Airtac MKJ Adjustable Cylinder MKJ32X20-10S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X20-10S 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 MKJ32X20-10S
The AirTAC MKJ32X20-10S is a no-rotating adjustable-stroke multi-mount cylinder: a compact square-body air cylinder that can be fixed from six directions (front, back, left, right, top and bottom) and mounted side by side to save space. With a 32 mm bore in double-acting configuration it delivers up to 402.1 N of theoretical push thrust at 0.5 MPa, and a 20 mm base stroke with an added 10 mm adjustable range. Cushioning is provided by a bumper.
This is a genuine AirTAC part in the MK family, which adds a no-rotating plate, brass bushing and fixed rod so the piston rod cannot turn - unlike the standard MD family where rotation is allowed. The trailing S in the model code means this SKU includes a magnet. Dimensions and sizing details can be 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.
How to choose
Choose the 32 mm bore when you need the highest thrust in this range: 402.1 N push at 0.5 MPa (the pull side is lower). MK is the right choice where the rod must not rotate; MD suits applications that tolerate rotation. The MKJ variant is double acting with a 10, 20 or 30 mm adjustable stroke added on top of the base stroke - here a 20 mm stroke with a 10 mm adjustment. The trailing S orders the magnet version; without it the cylinder has no magnet. Port thread is PT by default, with G available as an option. Note the short cover: keep the stroke within the bore's table rather than stretching it, and confirm side-load capability with us from the datasheet.
Applications
Small-parts clamping
The no-rotating rod keeps clamp pads flat against the part, while the 6-direction fix lets the 32 mm body bolt wherever the clamp point sits on a tight fixture.
Weld fixture positioning
Side-by-side mounting of identical MKJ bodies lets a jig builder line up multiple adjustable stops and clamps on one rail, each trimmed within its 10 mm adjustment range.
Press-fit helper station
The 402.1 N push at 0.5 MPa suits light press or crimp operations where the plate-held rod must stay oriented and the compact body mounts under a low header plate.
FAQ
What does the adjustable stroke in MKJ32X20-10S mean?
MKJ is the adjustable-stroke MK variant: it is double acting, and the code MKJ32X20-10S decodes as a 32 mm bore, 20 mm base stroke plus a 10 mm adjustable range. MKJ models can also be ordered with 20 or 30 mm adjustment, and the trailing S shows this SKU includes a magnet.
How does the no-rotating feature work, and where are the mounting limits?
MK cylinders add a no-rotating plate, brass bushing and fixed rod so the rod cannot turn under load - the standard MD family does allow rotation. Keep the stroke within the bore's table because of the short cover, and confirm side-load figures and overall dimensions from the datasheet.
