Airtac MDJ Adjustable Cylinder MDJ25X50-50
The AirTAC MDJ Adjustable Cylinder MDJ25X50-50 is a genuine MD multi-mount cylinder (double rod, adjustable stroke), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 245.4 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ25X50-50
The MDJ25X50-50 is a 25 mm bore, 50 mm stroke adjustable-stroke multi-mount cylinder from AirTAC. As a multi-mount body it can be fixed from 6 directions - front, back, left, right, top and bottom - and multiple units mount side by side to save space, with magnetic-switch slots formed around the body. This double-acting version develops about 245.4 N of theoretical push thrust at 0.5 MPa, and the cushion is a bumper. The adjustable-stroke design lets you fine-set the working stroke for precise end positions.
This is a genuine AirTAC part in the standard MD family, where rod rotation is not restricted (choose the MK family if you need a no-rotating rod). This SKU is built without a magnet, so it does not carry the trailing S. Medium is air filtered to 40 um; operating pressure is 0.15-1.0 MPa (22-145 psi); speed is 30-500 mm/s; temperature is -20 to 70 C. Dimensions and sizing for this stroke are per the datasheet - we confirm them 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
Bore sets thrust: this 25 mm bore gives about 245.4 N theoretical push at 0.5 MPa - step up to 32 mm for about 402.1 N or down to 20 mm for about 157.1 N. MD keeps rotation allowed; MK prevents it. Acting type: this is a double-acting adjustable-stroke (MDJ) unit; single push (MSD), single pull (MTD), double rod (MDD) and fixed-stroke MD are the alternatives. The 50 mm stroke sits inside the bore 25 table (up to 60 mm), with the 50 mm adjustable range shown in the code added on top - confirm exact adjustment from the datasheet. Keep strokes conservative: the short cover warns against over-long strokes, and side-load limits should be confirmed with us. Magnet is optional (trailing S); this SKU has none. Port is M5x0.8 with PT thread, or choose G.
Applications
Adjustable end-stop on a test bench
Bolted to a bench plate from the side, the cylinder advances a probe or stop to a set position against a small workpiece. The 50 mm adjustable range lets the technician re-position the stop between tests without changing hardware.
Small-parts clamp with settable travel
Mounted side by side on a fixture plate, the units clamp small housings during an assembly step. The 25 mm bore push at 0.5 MPa handles light clamping, the bumper softens contact, and the adjustable stroke sets exact pad travel per part.
Palletizer light part pusher
Fixed to a small palletizing or sorting cell frame, the cylinder pushes light cartons or trays off a lane. The compact body saves space between lanes, the 6-direction fixing suits frame mounting, and the adjustable range sets the push distance.
FAQ
How much force does the 25 mm bore deliver, and when should I change bore?
At 0.5 MPa this double-acting cylinder gives about 245.4 N of theoretical push. If your job needs more, move to the 32 mm bore for about 402.1 N; if less, the 20 mm bore gives about 157.1 N. These are theoretical values - confirm the application against the datasheet.
What should I check before choosing a long or adjustable stroke?
Stay within the stroke table for the bore (25 mm bores go up to 60 mm double acting) and remember the short cover cautions against over-long strokes. Side-load capacity is not stated here as a number and overall dimensions vary with stroke, so confirm both from the datasheet or with us before ordering.
