The AirTAC Airtac MTK Multi-position Locking Cylinder MTK25X5 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.
The MTK25X5 is a compact square-body multi-mount 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 panel space. This version is single acting, pull type: one air connection retracts the rod and the return happens inside the cylinder, so there is no second supply line to plumb. The 25 mm bore runs at 0.2-1.0 MPa (28-145 psi) with speeds of 50-500 mm/s, and the 5 mm stroke is a very short travel for quick release or retention jobs. The cushion is a bumper that absorbs end-of-stroke impact, and switch slots are machined around the body.
This is a genuine AirTAC part. The MK family is the no-rotating version of the multi-mount range: a fixed rod and plate keep the rod from turning, unlike the standard MD family where the rod is free to rotate. This SKU carries no magnet (no trailing S in the code), so piston position cannot be sensed by a switch in the body slots; choose an S variant if sensing is needed. Exact dimensions and sizing for this stroke are confirmed 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.
Choose the 25 mm bore when its force class suits the job: single-acting pull-side force is lower than the push side, so confirm the exact figure from the datasheet before sizing. MTK is the no-rotating, single-acting pull member of the MK family; if you need rotation instead, step to the MD family. The 5 mm stroke sits well inside the single-acting limit of up to 20 mm, and the short covers caution against over-long strokes in this body style. This SKU has no magnet; add the trailing S (MTK25X5S) for switch sensing. Port thread is PT by default with G available. Allowable side load is not published here; ask us and we will route you to the datasheet.
Mounted beside a light conveyor line, the rod sits out to block small parts and one air line pulls it back to release a batch; the no-rotating plate keeps the blocking face square to the product flow.
On a compact pick-and-place head, the short pull stroke retracts a support pin or tool stop on demand, and the fixed rod stops the attachment from twisting between cycles.
Fixed from the side or bottom of a small assembly jig, several of these cylinders mount flush next to each other to index or retain parts in tight fixture plates.
M marks the AirTAC multi-mount family, K means the no-rotating version, and T means single acting, pull type. One air line retracts the rod and the return is automatic, so only one connection is needed. Unlike the standard MD family, the MK design prevents the rod from turning.
Side-load capacity is not a figure we publish here, and overall dimensions vary with stroke, so confirm both from the datasheet or ask us directly. What we can confirm is the six-direction fixing, the side-by-side mounting that saves space, and the magnetic-switch slots around the body.
