Airtac MTK Multi-position Locking Cylinder MTK16X5S
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK16X5S is a genuine MK multi-mount cylinder (single acting, pull type), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 60.5 N of pull 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 MTK Multi-position Locking Cylinder MTK16X5S
The AirTAC MTK series is a compact square-body multi-mount cylinder that can be fixed from six directions (front, back, left, right, top and bottom) and mounted side by side to save space. Magnetic-switch slots run around the body and the guide precision is high without added lubrication. This 16mm bore, 5mm stroke version is single acting of the pull type: air pressure draws the rod in and an internal spring returns it, so the at-rest position is extended - useful for short-retract clamps and stoppers that must fail outward. Cushioning is a bumper, the medium is air filtered to 40 um, and the operating pressure range is 0.2-1.0 MPa (28-145 psi).
This is a genuine AirTAC part. The MTK family differs from the standard MD family by a no-rotating plate, brass bushing and fixed rod that stop the piston rod turning, keeping paddles and plates square. The trailing S in MTK16X5S means this cylinder includes a magnet for position sensing. Typical materials are an aluminium-alloy body, covers and piston, a stainless or S45C rod, NBR seals and a TPU bumper; we confirm exact dimensions and theoretical pull force for this bore 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 16mm bore when you need light-duty pull force in a tight footprint; confirm this model's theoretical single-acting pull figure from the datasheet. MTK prevents rod rotation via its no-rotating plate, while the standard MD family allows it. This unit is single-acting pull (spring out, air in) rather than push-type MSK or double-acting MK. The 5mm stroke sits well inside the 20mm maximum for single-acting bores, and the short covers keep the body compact, so keep the specified stroke close to your real travel need. The trailing S adds the magnet, and the port thread is PT as standard, with G offered as an option.
Applications
Small-parts clamp
Air retracts the 5mm rod to release, and the spring returns it to grip small components in a compact fixture that only has room for a square-bodied cylinder bolted on one face.
Gate stopper
The no-rotating rod keeps a stopper paddle square as it rises to block small parts at a workstation, and the spring-extended rest position fails safe if air is lost.
Jig positioning pin
Side-by-side mounting lets several cylinders place locating pins in a jig, each fixed from the most convenient of the six body faces to suit tight tooling layouts.
FAQ
What does the pull-type, single-acting action of the MTK16X5S mean?
Single-acting pull means air pressure draws the rod in and an internal spring returns it, so the rest position is extended. This is different from push-type MSK cylinders (spring in, air out) and from double-acting MK cylinders, and the rated speed for this acting type is 50-500 mm/s.
Where can I mount it, and does the rod stay straight?
The square body fixes from six directions (front, back, left, right, top and bottom), so you can bolt it from whichever face your machine allows. A no-rotating plate, brass bushing and fixed rod stop the rod from turning. Overall dimensions and allowable side load depend on the stroke and come from the datasheet - ask us and we will confirm them.
