Airtac MKJ Adjustable Cylinder MKJ32X25-30
The AirTAC Airtac MKJ Adjustable Cylinder MKJ32X25-30 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 MKJ32X25-30
The MKJ32X25-30 is an AirTAC adjustable-stroke multi-mount cylinder: a compact square body that fixes from six directions - front, back, left, right, top and bottom - and sits side by side with other cylinders where panel space is tight. It is double acting with a 32 mm bore and a 25 mm stroke, extended by a 30 mm adjustable range for fine stroke setting in the fixture. At 0.5 MPa the bore delivers a theoretical push thrust of 402.1 N, and the cushion is a bumper.
This is a genuine AirTAC MK-series part with a no-rotating plate, bushing and fixed rod that keep the piston rod from turning, so mounted tooling holds its orientation. This SKU has no S suffix, so no magnet is fitted; without it, magnetic switches cannot sense piston position. Switch slots run around the body should you need a magnet version. 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.
How to choose
The 32 mm bore is the thrust leader of this range: about 402.1 N pushing and 345.6 N pulling at 0.5 MPa, double acting. Choose MK over MD when rotation must be prevented - MD is the standard build where a little rotation is fine. The J build adds a 10, 20 or 30 mm adjustable range over the 25 mm stroke; bore 32 double-acting cylinders top out at 60 mm in the standard table, so stay well inside that short-cover limit. This SKU omits the S, meaning no magnet - pick an S version if switch feedback is needed. The thread is PT as standard, with G available. Route any side-load requirement to us and we will confirm it from the datasheet.
Applications
Small-parts ejection
Banked side by side on an assembly bench, each cylinder pushes finished small parts off a nest; the adjustable range lets operators dial the eject distance per part size.
Indexing dial fixture
On a rotary indexing table, the no-rotating rod advances a detent pin squarely into each station, with the 30 mm adjustment absorbing fixture tolerance.
Slide gate actuation
Fixed from the top or side of a chute, the cylinder drives a slide gate to divert product between lanes while the plate keeps the gate plate from rotating.
FAQ
Does MKJ32X25-30 include a position-detection magnet?
No. This SKU has no S suffix, so it is supplied without a magnet and magnetic switches will not sense the piston. If you need switch feedback, select the S version; the switch slots run around the body on all units.
How far can I safely stretch the stroke on this cylinder?
The base stroke is 25 mm with a 30 mm adjustable range, and bore 32 double-acting cylinders are tabulated up to 60 mm. Because the covers are short, avoid running close to the maximum; confirm your exact dimension and any side load with us from the datasheet before finalising the fixture.
