The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X70-50S 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 MKJ32X70-50S is an adjustable-stroke, no-rotating multi-mount cylinder with a square body that fixes from 6 directions - front, back, left, right, top and bottom - so multiple units fit side by side in compact machines. This double-acting model combines a 32 mm bore and 70 mm stroke with a 50 mm adjustable range, generates up to 402.1 N of theoretical push force at 0.5 MPa, and cushions with a bumper.
This is a genuine AirTAC part. The MK family's no-rotating plate, brass bushing and fixed rod stop the piston rod from turning, unlike the standard MD family where rotation is allowed. The trailing S confirms this SKU ships with a magnet; it operates at 0.15-1.0 MPa through 1/8" PT ports. We confirm exact 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.
At 32 mm the bore delivers 402.1 N theoretical push (345.6 N pull) at 0.5 MPa - pick it for demanding clamping or pressing tasks. Choose MK rather than MD when the rod must stay rotationally locked, and double acting for powered return. The J suffix adds an adjustable stroke - here 50 mm on top of the 70 mm fixed stroke - the S suffix means the magnet is included, and thread is PT by default with G selectable. Watch the short cover when specifying long travel, and route any side-load or dimension checks to the datasheet or to us.
Units fixed from the top and sides of a palletizer frame square up cartons before stacking, with the no-rotating rod keeping the push plate aligned shot after shot.
The compact body mounts flush along a conveyor line to shift product between lanes, and the adjustable stroke sets the exact gate travel the layout needs.
Side-by-side mounting packs several clamping points into a tight fixture, applying 402.1 N push force to hold housings steady during a light press or staking step.
The J version offers an adjustable stroke on top of the fixed 70 mm stroke; the -50 code specifies a 50 mm adjustable range, giving extra tuning latitude for positioning and stopper tasks. The S suffix means the magnet for switch detection is included.
Confirm the permitted stroke for the bore, overall dimensions for your stroke, and any allowable side-load figures from the datasheet, since the short multi-mount cover limits stroke length. Mounting is flexible across 6 directions, and we can help verify sizing on request.
