Airtac MTK Multi-position Locking Cylinder MTK20X20
The AirTAC MTK Multi-position Locking Cylinder MTK20X20 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 MTK20X20
The MTK20X20 is a genuine AirTAC multi-mount cylinder: a compact square-body cylinder fixed from six directions - front, back, left, right, top and bottom - and able to sit side by side with other cylinders to save space on shared mounting rails. This unit is the 20mm bore with a 20mm stroke, the maximum for single acting versions in this range, in the single acting pull type: one air supply does the work, simplifying plumbing on dense fixtures. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), tolerates -20 to 70 C, cushions with a bumper, and operates at 50-500 mm/s. Because it is a pull-type single acting variant, confirm the pull-side thrust figure from the datasheet before sizing.
This is a genuine AirTAC part from the MK family, the no-rotating range: a fixed rod, no-rotating plate and brass bushing prevent the piston rod from turning, so an attached plate or lever keeps its orientation. The SKU shows no magnet, so this is the non-magnet version. Typical materials are an aluminium-alloy body, stainless or S45C rod and NBR seals, with bore-specific detail in the datasheet. 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
Select the 20mm bore for a compact single acting pull cylinder at the top of the series' 20mm single acting stroke range; since thrust depends on the pull side for this variant, confirm the figure at your working pressure from the datasheet rather than borrowing a push-side number. MK is the family to choose when rod rotation must be prevented, while MD suits jobs where rotation is acceptable. Acting choices are double acting (MK), single acting push (MSK), single acting pull (MTK, this unit), double rod (MKD) and adjustable stroke (MKJ). The short covers caution against over-long strokes, and side-load capacity should be confirmed with us. This SKU has no magnet and a PT thread; the S magnet and G thread options sit on other SKUs.
Applications
Eject-and-clear stopper
Fix the body to the underside of a conveyor rail and carry a stopper blade on the non-rotating rod, using the full 20mm single acting stroke to swing the blade clear of passing parts.
Assembly fixture locators
Mount several units side by side on a fixture plate so each locator pin shares one rail, with the MK fixed rod holding every pin at a consistent angle.
Chute diverter gate
Install the cylinder vertically beside a discharge chute and link the rod to a diverter plate; the no-rotating design keeps the plate travel straight with one air line.
FAQ
Why is the 20mm stroke the limit on this cylinder?
Single acting versions of the MD/MK multi-mount range are limited to a 20mm stroke because the covers are short, and an over-long stroke should be avoided. If you need more travel, look at the double acting MK variants, which reach 60mm at this bore, or confirm the options with us from the datasheet.
How do I decode MTK20X20 and what thread does it use?
MTK means the no-rotating multi-mount MK family in the single acting pull type variant. The bore is 20mm and the stroke is 20mm. No trailing S means no magnet, and no trailing G means the port thread is PT. The port size on the 20mm bore is M5x0.8.
