Airtac MTK Multi-position Locking Cylinder MTK16X20S
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK16X20S 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 MTK16X20S
The MTK16X20S is a compact multi-mount cylinder with a square body that fixes from six directions - front, back, left, right, top and bottom - so units sit side by side to save space, with magnetic-switch slots around the body. This model is a 16 mm bore, 20 mm stroke, single-acting pull-type cylinder from AirTAC's MK family: air retracts the rod, and a no-rotating plate with fixed rod stops the rod turning. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi) at 50-500 mm/s, with a bumper cushion.
This is a genuine AirTAC part. The MK family is the no-rotating counterpart of the standard MD family, adding a no-rotating plate, brass bushing and fixed rod (typical construction; bore-specific detail is on the datasheet). The trailing S in the SKU means a magnet is built in, and the thread is PT. Dimensions vary with stroke, so 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
Choose MTK when air must retract the load rather than extend it: MTK is the single-acting, pull-type member of the no-rotating MK family, while MD stays standard and MSD/MSK push instead. The 16 mm bore operates at 0.2-1.0 MPa (28-145 psi); theoretical thrust for this bore and acting side is on the datasheet - ask us to confirm it. The trailing S gives you a magnet for switch position feedback; without the S the body has no magnet. Single-acting strokes in this bore run up to 20 mm and the covers are short, so avoid over-long strokes and route side-load questions to us. Thread is PT here; G is available.
Applications
Aligned pick-and-place probe
Use the non-turning rod to keep a small gripper or vacuum plate square during vertical pick-and-place moves, while the built-in magnet lets a switch confirm up and down positions in the body slots.
Indexed release stopper
Hold or release parts at a station on an indexing line: the no-rotating plate keeps the contact face square through the 20 mm retract stroke and the magnet feeds position signals to the controller.
Compact diverter row
Line up several magnet-fitted bodies side by side along a conveyor to drive short diverters, using the six-direction fixing to bolt each unit where frame space is tight.
FAQ
What does the S at the end of MTK16X20S mean?
The trailing S means this cylinder is built with a magnet, so magnetic switches seated in the slots around the body can sense rod position. The same cylinder without the S suffix has no magnet. MTK itself decodes as the single-acting, pull-type version of the no-rotating MK family, 16 mm bore, 20 mm stroke, PT thread.
How does the multi-mount body help in a tight build?
The square body fixes from six directions - front, back, left, right, top and bottom - so you can bolt it through whichever face suits the fixture and mount several units side by side to save space. For allowable side-load and exact stroke-dependent dimensions, confirm from the datasheet.
