Airtac MKJ Adjustable Cylinder MKJ6X30-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ6X30-10 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 MKJ6X30-10
The MKJ6X30-10 is an AirTAC adjustable-stroke 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 with neighbours to save panel space. With a 6 mm bore in double-acting configuration it delivers a theoretical push thrust of about 14.1 N at 0.5 MPa, suited to light clamping, locating and gating jobs, and the stroke can be set anywhere within its 30 mm main stroke plus a 10 mm adjustable range. Cushioning is provided by an elastic bumper rather than an air cushion.
This is a genuine AirTAC part from the MK family, which means a no-rotating plate, brass bushing and fixed rod stop the piston rod from turning - unlike the standard MD family where rotation is allowed. As the SKU shows, this model has no built-in magnet; choose the S suffix if you need one. We can 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 where the theoretical push thrust of about 14.1 N at 0.5 MPa (pull side about 10.6 N) is enough for the job. MK keeps the rod from rotating, while MD allows rotation - pick MK for orientation-sensitive tooling. This is a double-acting adjustable-stroke (MKJ) model: air drives the rod both ways and you can trim the effective stroke by 10, 20 or 30 mm. The 30 mm stroke sits near the top of the bore 6 double-acting table (up to 35 mm), so do not stretch beyond the listed range; the covers are short, and over-long strokes reduce stability. No magnet is fitted (no S suffix). The thread is PT as standard; G threads are available on request. Side-load ratings and dimensions come from the datasheet - ask us.
Applications
Small-parts clamping
A 6 mm multi-mount cylinder bolted top or bottom on a fixture holds tiny components in place during light assembly, with the 10 mm adjustable range fine-tuning the clamp position without re-drilling.
Non-rotating pick-and-place
The MK no-rotating plate and fixed rod keep the end tool facing the same way during short horizontal transfers, so gripped parts stay oriented between stations.
Gate and stopper on small conveyors
Mounted side by side along a compact conveyor, these square-body cylinders raise and lower a stopper to gate or index small parts, fixed from whichever of the 6 mounting faces suits the frame.
FAQ
What does the -10 at the end of MKJ6X30-10 mean?
MKJ is the AirTAC adjustable-stroke no-rotating multi-mount cylinder. The code reads as a 6 mm bore, 30 mm main stroke, with a 10 mm adjustable range added on top, so the effective stroke can be trimmed within that extra span. The -20 version adds a 20 mm adjustable range instead, and the S suffix (as in MKJ6X30-10S) means a built-in magnet.
How does the no-rotating feature work, and where do I find the dimensions?
In the MK family a fixed rod, brass bushing and no-rotating plate stop the piston rod from turning, which keeps tooling plates and grippers oriented. The square body also fixes from 6 directions so cylinders can sit side by side to save space. Overall dimensions vary with stroke and the side-load limit is a datasheet figure, so confirm both from the datasheet - we can supply it on request.
