Airtac MTK Multi-position Locking Cylinder MTK20X10S
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK20X10S is a genuine MK multi-mount cylinder (single acting, pull type), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 92.3 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 MTK20X10S
The AirTAC MTK series is a compact square-body multi-mount cylinder that fixes from six directions (front, back, left, right, top and bottom) and mounts side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. This 20mm bore, 10mm stroke version is single acting of the pull type: air pressure draws the rod in and an internal spring returns it, giving an extended at-rest position for short-retract clamps, stoppers and locating pins. 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 adds a no-rotating plate, brass bushing and fixed rod that stop the piston rod turning, unlike the standard MD family. The trailing S in MTK20X10S 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 model 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
The 20mm bore delivers more pull force than the 16mm in the same compact square body; confirm this model's theoretical single-acting pull figure from the datasheet. Choose MTK when the rod must not rotate, or the standard MD family when rotation is acceptable. This unit is single-acting pull (spring out, air in), not push-type MSK or double-acting MK. The 10mm stroke sits within the 20mm maximum for single-acting bores, and the short covers mean you should not specify more travel than the job needs. The trailing S adds the magnet, and the thread is PT as standard with G offered as an option.
Applications
Stopper gate with sensing
The spring-extended rod raises a stopper paddle to pause parts on a light conveyor, and the magnet lets a switch confirm the gate is down before the next cycle starts.
Pick-and-place eject
Air retracts the rod to pull a small part off a mandrel or nest during pick-and-place transfer, the no-rotating plate keeping the gripper pin aligned throughout.
Indexing station clamp
Cylinders mounted side by side clamp each station of an indexing dial, fixed from whatever body face the tight fixture plate allows, with the magnet confirming clamp state.
FAQ
What does the S in MTK20X10S mean when I select this cylinder?
The trailing S means the cylinder is supplied with a magnet, so magnetic switches seated in the slots around the body can signal rod position. The same cylinder without the magnet is ordered as MTK20X10. The S also does not change the acting type - this remains a single-acting pull cylinder.
Can I mount it side by side, and what limits the stroke?
Yes - the square body is designed to be fixed from any of six directions and to sit side by side with adjacent cylinders, saving space on dense machines. Keep the specified stroke short, as the compact covers suit short travel and an over-long stroke should be avoided. Per-stroke dimensions and allowable side load come from the datasheet; ask us and we will confirm them.
