Airtac MKJ Adjustable Cylinder MKJ6X30-30
The AirTAC Airtac MKJ Adjustable Cylinder MKJ6X30-30 is a genuine MK multi-mount cylinder (adjustable stroke), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 14.1 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 MKJ6X30-30
The AirTAC MKJ6X30-30 is an 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. Bodies mount side by side to save space, and magnetic-switch slots surround the body. This 6 mm bore double-acting unit delivers about 14.1 N of theoretical push thrust at 0.5 MPa, covers 30 mm of main stroke plus a full 30 mm adjustable range, and is cushioned by a bumper.
This is a genuine AirTAC part. The MK family differs from the standard MD family by adding a no-rotating plate, bushing and fixed rod that stop the piston rod from turning, so attached tooling keeps its orientation. This SKU has no S suffix, so it is built without a magnet; thread is PT. 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
Choose the 6 mm bore when roughly 14.1 N of push at 0.5 MPa is enough for the job; larger bores give more force. The MKJ prefix means double acting with a 30 mm adjustable range added to the 30 mm stroke, giving the widest trim span in this series. MK prevents rod rotation; MD allows it. Stroke for a 6 mm bore double-acting unit runs up to 35 mm, and the short cover cautions against over-long strokes. This SKU has no magnet; add the S suffix if you need switch detection. Thread is PT, with G available. Confirm side-load limits with us from the datasheet.
Applications
Jig positioning with fine height trim
The 30 mm adjustable range lets a fixture builder dial in exact contact height on a locating jig, while the no-rotating rod keeps the contact tip oriented cycle after cycle.
Pick-and-place ejection
Mounted under a small pick station, the cylinder ejects or lifts tiny components; side-by-side mounting fits multiple units into a compact head plate.
Gate actuation on a compact slide
Fixed from the side of a miniature gate, the double-acting rod opens and closes it with bumper cushioning, and 6-direction fixing simplifies bracket design.
FAQ
How is MKJ6X30-30 different from the standard MD cylinder?
Both are compact multi-mount cylinders, but MK adds a no-rotating plate, bushing and fixed rod that stop the rod from turning, while MD allows rotation. MKJ6X30-30 is also adjustable-stroke: 30 mm of main stroke plus a 30 mm adjustable range, double acting. Note that this SKU, without the S suffix, is built without a magnet.
Can I mount this cylinder from any face of the body?
Yes. The square body is designed to be fixed from 6 directions: front, back, left, right, top and bottom, and units can sit side by side to save space. Keep the stroke within the 6 mm bore double-acting table (up to 35 mm), since the short cover does not suit over-long strokes; exact dimensions and side-load limits come from the datasheet.
