The AirTAC Airtac MK Series Multi-position Locking Cylinder MK16X45S 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 MK16X45S is an AirTAC MK-series multi-mount cylinder, a compact square-body pneumatic cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side to save space. With a 16 mm bore and 45 mm stroke in a double acting configuration, air drives the rod out and retracts it. At 0.5 MPa the bore delivers a theoretical push force of 100.5 N for light clamping, gating and positioning work. Cushioning is by a bumper.
This is a genuine AirTAC part. The MK family adds a no-rotating plate, bushing and fixed rod so the piston rod is prevented from turning, unlike the standard MD family; choose MK when a fixture or plate must stay square. The trailing S in the code means this SKU includes a magnet for switch position sensing. We confirm dimensions and sizing details 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.
Bore sets the force: a 16 mm bore gives about 100.5 N theoretical push (86.4 N pull) at 0.5 MPa. Choose MK when rod rotation must be prevented, MD when it is allowed. Acting type: MK is double acting here; single push (MSK), single pull (MTK), double rod (MKD) and adjustable-stroke (MKJ) exist. Stroke 45 mm is within the bore 16 table limit of 50 mm; the short cover means avoid stretching to over-long strokes. The S in this code specifies the magnet; drop the S if you do not need switch sensing. Thread is PT by default or G with a trailing G.
Mount the body under a small gantry and use the magnet plus a switch to confirm the rod is fully down before the vacuum cup releases the part. The no-rotating rod keeps the end tool oriented.
Fix the body from the top of the frame and extend the rod to hold parts at a workstation. Side-by-side mounting lets several stoppers share one compact manifold of space.
Locate and position small brackets in a jig with about 100.5 N push at 0.5 MPa. The square body fixes from any of 6 directions, so it fits crowded fixture plates.
The trailing S means this cylinder is built with a magnet in the piston, so magnetic switches can sense rod position on the body's switch slots. The same cylinder without the S (MK16X45) has no magnet. Magnet is an option, not a default, on this series.
No. Like all MK multi-mount cylinders, the square body fixes from 6 directions: front, back, left, right, top and bottom, and units mount side by side. The no-rotating plate, bushing and fixed rod simply stop the rod from turning, which helps where an attached plate must stay square. Side-load limits and dimensions per stroke come from the datasheet.
