Airtac MTK Multi-position Locking Cylinder MTK20X15
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK20X15 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 MTK20X15
The MTK20X15 is a genuine AirTAC multi-mount cylinder: a compact square-body cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side with other cylinders to save space on a manifold or fixture plate. This unit is the 20mm bore, 15mm stroke, single acting pull type variant: one air supply does the work, which keeps plumbing simple 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 rather than an air cushion, and operates at 50-500 mm/s. Because the body is short, confirm the pull-side thrust figure for this single acting variant from the datasheet before sizing the job.
This is a genuine AirTAC part from the MK family, which is the no-rotating range: a fixed rod and no-rotating plate with a brass bushing stop the piston rod from turning, so an attached plate or lever stays square. The SKU shows no magnet, so this cylinder is not the magnet-equipped version. Typical materials include an aluminium-alloy body, a stainless or S45C rod and NBR seals. 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 the 20mm bore when you need a compact single acting pull cylinder in the middle of the range; because this is a pull-type variant, route the thrust figure for your pressure to the datasheet rather than sizing from push-side numbers. If you need the rod held against rotation, MK is the right family over MD, which allows rotation. Acting choices in this series are double acting (MK), single acting push (MSK), single acting pull (MTK, this unit), double rod (MKD) and adjustable stroke (MKJ). The 15mm stroke sits within the 20mm maximum for single acting versions; the short covers caution against over-long strokes, and side-load capacity should be confirmed with us. This SKU has no magnet and uses a PT thread; a G thread and the S magnet option are available on other SKUs.
Applications
Conveyor parts stopper
Fix the square body from the side or bottom of a conveyor frame and hang a stopper plate on the non-rotating rod; the MK design keeps the plate facing square to the flow of parts.
Index table lock pin
Mount the cylinder under a rotary indexing table and use the pull-type single acting action to engage and release a locating pin with a single air line, saving valve and tubing count.
Jig positioning pin
Side-by-side mounting on a drill or assembly jig lets several cylinders occupy one rail, with the fixed rod holding each positioning pin at a repeatable angle.
FAQ
What does MTK20X15 mean in the model code?
MTK is the AirTAC multi-mount no-rotating cylinder family in the single acting pull type variant. The first number, 20, is the bore in mm, and the number after X, 15, is the stroke in mm. There is no trailing S, so this SKU is without a magnet, and there is no trailing G, so the thread is PT.
Can I mount this cylinder from any direction?
Yes. The multi-mount square body can be fixed from six directions - front, back, left, right, top and bottom - and cylinders can sit side by side to save space. Because the covers are short, keep the stroke within the single acting 20mm maximum and confirm side-load capacity and exact dimensions from the datasheet.
