Airtac MDJ Adjustable Cylinder MDJ20X5-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X5-10S 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 MDJ20X5-10S
The MDJ20X5-10S 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 with other cylinders to save space. This adjustable-stroke, double-acting model has a 20 mm bore and a 5 mm base stroke, plus an extra 10 mm adjustable range you can set on the machine. At 0.5 MPa it delivers about 157.1 N of theoretical push force, enough for light clamping and positioning work, and it cushions with a bumper rather than an air cushion.
This is a genuine AirTAC part in the standard MD family, where the piston rod is free to turn unless your tooling prevents it; if you need the rod rotation stopped, look at the MK no-rotating family instead. The trailing S in the code means this SKU includes a magnet for magnetic-switch detection. Magnetic-switch slots are provided around the body. We confirm dimensions, overall sizing and mounting details 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.
How to choose
Choose the 20 mm bore when you need roughly 157.1 N of push at 0.5 MPa on the push side; smaller bores give less thrust, larger bores more. The MDJ adjustable-stroke variant adds a 10, 20 or 30 mm adjustable range on top of the base stroke, and this model pairs a 5 mm stroke with a 10 mm adjustable range. Bore 20 double-acting cylinders are listed up to 60 mm of stroke. MD is the standard family (rod rotation allowed); MK is the no-rotating alternative. The trailing S means magnet included; SKUs without an S are supplied without a magnet. Thread is PT by default, with G available as the trailing G option. Keep the stroke modest so the short covers remain effective, and ask us before applying any side load.
Applications
Small-parts clamping
The short 5 mm stroke with a 10 mm adjustable range is well suited to clamping arms that close on small parts in fixtures, with the 20 mm bore giving about 157.1 N of push at 0.5 MPa.
Jig positioning
Fix the square body from any of 6 directions inside a jig and set the exact stop position with the adjustable stroke, mounting several cylinders side by side where space is tight.
Compact gate actuator
Use the side-by-side mounting and switch slots to drive a sliding gate or stopper on a compact line, with the magnet signalling end positions to the controller.
FAQ
What does the adjustable stroke on the MDJ20X5-10S mean?
MDJ is the adjustable-stroke variant of the MD family. This model has a 20 mm bore and a 5 mm base stroke, and the -10 adds a 10 mm adjustable range on top, so the effective stroke can be set within that extra range on the machine.
How do I mount this cylinder on my machine?
The multi-mount square body can be fixed from 6 directions: front, back, left, right, top and bottom, and cylinders can be mounted side by side to save space. Because the body is short, avoid stretching the stroke beyond the design range, and confirm side-load limits and exact dimensions from the datasheet.
