Airtac MSK Multi-position Locking Cylinder MSK16X5S
The AirTAC Airtac MSK Multi-position Locking Cylinder MSK16X5S is a genuine MK multi-mount cylinder (single acting, push type), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 70.4 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 MSK Multi-position Locking Cylinder MSK16X5S
The AirTAC MSK16X5S is a compact multi-mount cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom), so several units can be mounted side by side to save space. The body also carries magnetic-switch slots around it. This no-rotating version has a 16mm bore and a very short 5mm stroke with single-acting push operation: air pressure extends the rod and the built-in bumper cushions it, delivering a theoretical thrust of 70.4 N at 0.5 MPa. The 5mm stroke suits tiny, fast repositioning jobs in tight spaces.
This is a genuine AirTAC part in the MK family, whose no-rotating plate, brass bushing and fixed rod stop the piston rod from turning - unlike the standard MD family, where rotation is allowed. The trailing S in the model code shows this unit comes WITH a magnet; versions without the S do not include one. Typical materials include an aluminium-alloy body, stainless or S45C rod, NBR seals and a TPU bumper. Overall dimensions vary with stroke - we confirm exact 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
Choose the bore by thrust: at 0.5 MPa this 16mm bore gives a theoretical push of 70.4 N; if you need more force, step up to 20mm (110.0 N) or 25mm (179.1 N) in the same single-acting push format. MK differs from MD in that the MK no-rotating design prevents rod rotation, while MD allows it - pick MK when orientation of the workpiece or plate must be held. MSK is single acting push (spring return), MSD/MTD cover other single-acting types, and MD/MDD/MDJ are double acting. Single-acting strokes run up to 20mm, so this 5mm stroke fits the table; note the short cover cautions against specifying an over-long stroke. The trailing S means a magnet is fitted. Thread is PT by default - order the G variant if G threads are needed, with M5x0.8 ports on this bore.
Applications
Small-parts clamping
The short 5mm push stroke and no-rotating rod let a compact MSK16X5S clamp small parts square to the fixture, with several units fixed side by side on one jig plate.
Gate and stopper actuation
On light conveyor lines, the 6-direction fixing lets this cylinder bolt wherever a stopper or gate pivot needs it, and the non-turning rod keeps the stopper plate aligned.
Jig positioning pins
A single-acting push cylinder with a fixed-orientation rod extends a positioning pin into a locating hole each cycle; the bumper cushions the spring-less return seat.
FAQ
What does MSK16X5S mean?
MSK is the AirTAC MK-family single-acting push type with a no-rotating rod. 16 is the bore in mm, 5 is the stroke in mm, and the trailing S means the cylinder comes with a magnet. No trailing G means the standard PT thread. Single-acting push cylinders extend on air pressure and return by spring, running at 50-500 mm/s on 0.2-1.0 MPa (28-145 psi).
How many ways can this cylinder be mounted?
The multi-mount body can be fixed from 6 directions - front, back, left, right, top and bottom - so units can sit side by side to save space, with magnetic-switch slots around the body. Because this is a short-cover single-acting cylinder, keep the stroke within the single-acting range (up to 20mm) and confirm exact dimensions and any side-load limits from the datasheet.
