The AirTAC Airtac MK Series Multi-position Locking Cylinder MK16X25S is a genuine MK multi-mount cylinder (double acting), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 100.5 N of push force at 0.5 MPa. A bumper cushions the impact. As an MK unit a fixed rod stops the piston rod rotating.
The MK16X25S is an AirTAC MK series multi-mount cylinder with a 16 mm bore and 25 mm stroke. Its square body fixes from 6 directions (front, back, left, right, top and bottom), letting you mount units side by side to save space, and magnetic-switch slots run around the body. As a double acting MK cylinder it gives about 100.5 N of theoretical push force at 0.5 MPa on this bore, with a bumper cushioning the stroke at each end.
This is a genuine AirTAC part. The MK family is the no-rotating version: a fixed rod and plate stop the rod from turning, unlike the standard MD series. The trailing S means this SKU is supplied WITH a magnet for position sensing; it is an option, not a standard fitting on every model. Ports are PT thread (M5x0.8 on this bore). Confirm dimensions and switch layout 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.
The 16 mm bore provides roughly 100.5 N theoretical push at 0.5 MPa (about 86.4 N on the pull side); move to 20, 25 or 32 mm bore if you need more thrust. MK prevents rod rotation; MD is the standard type if rotation is tolerable. This is a double acting cylinder and the 25 mm stroke is within the bore 16 range (up to 50 mm) - avoid over-long strokes, as the short covers limit them. The S suffix adds the magnet, useful when you want position feedback in the body slots; choose MK16X25 without the S if you do not. Thread is PT, with G available. Route side-load questions to us or the datasheet.
The magnet signals end positions in the body slots while the non-rotating rod keeps a gripper aligned on small parts in pick-and-place stations.
Fixes from 6 directions on a machining fixture, clamping workpieces with about 100.5 N push force at 0.5 MPa on the 16 mm bore.
Mounted side by side in an indexing bank, each unit advances and retracts parts between stations with the bumper cushioning both ends.
The trailing S means this SKU is supplied WITH a magnet, so magnetic proximity switches can be detected in the slots around the square body. The same cylinder without the S (MK16X25) has no magnet. Magnet is an optional fitting on MD/MK cylinders, not a standard feature on every model.
The bore 16 multi-mount body uses short covers and is designed for compact duty; its stroke table tops out at 50 mm, and over-long strokes are not suited to the format. Keep within the published table, mount from any of the 6 directions, and confirm dimensions and side-load from the datasheet.
