The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X70-30S 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.
The AirTAC MKJ32X70-30S is an adjustable-stroke, no-rotating multi-mount cylinder whose compact square body fixes from 6 directions - front, back, left, right, top and bottom - letting units mount side by side where space is tight. This double-acting model pairs a 32 mm bore and 70 mm stroke with a 30 mm adjustable range, produces up to 402.1 N of theoretical push force at 0.5 MPa, and uses a bumper for cushioning.
This is a genuine AirTAC part. As an MK-family cylinder it adds a no-rotating plate, brass bushing and fixed rod that hold the rod from turning, unlike the standard MD family where rotation is permitted. The trailing S in the code confirms this SKU includes a magnet; operating pressure is 0.15-1.0 MPa with 1/8" PT ports. Exact dimensions and sizing are confirmed 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.
The 32 mm bore gives you 402.1 N theoretical push (345.6 N pull) at 0.5 MPa - the strongest thrust in this range. Select MK over MD whenever the rod must not rotate, and double acting when air is supplied to both sides. The J suffix adds the adjustable stroke - here 30 mm on top of the fixed 70 mm - the S suffix adds the magnet, and PT thread is standard with G offered as an option. Remember the short cover restricts maximum stroke, so check your travel needs and send any side-load questions to the datasheet or our team.
Mounted side by side on a welding or assembly jig, each unit locates a workpiece feature precisely, and the no-rotating rod keeps locator pins square to the fixture.
Fixed from the top of a rotary or linear indexing table, the cylinder halts each station in register, with the 30 mm adjustable range fine-tuning the stop position.
The square body bolts to the bottom of a slide-gate frame for compact vertical actuation, moving a diverter plate without any rod twist over long runs.
MKJ keeps the rod from rotating via a no-rotating plate, brass bushing and fixed rod, fixes from 6 directions to save space beside other units, and adds an adjustable stroke - here 30 mm on top of the 70 mm fixed stroke - so you can trim the effective travel.
The short cover of the multi-mount design limits how long the stroke can run for a given bore, so verify the permitted stroke range and any side-load figures for this model from the datasheet before specifying it.
