Airtac MKJ Adjustable Cylinder MKJ25X25-10S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ25X25-10S is a genuine MK multi-mount cylinder (adjustable stroke), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 245.4 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 MKJ25X25-10S
The MKJ25X25-10S is an adjustable-stroke multi-mount cylinder from AirTAC's MK family. Its compact square body can be fixed from 6 directions (front, back, left, right, top and bottom) and cylinders can be mounted side by side to save space, with magnetic-switch slots machined around the body. With a 25 mm bore and a 25 mm stroke plus a 10 mm adjustable range, this double-acting cylinder delivers a theoretical push thrust of 245.4 N at 0.5 MPa, and cushioning is provided by a bumper rather than an air cushion. It runs on air filtered to 40 um, handles proof pressure of 1.5 MPa (215 psi), operates at 0.15-1.0 MPa (22-145 psi) and from -20 to 70 C (0 to 150 C only with the optional high-temperature seal material), with speeds of 30-500 mm/s.
This is a genuine AirTAC part. MK-family cylinders are no-rotating: a fixed rod, plate and brass bushing stop the piston rod from turning, which suits jobs where the rod orientation must stay put. The trailing S in this SKU means the magnet is fitted. 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 25 mm bore when you need around 245.4 N of push thrust at 0.5 MPa (the pull side is lower). MK gives you a no-rotating rod; pick the MD family instead if rotation is allowed. This MKJ is double acting with a 25 mm stroke plus a 10 mm adjustable range on top of the bore's 60 mm maximum. The trailing S means the magnet is included, and the thread is PT (a G thread version is available without the S). Because the covers are short, avoid specifying an over-long stroke; for side-load figures, route to us.
Applications
Non-rotating small-parts clamp
Clamps small parts in a machining fixture while the no-rotating plate keeps the rod square to the workpiece, with the 245.4 N push at 0.5 MPa holding the part steady.
Pick-and-place with a fixed plate
Drives a pick plate on an assembly line where the rod must not turn; the side-by-side multi-mount body fits the tight spacing between adjacent stations.
Indexing stopper on a conveyor
Extends against parts on a conveyor to stop and index them, with the adjustable range letting you fine-tune the stop position and 6-way fixing to suit the frame.
FAQ
What does the -10 in MKJ25X25-10S mean?
MKJ is the adjustable-stroke double-acting variant of the MK multi-mount family. The code decodes as a 25 mm bore, a 25 mm stroke, and a 10 mm adjustable range added on top of the stroke. Adjustments of 10, 20 or 30 mm are offered. The trailing S means this unit carries the magnet.
How do I mount this cylinder and how far can the rod be side-loaded?
The square body can be fixed from 6 directions (front, back, left, right, top and bottom) and units can sit side by side to save space. Because the covers are short, keep the stroke proportionate and avoid over-long strokes. Permissible side load and exact dimensions depend on the stroke, so confirm them from the datasheet or ask us.
