Airtac MDJ Adjustable Cylinder MDJ20X60-20
The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X60-20 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.

About the Airtac MDJ Adjustable Cylinder MDJ20X60-20
The MDJ20X60-20 is an adjustable-stroke multi-mount cylinder with a 20 mm bore, a 60 mm base stroke and an extra 20 mm of adjustment on top. The compact square body fixes from six directions (front, back, left, right, top and bottom), so units can be mounted side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubricant. Double acting with a 20 mm bore, it gives about 157.1 N of theoretical push at 0.5 MPa (131.9 N on the pull side), with cushioning by a bumper.
This is a genuine AirTAC part. The MD family is the standard series; if you need the piston rod prevented from turning, choose the MK family instead. This SKU is without a magnet, as shown by the absence of the trailing S in the model code. Medium is air filtered to 40 um, operating pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to 70 C (0-150 C only with the optional high-temperature seal material). We confirm 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
Choose the bore for thrust: at 0.5 MPa a 20 mm bore gives about 157.1 N push (131.9 N pull) in double acting. MD allows rod rotation; MK prevents it. Acting type options are double, single push (MSD), single pull (MTD), double rod (MDD) and adjustable (MDJ), which adds a 10/20/30 mm range over the base stroke. This 60 mm stroke sits at the 20 mm bore maximum for double acting; the covers are short, so avoid over-long strokes. No magnet on this SKU; add a magnet by choosing the S version. Thread is PT by default or G on request. For side-load limits, confirm from the datasheet or ask us.
Applications
Indexing on rotary tables
Index parts on a small rotary table or dial plate, using the 60 mm stroke plus 20 mm of adjustment to fine-tune the stop position without repositioning the cylinder body.
Pick-and-place on compact heads
Drive a small pick-and-place head where panel depth is tight; the six-direction fixing lets the cylinder mount top, bottom or side in the same footprint.
Fixture clamping
Clamp lightweight workpieces in a test or assembly fixture with about 157.1 N push at 0.5 MPa from the 20 mm bore, bumper cushioning the clamp motion.
FAQ
How does MDJ20X60-20 differ from MDJ20X60-20S?
Only the magnet. The trailing S in a model code means the cylinder is built with a magnet for position-sensing switches; MDJ20X60-20 without the S is built without a magnet. Everything else, including the 60 mm base stroke and the 20 mm adjustable range, is the same.
Can I set any stroke within the range, and what else should I check?
The MDJ adjustable-stroke design gives a 60 mm base stroke with an extra 20 mm of adjustment, and 60 mm is already the maximum stroke for a 20 mm double-acting bore, so the covers are short. Avoid over-long strokes, and confirm exact dimensions and allowable side load for your layout from the datasheet.
