Airtac MDJ Adjustable Cylinder MDJ6X20-10
The AirTAC Airtac MDJ Adjustable Cylinder MDJ6X20-10 is a genuine MD multi-mount cylinder (adjustable stroke), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 14.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ6X20-10
A compact multi-mount cylinder fixes from six directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space. This MDJ is the adjustable-stroke version of AirTAC's standard MD family: double acting, 6mm bore, 20mm main stroke plus a 10mm adjustable range, cushioned by a bumper. On filtered air at 0.5 MPa the 6mm bore provides a theoretical push thrust of 14.1 N, adequate for light clamping, positioning and small gate duty.
This is a genuine AirTAC part. The MD family is the standard type in which rod rotation is allowed; select the MK no-rotating family where rotation must be prevented. This SKU is supplied without a magnet, though switch slots run around the body for when a magnet-equipped variant is chosen. 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
Size by thrust first: at 0.5 MPa the 6mm bore yields 14.1 N theoretical push and 10.6 N pull, the smallest in the multi-mount range. Use MD when rod rotation is permissible and MK no-rotating when it is not. This MDJ is double acting with a 10mm adjustable range on top of the 20mm main stroke; adjustable ranges are offered in 10, 20 and 30mm. Double-acting bore 6 strokes reach 35mm, though short covers caution against stretching to the limit, so match the stroke to the job. Magnet is optional via the S suffix - absent here. PT thread is standard with G as an option; route side-load and dimension questions to us or the datasheet.
Applications
Height-adjustable ejection pins
The 20mm stroke plus 10mm adjustment covers varying part heights on eject or lift stations, with the 6mm bore's 14.1 N push at 0.5 MPa suiting lightweight plastic parts.
Small-parts clamping
Fixing from six directions lets the cylinder bolt directly into tight fixture corners, holding small components with double-acting force while the bumper cushions each clamp cycle.
Conveyor gate and diverter duty
The compact square body mounts along conveyor frames from any face and side by side where space is tight, swinging small gates or diverters with 20mm of travel plus fine adjustment.
FAQ
How does the adjustable range work on the MDJ6X20-10?
The MDJ double-acting cylinder has a 20mm main stroke and an extra 10mm adjustable stroke, so total travel can be set anywhere up to 30mm. Adjustable ranges are offered in 10, 20 or 30mm on MDJ and MKJ models; the 10mm version is what this SKU carries.
What should I check before fixing this cylinder into my machine?
The multi-mount body can be fixed from all six directions - front, back, left, right, top and bottom - and mounted side by side, but the covers are short, so do not pair the bore with an over-long stroke. Confirm overall dimensions for your stroke and any side-load figures from the datasheet before finalizing the design.
