Airtac MKJ Adjustable Cylinder MKJ16X30-20
The AirTAC Airtac MKJ Adjustable Cylinder MKJ16X30-20 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 MKJ16X30-20
The MKJ16X30-20 is an AirTAC adjustable-stroke, no-rotating multi-mount cylinder with a compact square body that can be fixed from 6 directions: front, back, left, right, top and bottom. Units mount side by side to save space in dense machine panels, and magnetic-switch slots run around the body. This version has a 16 mm bore, 30 mm base stroke plus a 20 mm adjustable range, and double-acting air power; at 0.5 MPa it produces a theoretical push thrust of 100.5 N, cushioned by a bumper. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and -20 to 70 C, with no added lubricant needed.
This is a genuine AirTAC part. The MK family uses a no-rotating plate, brass bushing and fixed rod to keep the piston rod from turning, while the standard MD family allows rod rotation. The model code has no trailing S, so this SKU is supplied without a magnet. Material details are typical for the family; confirm exact dimensions and sizing from the datasheet, which we can provide 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
Select the 16 mm bore when the task needs roughly 100.5 N of push force at 0.5 MPa double acting (the pull side is a little lower); step up or down a bore if the thrust does not match. Choose MKJ over standard MD when rod rotation must be prevented. This SKU is double acting with a 30 mm stroke, inside the bore 16 maximum of 50 mm, plus a 20 mm adjustable range on top.
With no trailing S, the magnet is not fitted on this SKU; add the S version if you need magnetic-switch position sensing. The thread is PT as standard and G is available. Stay within the bore 16 stroke limit, as the short cover design cautions against an over-long stroke, and send side-load questions to us to confirm from the datasheet.
Applications
Adjustable lift-and-locate pins
Raise and lower locating pins under a workpiece where the pin must present a flat, untwisted face. The no-rotating plate holds the pin orientation, and the 20 mm adjustable range trims the lift height around the 30 mm base stroke.
Product diverter on narrow conveyors
Push small products off a narrow conveyor where mounting space is limited. The 6-direction fixing and side-by-side bodies fit the tight frame, and the no-rotating rod keeps the pushing paddle aligned with the product flow.
Tunable test-fixture actuator
Press or position parts in a compact test station where the stroke must be dialed in per product revision. The 20 mm adjustable range on the 30 mm stroke allows tool-free retuning without swapping cylinders.
FAQ
Does MKJ16X30-20 include a magnet for switch sensing?
No. The model code ends in 20 with no trailing S, so this SKU is supplied without a magnet. The magnetic-switch slots are still machined around the body, and an S-suffixed version of the same bore and stroke is available if you want position sensing. Thread is PT on this SKU, with G offered as an option.
Why choose the MKJ no-rotating body over a standard MD cylinder?
The MK family adds a no-rotating plate, brass bushing and fixed rod, so the piston rod cannot turn, which matters for flat paddles, stops and orientation-sensitive contacts. The MD family is the standard version where rod rotation is acceptable. Both share the multi-mount square body that fixes from 6 directions and mounts side by side; confirm dimensions from the datasheet on request.
