Airtac MTK Multi-position Locking Cylinder MTK25X15
The AirTAC MTK Multi-position Locking Cylinder MTK25X15 is a genuine MK multi-mount cylinder (single acting, pull type), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 144.4 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 MTK25X15
The MTK25X15 is a 25 mm bore, 15 mm stroke single-acting, pull type multi-mount cylinder from AirTAC's MK series. Its compact square body can be fixed from 6 directions - front, back, left, right, top and bottom - and cylinders can be mounted side by side to save space, with magnetic-switch slots around the body and high guide precision with no added lubricant. Single-acting, pull type operation means air works on one side only, running on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), with a bumper as the cushion and speeds of 50-500 mm/s.
This is a genuine AirTAC part. The MK family is the no-rotating version of the standard MD series: a no-rotating plate, brass bushing and fixed rod stop the piston rod from turning. This SKU (MTK25X15) is supplied without a magnet; add the S suffix (MTK25X15S) if you need one. Because this is a single-acting, pull type model, its pull-side force is lower than the push-side figure - we confirm the exact value, plus 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
The 25 mm bore is the strongest option in the MK single-acting range; as a pull type, its pull-side force is lower than the push side, so confirm the exact figure from the datasheet before sizing. If the rod must push rather than pull, the MSK is the single-acting push type and the MK is the double-acting option. The 15 mm stroke sits within the single-acting table limit of 20 mm, though the short single-acting covers caution against an over-long stroke. This SKU is without a magnet; add the S suffix for switch detection. Port thread is PT as standard, with G available.
Applications
Pull-clear indexing pins
Use the 15 mm pull stroke to withdraw indexing pins between positions on a compact rotary fixture, with the no-rotating rod keeping each pin's keyway oriented.
Sliding guide-gate retract
Fix the body sideways to a machine plate with the 6-way mount and let the pull stroke slide a small guide gate out of the path of parts moving between stations.
Fixture part-ejection assists
Mount MTK25X15 units side by side under a small assembly fixture so the pull stroke clears ejector fingers or retainers once a completed part is lifted out.
FAQ
Is a 15 mm stroke within range for this single-acting cylinder?
Yes. Single-acting MD/MK cylinders cover strokes up to 20 mm, so 15 mm fits, though the short single-acting covers caution against stretching the stroke too long. Confirm the exact body dimensions for your stroke from the datasheet.
What stops the rod from rotating on the MTK25X15?
The MK family adds a no-rotating plate, brass bushing and fixed rod that keep the piston rod from turning, unlike the standard MD series. This matters for pull applications such as pin or latch retraction where the rod's orientation must stay fixed. Side-load limits and dimensions come from the datasheet.
