Airtac MKJ Adjustable Cylinder MKJ10X30-30S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ10X30-30S is a genuine MK multi-mount cylinder (adjustable stroke), 10 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 39.3 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 MKJ10X30-30S
The MKJ10X30-30S is an AirTAC MK-family multi-mount cylinder: a compact square-body actuator you can fix from 6 directions (front, back, left, right, top and bottom) and mount side by side with neighbours to save panel space. Magnetic-switch slots are machined around the body, guide precision is high, and no added lubricant is needed. This unit is double acting, no-rotating, with a 10 mm bore and a 30 mm stroke that carries an extra 30 mm of adjustable stroke, so the effective stroke can be fine-trimmed in place. At 0.5 MPa the bore-10 push side gives about 39.3 N of theoretical thrust, and cushioning is a bumper.
This is a genuine AirTAC part. The MK family prevents rod rotation with a fixed rod, no-rotating plate and brass bushing, while the MD family is the standard version that allows rotation - choose MK when the load must not turn. Magnet is fitted on this SKU, as shown by the trailing S, so position switches can be read from the body slots. Operating pressure is 0.2-1.0 MPa (28-145 psi) for this bore, the medium is air filtered to 40 um, and temperature range is -20 to 70 C (0-150 C only with the optional high-temperature seal material). 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 sets thrust: this 10 mm bore delivers about 39.3 N push at 0.5 MPa (double acting), so move to a larger bore if your work needs more force. MK is the no-rotating family - rod rotation is prevented - while MD is the standard family where rotation is allowed. Acting type: this is a double-acting MKJ adjustable-stroke unit; single-acting push (MSK) and pull (MTK), double-rod (MKD) and standard (MK) variants also exist. The 30 mm stroke sits inside the bore-10 double-acting table (up to 35 mm), and the J variant adds 10, 20 or 30 mm of adjustable range on top - this SKU adds 30 mm. Keep the stroke short relative to the cover: an over-long stroke on a compact body is a common mis-selection. The trailing S means a magnet is fitted for switch sensing; thread on this SKU is PT (G is available). Side-load capacity is not quoted here - ask us and we will check the datasheet.
Applications
Small-parts clamping
Clamp small components in test or assembly fixtures; the no-rotating rod keeps the clamp pad square and end-of-stroke can be sensed via the fitted magnet.
Gate and stopper control
Actuate a small gate or stopper pin on a transfer line, fixing the compact body from the side or bottom and trimming the adjustable range to the gate travel.
Lab sample handling
Position samples in compact lab automation where space is scarce; side-by-side mounting and switch slots let several axes sit in one tight frame.
FAQ
What does the S at the end of MKJ10X30-30S mean?
The trailing S means a magnet is fitted to the piston, so magnetic switches can be read from the slots around the body. Without the S there is no magnet. The rest of the code: MKJ is the no-rotating double-acting adjustable-stroke variant, 10 mm bore, 30 mm base stroke with a 30 mm adjustable range, PT thread.
Can I mount this cylinder in any orientation?
Yes - the multi-mount body fixes from 6 directions: front, back, left, right, top and bottom, and units can be mounted side by side to save space. The no-rotating plate and fixed rod stop the rod turning under load. For exact mounting dimensions, stroke limits and side-load figures, we confirm from the datasheet on request.
