Airtac MKJ Adjustable Cylinder MKJ32X25-10
The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X25-10 is a genuine MK multi-mount cylinder (adjustable stroke), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 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 MKJ32X25-10
The MKJ32X25-10 is an AirTAC multi-mount cylinder with a compact square body that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side to save space. It is double acting with a 32 mm bore and a 25 mm base stroke, and the J suffix adds a 10 mm adjustable stroke range so the effective stroke can be trimmed to the job. At 0.5 MPa the push side delivers about 402.1 N of theoretical thrust, and the cushion is a bumper. Magnetic-switch slots are machined around the body and the guide precision is high without added lubrication.
This is a genuine AirTAC part from the MK family, which uses a no-rotating plate, bushing and fixed rod to stop the piston rod turning, unlike the standard MD family where rotation is allowed. This SKU shows no magnet (no S suffix) and PT thread as standard. We confirm overall dimensions and sizing details 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 bore for thrust: at 0.5 MPa double acting, bore 32 gives about 402.1 N push and 345.6 N pull, the highest in this range. MK is the right pick when the rod must not rotate; MD suits applications where rotation is acceptable. This code is double acting with an adjustable stroke: the 25 mm base stroke plus a 10 mm adjustable range stays within the bore 32 limit (up to 60 mm plus the J range). The short square cover means an over-long stroke should be avoided; ask us about side-load limits. This SKU has no magnet; add the S suffix if you need position sensing, and select PT (default) or G thread.
Applications
Non-rotating workpiece clamp
Clamping small parts on fixtures where the rod must stay oriented; the no-rotating plate keeps the rod from turning while the 402.1 N push at 0.5 MPa holds the part firmly.
Pick-and-place alignment
Compact pick-and-place heads need a rod that does not twist; the 6-direction fixing and 10 mm adjustable stroke let the cylinder be tuned to the exact drop position.
Indexing stopper
Used as a stopper on small indexing fixtures, where the side-by-side mounting keeps multiple cylinders in a tight row and the bumper cushions each stop.
FAQ
What does the -10 at the end of MKJ32X25-10 mean?
MKJ is the adjustable-stroke variant of the no-rotating MK family. The code decodes as bore 32, base stroke 25 mm, and a 10 mm adjustable range added on top, so the effective stroke can be set between 25 and 35 mm. The same body is offered with 20 mm or 30 mm adjustable ranges as MKJ32X25-20 or -30.
How does the no-rotating feature work, and how is the cylinder mounted?
The MK family adds a no-rotating plate, bushing and fixed rod that prevent the piston rod from turning, which standard MD cylinders do not do. The square body can be fixed from 6 directions (front, back, left, right, top, bottom) and mounted side by side to save space. Overall dimensions and side-load figures are per stroke, so confirm them from the datasheet or ask us.
