Airtac MKJ Adjustable Cylinder MKJ32X50-40
The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X50-40 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 MKJ32X50-40
The MKJ32X50-40 is an AirTAC multi-mount cylinder with a 32 mm bore, a 50 mm stroke and a 40 mm adjustable-stroke range. As a double-acting, no-rotating cylinder it delivers a theoretical push force of 402.1 N at 0.5 MPa (345.6 N on the pull side), and its cushion is a bumper that absorbs end-of-travel impact. The compact square body fixes from 6 directions - front, back, left, right, top and bottom - so units mount side by side to save space, with magnetic-switch slots around the body.
This is a genuine AirTAC part from the MK family: a fixed rod and no-rotating plate stop the piston rod from turning, so tooling stays square to the body. The SKU has no trailing S, so this cylinder is supplied WITHOUT a magnet; add the S option if position sensing is needed. It runs on air filtered to 40 um at -20 to 70 C, with a proof pressure of 1.5 MPa (215 psi). 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 bore for thrust: at 0.5 MPa this 32 mm bore gives 402.1 N theoretical push (345.6 N pull) in double-acting service. Pick MK over MD when the rod must not rotate; MD is the standard version that allows rotation. Acting options across the MK range include double (MK), single push (MSK), single pull (MTK), double rod (MKD) and adjustable stroke (MKJ, like this model). The stroke must fit the bore's table - bore 32 double acting goes up to 60 mm - and this SKU adds a 40 mm adjustable range on top. This SKU has no magnet; order the S version if you need one, and choose a PT (blank) or G thread. The short covers caution against an over-long stroke, and allowable side load should be confirmed from the datasheet - ask us.
Applications
Gate or stopper
Raise and lower a gate or stopper on a conveyor line, with the no-rotating plate keeping the stop face from twisting as the product bumps against it.
Jig positioning
Position and hold parts in a drilling or welding jig, where the square body fixes from 6 directions and the adjustable stroke sets the hold point.
Compact press fit
Apply a light press or snap-fit action in a small fixture, using the 402.1 N theoretical push at 0.5 MPa and the bumper cushion at end of stroke.
FAQ
Does MKJ32X50-40 include a magnet?
No. The SKU has no trailing S, so this cylinder is supplied WITHOUT a magnet. If you need magnetic-switch sensing, order the corresponding S version instead. In either case the body has magnetic-switch slots around it, and the correct sensor should be confirmed from the AirTAC catalogue or with us.
Why choose a no-rotating multi-mount cylinder here?
The fixed rod and no-rotating plate prevent the rod from turning, which matters for clamps, gates and tooling that must stay square. The square body fixes from 6 directions and mounts side by side to save space in tight machinery. Exact dimensions and allowable side load should be confirmed from the datasheet - contact us and we will provide the figures.
