Airtac MKJ Adjustable Cylinder MKJ25X35-10S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ25X35-10S 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 MKJ25X35-10S
The AirTAC MKJ25X35-10S is a compact square-body multi-mount cylinder that can be fixed from six directions (front, back, left, right, top and bottom) and mounted side by side to save space, with magnetic-switch slots around the body and high guide precision, so no added lubricant is needed. This no-rotating, adjustable-stroke variant is double acting with a 25 mm bore, a 35 mm base stroke and a 10 mm adjustable range, delivering a theoretical push force of 245.4 N at 0.5 MPa (206.2 N on the pull side), running 30-500 mm/s and cushioned by a bumper.
This is a genuine AirTAC part from the MK family, the no-rotating multi-mount range: a fixed rod and no-rotating plate stop the piston rod from turning, unlike the standard MD family. The trailing S means the unit is supplied with a magnet, allowing switch actuation in the body slots. It operates on air filtered to 40 um, withstands 1.5 MPa (215 psi) proof pressure and runs from -20 to 70 C. 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
Select the bore for thrust: 25 mm delivers 245.4 N of theoretical push force at 0.5 MPa double acting, with 206.2 N on the pull side. Choose MKJ when the rod must not rotate and a fine end-position setting is needed; MK is the fixed-stroke no-rotating version and MD the standard family where rotation is acceptable. For the 25 mm bore, strokes run up to 60 mm, and this SKU combines a 35 mm base stroke with a 10 mm adjustable range. Because the covers are compact, avoid stretching the stroke beyond what the body was designed for. This unit includes the S magnet option and PT thread with M5x0.8 ports; G thread is the alternative. Route side-load figures to us or the datasheet.
Applications
Clamp arm actuation
Drive a small clamp arm from the side of a fixture, where the non-rotating plate keeps the arm square to the part and the 10 mm adjustment trims the clamp position.
Conveyor stopper
Bolt the cylinder to a conveyor frame to raise a stopper or gate, fixing it from the top, side or bottom to suit the frame and fine-tuning the stroke end position.
Indexing plate drive
Advance an indexing plate a fixed increment on a rotary table, with the no-rotating plate holding orientation and the magnet confirming the completed move.
FAQ
How much stroke can I actually set on the MKJ25X35-10S?
The base stroke is 35 mm and the J suffix adds a 10 mm adjustable range on top, so the effective stroke can be set anywhere up to about 45 mm. Strokes for the 25 mm bore are catalogued up to 60 mm, but the compact covers mean an over-long stroke should be avoided; check the datasheet for exact body dimensions at your stroke.
How much side load can this cylinder take?
A specific allowable side-load figure is not listed here and should be confirmed from the datasheet before you put the rod in bending. The MK no-rotating plate and guide design give high guide precision, but for meaningful side loads we recommend checking the datasheet or contacting us for sizing help.
