Airtac MKJ Adjustable Cylinder MKJ10X15-20
The AirTAC Airtac MKJ Adjustable Cylinder MKJ10X15-20 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 MKJ10X15-20
The MKJ10X15-20 is an AirTAC MKJ 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 sit side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. This double-acting model has a 10 mm bore and 15 mm stroke, and the J suffix adds a 20 mm adjustable-stroke range on top. At 0.5 MPa it gives a theoretical push thrust of 39.3 N, suited to light clamping, positioning and stopping jobs, and the cushion is a bumper.
This is a genuine AirTAC part. The MK family prevents rod rotation with a no-rotating plate, brass bushing and fixed rod, unlike the standard MD family where rotation is allowed. This SKU carries no magnet. Operating pressure is 0.2-1.0 MPa (28-145 psi), the medium is air filtered to 40 um, proof pressure is 1.5 MPa (215 psi), temperature is -20 to 70 C (0 to 150 C only with the optional high-temperature seal material), and the port 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 10 mm bore when your job needs about 39.3 N of theoretical push thrust at 0.5 MPa on the push side; larger bores give more thrust, smaller ones less. Pick MKJ over MD when the rod or a fitted plate must not rotate, and pick the J version when you need a 10, 20 or 30 mm adjustable range added to the 15 mm stroke; here the adjustable range is 20 mm. This is a double-acting cylinder. This SKU has no magnet (the S suffix adds one) and a PT thread (G is available). Note the short body cover: keep the stroke within the bore's table and avoid over-long strokes, and route side-load questions to us.
Applications
Non-rotating gate stopper
Stops product flow on a conveyor line with a fixed plate that will not turn, mounting the compact body vertically or sideways where space is tight.
Jig positioning
Positions and holds small workpieces in a drill or assembly jig, with the 6-way fixing letting the body bolt onto the fixture from whichever face is free.
Small-parts transfer
Pushes or lifts small components between stations in a compact assembly head, with cylinders mounted side by side and the rod kept from rotating.
FAQ
What does the adjustable range in MKJ10X15-20 mean?
MKJ is the adjustable-stroke version of the MK no-rotating cylinder. The base stroke is 15 mm, and the suffix adds a 20 mm adjustable range on top, so the effective stroke can be set within that range. Standard MK models are fixed-stroke; choose MKJ when the end position must be tuned.
How does the no-rotating design help, and where do I find dimensions?
The MK family uses a no-rotating plate, brass bushing and fixed rod so the piston rod cannot turn, which matters when a plate or fitting must hold its orientation. Overall dimensions depend on stroke and are listed per model in the datasheet, which we can confirm for you on request, along with side-load limits.
