Airtac MDJ Adjustable Cylinder MDJ20X30-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X30-10S 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 MDJ20X30-10S
The MDJ20X30-10S is an AirTAC multi-mount cylinder: a compact square-body actuator you can fix from 6 directions (front, back, left, right, top and bottom) and mount side by side to save space, with magnetic-switch slots around the body. This adjustable-stroke, double-acting model combines a 20 mm bore and 30 mm stroke with a 10 mm adjustable range, giving about 157.1 N of push thrust at 0.5 MPa, speeds of 30-500 mm/s and a bumper cushion.
It is a genuine AirTAC part in the standard MD family; an MK-family cylinder would instead add a no-rotating plate to stop the rod turning. The trailing S shows this SKU includes the magnet, and the thread is PT. Overall dimensions vary with stroke, so confirm them and any sizing details 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
Bore sets the force: at 0.5 MPa this 20 mm double-acting cylinder gives 157.1 N push and 131.9 N pull, so step up to bore 25 (245.4 N push) if you need more. Choose MD if rod rotation is acceptable, or MK if the rod must not rotate; this MDJ is double acting with a 10, 20 or 30 mm adjustable range on top of the set stroke. Strokes for bore 20 run up to 60 mm, and the short covers mean an over-long stroke is best avoided. The trailing S means the magnet is included for switch sensing; PT or G thread is the other choice. Side-load ratings come from the datasheet, so route that question to us.
Applications
Adjustable clamp position
Fix the cylinder to the side of a small-parts clamp fixture and use the 10 mm adjustable range to dial in the clamping point, with the magnet confirming full clench via a switch slot.
Jig part presence check
Mount the cylinder from the top or bottom of an assembly jig to probe or seat parts, sensing the retracted position with the built-in magnet for a simple interlock signal.
Lateral part push-off
Bolt the body sideways to a conveyor frame to push parts off the belt into a bin, mounting units side by side along the line and tuning the push distance with the adjustable stroke.
FAQ
How does MDJ20X30-10S differ from the plain MD20X30?
Both are 20 mm bore, 30 mm stroke double-acting multi-mount cylinders, but MDJ is the adjustable-stroke variant: the -10 adds a 10 mm adjustable range on top of the set stroke, so the effective stroke can be set from 30 mm to 40 mm. The trailing S also means this SKU includes the magnet, and the thread is PT.
Is a long stroke a problem on this compact cylinder?
Yes, it can be. The multi-mount body has short covers, so a stroke that is long relative to the compact body is best avoided for stability. Bore 20 strokes run up to 60 mm in the table, and any side-load the application introduces must be checked against the datasheet, so confirm the details with us.
