Airtac MDJ Adjustable Cylinder MDJ20X60-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X60-10S 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.

About the Airtac MDJ Adjustable Cylinder MDJ20X60-10S
The MDJ20X60-10S is an adjustable-stroke multi-mount cylinder with a 20 mm bore, a 60 mm base stroke and an extra 10 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) for position-sensing switch slots. 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 adds a magnet; thread is PT by default or G on request. For side-load limits, confirm from the datasheet or ask us.
Applications
Small-parts clamping
Clamp small workpieces on an assembly fixture where the 20 mm bore gives about 157.1 N push at 0.5 MPa and the square body fixes from six directions to fit tight tooling plates.
Jig positioning
Position jigs on a machining or welding line with the 60 mm stroke plus 10 mm adjustment, tuning the end position precisely without changing the whole cylinder.
Gate and stopper actuation
Actuate a compact gate or stopper beside a conveyor, mounting units side by side where panel space is limited and switch slots in the body track gate position via the magnet.
FAQ
What does the 10 in MDJ20X60-10S mean?
It is the adjustable-stroke range. The cylinder has a 60 mm base stroke plus an extra 10 mm of adjustment, so the effective end position can be set anywhere up to 70 mm. The MDJ series offers a 10, 20 or 30 mm adjustable range on top of the base stroke.
How long can the stroke be on a 20 mm bore, and how do I mount it?
For double acting, the 20 mm bore goes up to 60 mm stroke, which is the maximum for this model; the covers are short, so avoid specifying an over-long stroke. The square body fixes from six directions (front, back, left, right, top and bottom) and can be mounted side by side. Exact dimensions and allowable side load should be confirmed from the datasheet.
