The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X50-10S is a genuine MD multi-mount cylinder (adjustable stroke), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact.
The MDJ20X50-10S is an AirTAC multi-mount cylinder: a compact square-body actuator that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side to save space. This adjustable-stroke, double-acting model has a 20 mm bore, a 50 mm base stroke and a 10 mm adjustable range for tuning the stroke on the machine. At 0.5 MPa it produces about 157.1 N of theoretical push force, and it cushions with a bumper rather than an air cushion.
This is a genuine AirTAC part in the standard MD family, so the rod is free to rotate unless your fixture prevents it; the MK no-rotating family is the alternative when rotation must be stopped. The trailing S in the code means this SKU includes a magnet for magnetic-switch sensing, and slots for the switches run around the body. We confirm dimensions 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.
Pick the 20 mm bore for about 157.1 N of push-side thrust at 0.5 MPa; move to a larger bore for more force. MDJ adjustable-stroke cylinders add a 10, 20 or 30 mm adjustable range on top of the base stroke, and this model combines a 50 mm stroke with a 10 mm adjustable range, within the 60 mm maximum listed for bore 20. Choose MD if rod rotation is acceptable and MK if it is not. Acting choices span double acting, single push, single pull, double rod and adjustable-stroke. The S suffix here means magnet included. Thread is PT by default with G available. Avoid over-long strokes on the short-cover design, and ask us about side-load limits before loading the rod laterally.
Use the 50 mm stroke with 10 mm of adjustment and the built-in magnet to lift parts a set distance for sensing or inspection, with 6-direction fixing simplifying bracket design.
The 20 mm bore gives about 157.1 N of push at 0.5 MPa for clamping fixtures, and side-by-side mounting lets multiple clamp cylinders share one compact manifold plate.
Fix the square body from above or below a conveyor to raise and lower a stopper blade, with the magnet confirming the gate position to the line controller.
At 0.5 MPa, the 20 mm bore delivers about 157.1 N of theoretical push force on the push side; the pull side is lower. Operating pressure for this double-acting MD model is 0.15-1.0 MPa (22-145 psi).
The short-cover design favours modest strokes, so do not stretch the stroke beyond the range listed for the bore; this model provides 50 mm plus a 10 mm adjustable range. Confirm exact per-stroke dimensions and side-load capability from the datasheet.
