Airtac MKJ Adjustable Cylinder MKJ32X50-30
The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X50-30 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 MKJ32X50-30
The MKJ32X50-30 is an adjustable-stroke, no-rotating multi-mount cylinder with a 32 mm bore and 50 mm base stroke. The compact square body fixes from six directions (front, back, left, right, top and bottom) and can be mounted side by side to save space, with magnetic-switch slots around the body and high guide precision. As a double-acting cylinder it delivers a theoretical push force of 402.1 N at 0.5 MPa (345.6 N on the pull side), runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), and cushions with a bumper. The generous 30 mm adjustable range on top of the 50 mm stroke gives the widest tuning window in this series.
This is a genuine AirTAC part from the MK family, where a fixed rod, plate and brass bushing stop the piston rod from turning - unlike the standard MD family, where rod rotation is allowed. This SKU is listed without the magnet option; the magnet is available on the S versions. Typical materials include an aluminium-alloy body, piston and covers with a stainless or S45C rod and NBR seals, but bore-specific detail should be confirmed from the datasheet. 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
The 32 mm bore gives the highest thrust in this series - 402.1 N push at 0.5 MPa double acting - so select it where firm clamping or pressing force is needed. Choose MKJ over MD when the rod must not rotate; choose MD when rotation is acceptable. This is a double-acting unit. The 50 mm base stroke sits within the bore 32 table (up to 60 mm), and the adjustable-stroke design adds a 30 mm range on top of it - the widest of the 10/20/30 mm options, useful when the exact end position may change between product changeovers. Keep strokes modest: the covers are compact, so avoid specifying an over-long stroke, and confirm side-load capacity with us. The listed thread is PT; a G thread version is available. Magnet is only fitted on SKUs carrying the S suffix.
Applications
Case divert and eject
Fixed through a conveyor side rail, the cylinder ejects cartons onto a reject lane, with the 30 mm adjustable range retuned when the packaging size changes.
Assembly-station stopper
Bolted side by side beneath a pallet line, several MKJ units lift stopper blades to hold pallets at manual assembly stations, and the rod stays square so blades sit flat.
Press-fit positioning
Fixed from the top of a bench fixture, the non-rotating rod presses bushings into housings with 402.1 N of push force at 0.5 MPa, with the stroke endpoint trimmed for each part batch.
FAQ
Why choose the 30 mm adjustable range over 10 or 20 mm on the MKJ series?
The number after the hyphen is the adjustment available on top of the 50 mm base stroke. The 30 mm option gives the widest window for setting the end of stroke, which suits jobs where the endpoint may be retuned between products. The bore 32 double-acting unit still delivers a theoretical 402.1 N push at 0.5 MPa across that range, and magnet is only included on SKUs with an S suffix.
What stops the rod from rotating, and are there limits I should check?
In the MK family a fixed rod, plate and brass bushing prevent the piston rod from turning, so attached tooling stays square without extra guides. The body still fixes from all six directions and mounts side by side to save space. Because the covers are compact, avoid an over-long stroke, and confirm side-load capacity and exact dimensions from the datasheet before applying offset loads to the rod.
