Airtac MDJ Adjustable Cylinder MDJ20X60-20S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X60-20S 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 MDJ20X60-20S
The MDJ20X60-20S 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 carries a magnet (trailing S), so the switch slots around the body can be used for position sensing. 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. Trailing S means this version includes the magnet; thread is PT by default or G on request. For side-load limits, confirm from the datasheet or ask us.
Applications
Adjustable end-stop setting
Set a precise end stop on a small assembly station, using the 20 mm adjustable range to dial in stroke length while the magnet in the switch slots reports position.
Slide transfer in tight cells
Push a small slide or transfer table sideways in a tight machine cell, fixing the square body from any of six directions and parking cylinders side by side.
Lab sampler and tester actuation
Actuate a compact sampler or test-head mechanism in lab equipment, where the 60 mm stroke with 20 mm adjustment covers varied sample positions at about 157.1 N push at 0.5 MPa.
FAQ
What does the adjustable stroke on the MDJ20X60-20S let me do?
It gives a 60 mm base stroke plus an extra 20 mm adjustable range, so you can set the effective stroke anywhere in that window without swapping cylinders. Note that 60 mm is the maximum double-acting stroke for a 20 mm bore and the covers are short, so do not spec an over-long stroke.
What does the S in MDJ20X60-20S mean, and what pressure does it run at?
The trailing S means the cylinder is built with a magnet for the magnetic-switch slots around the body. The MD double-acting family operates at 0.15-1.0 MPa (22-145 psi) with air filtered to 40 um, giving about 157.1 N theoretical push at 0.5 MPa on a 20 mm bore.
