The AirTAC Airtac MTK Multi-position Locking Cylinder MTK6X20 is a genuine MK multi-mount cylinder (single acting, pull type), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 2.2 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.
The MTK6X20 is a compact MK-series multi-mount cylinder from AirTAC with a square body that can be fixed from 6 directions - front, back, left, right, top and bottom - and mounted side by side to save panel space. This 6mm bore, 20mm stroke version is single acting of the pull type: compressed air retracts the rod, and a bumper provides the cushioning at the end of travel. It operates on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi) and from -20 to 70 C (0 to 150 C only with the optional high-temperature seal material).
This is a genuine AirTAC part in the MK family, meaning a no-rotating plate, brass bushing and fixed rod stop the piston rod from turning - unlike the standard MD series. As the SKU shows, this unit carries no magnet; choose an S-suffix code if you need switch detection. Confirm exact dimensions, pull-side force figures and sizing from the datasheet - we can provide it 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.
At 6mm bore this is the smallest MK size, suited to light holding and return tasks; the pull-type single acting design retracts the rod under air pressure and extends by return, so confirm the pull-side force for this bore from the datasheet before sizing. Operating pressure is 0.2-1.0 MPa (28-145 psi) for all single-acting bores.
Choose MK over MD when the rod must not rotate; MD allows rotation. At 20mm, this stroke sits at the top of the single-acting range (up to 20mm) - keep strokes within the bore's table and avoid asking more of this short-cover body. This cylinder has no magnet (add S for magnet) and PT thread with G available; route side-load questions to us.
Air pulls the stop blade fully clear of a small-parts conveyor lane so product passes unobstructed; the no-rotating rod keeps the blade square.
Mounted under the fixture plate, the cylinder retracts a light locating pin for part removal and re-presentation, with side-by-side mounting beside its neighbors.
The rod pulls an alignment post down out of the way for loading a rectangular workpiece, and the fixed rod prevents the post from twisting.
Yes - single-acting strokes in the MD/MK multi-mount series run up to 20mm, so this 6mm bore, 20mm stroke model is at the top of that range. If you need more travel on a single-acting unit, there is no longer single-acting stroke available in this series; consider the double-acting MD/MK versions or an adjustable-stroke MDJ/MKJ instead, and confirm suitability from the datasheet.
The MK family adds a no-rotating plate, brass bushing and fixed rod to the compact square body, which stops the piston rod from turning - the standard MD series does allow rotation. For mounting, the body can be fixed from 6 directions (front, back, left, right, top and bottom) and units sit side by side to save space. Exact dimensions and side-load capability are per the datasheet, which we confirm on request.
