Airtac MSK Multi-position Locking Cylinder MSK16X5
The AirTAC Airtac MSK Multi-position Locking Cylinder MSK16X5 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 MSK16X5
The MSK16X5 is an AirTAC MK-series multi-mount cylinder: a compact square-body unit that fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side with matching cylinders to save space. This version is single acting, push type, with a 16 mm bore and a short 5 mm stroke, so air pushes the rod out and a spring pulls it back. At 0.5 MPa the theoretical push force is about 70.4 N - useful for short-travel ejection, marking or part presence tasks - and the cushion is a bumper. No added lubricant is needed.
This is a genuine AirTAC part. The MK family is the no-rotating variant: a fixed rod and no-rotating plate typically stop the piston rod from turning, keeping a short push exactly where it is aimed. The SKU shows no magnet, so this cylinder is supplied without magnetic position sensing. We can confirm dimensions, weights 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 for thrust: at 0.5 MPa the 16 mm single-acting push gives about 70.4 N, so move to a bigger bore if the job needs more force. MK prevents rod rotation while MD allows it, so MK suits pads and pins that must stay square. MSK is single-acting push (spring return); MK double acting and MTK single-acting pull are the other options.
The 5 mm stroke is a very short travel - ideal for a quick push or indicator, but check it covers your part variation before ordering, since the single-acting stroke table runs up to 20 mm. The SKU has no trailing S, so no magnet is fitted; add S if you need switch feedback. Port thread is PT by default with a G option, M5x0.8 on this bore. Side-load capacity is a datasheet question - route it to us.
Applications
Part presence ejection
A short 5 mm push nudges off-spec parts off a conveyor or out of a nest, and the non-rotating rod keeps the ejector pin aimed exactly; spring return resets instantly.
Jig locating pin
Fixed from the bottom of a fixture, the square-body cylinder advances a locator pin a precise 5 mm into a datum hole, with the plate staying square to the jig.
Small-parts clamping
The single-acting push holds a light part against a stop during a marking or testing step; losing air releases the clamp automatically via spring return.
FAQ
When is the 5 mm stroke on this single-acting cylinder the right choice?
Use it where the travel needed is only a few millimetres - ejecting a part, seating a locating pin or holding a small clamp - because the push comes from the 16 mm bore at about 70.4 N at 0.5 MPa while the stroke stays minimal. If your application needs more travel, the single-acting stroke table goes up to 20 mm; for longer strokes move to the double-acting MK or MD family.
How does the no-rotating feature help in tight multi-cylinder layouts?
Because the MK design adds a fixed rod and no-rotating plate, the rod cannot turn as it extends, so pins, pads and stopper blades stay square to the load without an external guide. Combined with the 6-direction fixing and side-by-side mounting of the square body, several MSK16X5 units can be packed closely together on a jig or line and each still push precisely where aimed.
