Airtac MK Series Multi-position Locking Cylinder MK16X5S
The AirTAC Airtac MK Series Multi-position Locking Cylinder MK16X5S is a genuine MK multi-mount cylinder (double acting), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 100.5 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 MK Series Multi-position Locking Cylinder MK16X5S
The AirTAC MK series is a compact multi-mount cylinder with a square body that fixes from six directions - front, back, left, right, top and bottom - so units can sit side by side to save space. This MK16X5S is double acting with a 16 mm bore and a very short 5 mm stroke, delivering a theoretical push force of 100.5 N (86.4 N on the pull side) at 0.5 MPa - suited to tight clamping and locating jobs where only a short move is needed. Cushioning is a bumper, and magnetic-switch slots run around the body, giving high guide precision without added lubricant.
This is a genuine AirTAC part. Unlike the standard MD series, where rod rotation is allowed, the MK family adds a no-rotating plate, brass bushing and fixed rod (typical - see the datasheet for bore-specific detail) that stop the piston rod from turning. The trailing S on this SKU means the magnet is fitted; a code without S would be supplied without one. Operating range at this bore is 0.15-1.0 MPa (22-145 psi). We confirm dimensions 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 the 16 mm bore when the job needs roughly 100.5 N of push (86.4 N pull) at 0.5 MPa; smaller bores save more space, larger bores give more force. Choose MK over MD when the rod must not rotate; MD is the standard series where rotation is allowed. This unit is double acting with a 5 mm stroke, well inside the bore-16 table (up to 50 mm), and the short cover keeps the body compact - avoid specifying more stroke than the task needs. The trailing S orders the magnet; leave it off if switches are not used. Thread is PT as standard, with G available. Route side-load limits to us or the datasheet.
Applications
Small-parts clamp
Clamps small brackets or formed parts at a workstation fixture. The fixed rod keeps the clamp pad square to the part, and the 5 mm stroke is enough for a quick clamp-and-release cycle.
Jig positioning
Locates and positions a jig in an assembly or machining fixture. The square body fixes from six directions, so the cylinder bolts flush against the jig plate without extra brackets.
Conveyor stop pin
Acts as a short-stroke stopper on a small conveyor line. Units mount side by side on one rail, so several stop positions can share a single mounting strip.
FAQ
What does the S at the end of MK16X5S mean?
The trailing S means this cylinder is supplied WITH a magnet in the piston, so magnetic switches can sense rod position via the switch slots around the body. A code without the S, such as MK16X5, is the same cylinder without the magnet. The thread is PT as standard; add G to the code to order the G-thread version.
How is this cylinder mounted and what are its limits?
The square multi-mount body fixes from six directions - front, back, left, right, top and bottom - and units can be mounted side by side to save space. Allowable side-load figures and the per-stroke overall dimensions are not listed here; confirm them from the datasheet or ask us before designing the fixture.
