Airtac MKJ Adjustable Cylinder MKJ32X30-20S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X30-20S 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 MKJ32X30-20S
The MKJ32X30-20S is a genuine AirTAC adjustable-stroke multi-mount cylinder with a compact square body that can be fixed from 6 directions (front, back, left, right, top and bottom) so units can be mounted side by side to save space. With a 32 mm bore and a 30 mm base stroke plus a 20 mm adjustable range, it delivers about 402.1 N of theoretical push force at 0.5 MPa, enough for firm clamping and positioning in tight footprints. Cushioning is a bumper, and magnetic-switch slots run around the body for position sensing.
This MK-family model is no-rotating: a fixed rod and plate stop the piston rod from turning, so the attached tooling keeps its orientation. It is double acting, includes the magnet as the SKU shows (trailing S), and uses PT ports. We confirm dimensions, rod detail and sizing from the AirTAC 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 32 mm bore when you need the largest thrust in this series, about 402.1 N push (345.6 N pull) at 0.5 MPa, within an operating range of 0.15-1.0 MPa. MK means rotation is prevented at the rod, where the MD family would allow it; MKJ adds a 10/20/30 mm adjustable range, here 20 mm, on top of the 30 mm base stroke. The trailing S means this SKU includes the magnet; without S the magnet is omitted. Thread is PT as standard (G available). Keep the stroke short, because the compact cover limits how long a stroke fits; confirm side-load figures from the datasheet.
Applications
Small-parts clamping
Mounts side by side on a fixture plate and the no-rotating rod keeps the clamp pad square to the part while delivering about 402.1 N push at 0.5 MPa.
Gate and stopper control
The 6-direction body fixes horizontally on a conveyor frame and the 30 mm stroke plus 20 mm adjustment sets the exact extend position to stop or divert product.
Jig positioning
Top or bottom fixing slots let the cylinder pin workpieces into a machining jig, with the adjustable range tuning the final rest position without shims.
FAQ
What does the code MKJ32X30-20S mean?
MKJ is the no-rotating adjustable-stroke variant, 32 is the bore in mm, 30 is the base stroke, 20 is the adjustable range added on top, the trailing S means the magnet is included, and with no G the ports are PT thread. MK double-acting cylinders of this bore operate at 0.15-1.0 MPa (22-145 psi) with about 402.1 N theoretical push at 0.5 MPa.
Where can I mount this cylinder?
The square body can be fixed from 6 directions: front, back, left, right, top and bottom, so several units can sit side by side to save space. Keep the stroke short because of the compact cover, and confirm exact dimensions and side-load limits from the datasheet.
