Airtac MKJ Adjustable Cylinder MKJ16X40-20S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ16X40-20S is a genuine MK multi-mount cylinder (adjustable stroke), 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.

About the Airtac MKJ Adjustable Cylinder MKJ16X40-20S
The MKJ is AirTAC's adjustable-stroke, no-rotating multi-mount cylinder - a compact square body that fixes from six directions (front, back, left, right, top, bottom) and mounts side by side to save space. This bore 16 model is double acting, with a 40 mm stroke plus a 20 mm adjustable range and a bumper cushion. At 0.5 MPa it develops about 100.5 N of theoretical push force, suitable for light clamping, gating and positioning in confined panels.
This is a genuine AirTAC part. The MK family stops the rod from rotating via a fixed rod and no-rotating plate, unlike the standard MD family; the trailing S means the magnet is fitted, with magnetic-switch slots around the body for detection. 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
Bore 16 gives 100.5 N theoretical push (86.4 N pull) at 0.5 MPa - pick another bore if you need a different thrust band. Choose MKJ when the rod must not rotate and you need stroke flexibility: the J suffix adds a 20 mm adjustable range over the 40 mm stroke, within the bore 16 double-acting table (up to 50 mm). Keep strokes short for the compact covers and route side-load questions to us. The S suffix means magnet fitted; ports are M5x0.8, PT thread standard or G on request.
Applications
Small-parts clamp
Clamps small brackets in an assembly fixture, mounted through the body from whichever of the six directions the fixture allows.
Rotary indexer stop
Stops an indexing dial at each station, with the no-rotating rod holding the stopper face square and the adjustable range trimming the stop point.
Lateral part push
Slides components sideways into a magazine or chute, side-by-side mounting letting several units share one compact machine panel.
FAQ
How much force does this bore 16 cylinder give, and when should I change bore?
At 0.5 MPa the bore 16 double-acting unit develops about 100.5 N theoretical push force (86.4 N on the pull side). If your job needs more, step up to a 20, 25 or 32 mm bore; if less, a smaller bore saves space. Theoretical figures only - check application loads against the datasheet.
Can I mount it from any side?
Yes - the square body fixes from six directions: front, back, left, right, top and bottom, and units mount side by side to save space. Exact body and mounting dimensions vary with stroke, so confirm them from the datasheet; side-load limits should also be checked with us before use.
