders keeps the tooling plate slim and organized.
FAQ
What does the S at the end of MSK25X10S mean?
The trailing S means this cylinder is supplied WITH a magnet in the piston, so reed or Hall-effect switches in the slots around the body can detect rod position. The equivalent code without the S (MSK25X10) is the same cylinder but without a magnet. In either case the MK family is single-acting push: air extends the rod, a spring returns it, and the rod is prevented from rotating.
Where can I mount it, and what loads can the rod take sideways?
The square body fixes from all six directions - front, back, left, right, top and bottom - and cylinders mount side by side, which is the core space-saving advantage of the multi-mount design. Keep in mind the short single-acting cover limits available stroke, and allowable side-load is not a published figure here: send us your mounting arrangement and we will confirm the correct values from the datasheet.
