Airtac MDJ Adjustable Cylinder MDJ6X20-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ6X20-10S 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 MDJ6X20-10S
The MDJ6X20-10S is an AirTAC multi-mount cylinder with an adjustable stroke: a compact square-body pneumatic cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with other units to save space. This model is double acting with a 6 mm bore and a 20 mm base stroke, plus a 10 mm adjustable range on top of the base stroke - useful where the exact end position needs to be dialled in on the machine. At 0.5 MPa the bore gives a theoretical push force of about 14.1 N, and the cushion is a bumper.
This is a genuine AirTAC part in the standard MD family (the no-rotating equivalent is the MKJ). The trailing S in the code means this SKU is supplied with a magnet for position sensing. Exact dimensions depend on stroke, so we confirm sizing and dimensions 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
Bore 6 is the smallest option, with about 14.1 N theoretical push at 0.5 MPa - right for light clamping and small-part handling. Choose MD if rod rotation is acceptable, or MK (MKJ) if the rod must not rotate. This MDJ is double acting with an adjustable stroke: 20 mm base stroke plus a 10 mm adjustable range, which stays within the bore-6 double-acting stroke table (up to 35 mm). The trailing S means this SKU includes a magnet; the same code without S omits it. Port thread is PT as standard, with G available. The compact cover limits practical stroke, so avoid over-long strokes - ask us about side-load limits.
Applications
Small-parts clamp
The 6 mm bore and short 20 mm stroke suit light clamping of small components in fixtures, with the 10 mm adjustable range letting operators fine-tune clamp position. Six-way fixing lets the clamp be bolted in from whichever face the fixture allows.
Jig positioning stop
Mounted side by side on a jig body, these compact square cylinders act as adjustable positioning stops. The bumper cushion softens repeated contact, and the adjustable range covers slight part-size variations.
Feeder gate control
On parts-feeding chutes and small conveyors, the compact body fits where space is tight, switching between flow and stop positions. Mounting from 6 directions makes installation on narrow machine frames straightforward.
FAQ
What does the MDJ6X20-10S code actually specify?
MDJ is the AirTAC adjustable-stroke, double-acting multi-mount cylinder; 6 is the bore in mm; X20 is the 20 mm base stroke; -10 adds a 10 mm adjustable range on top of the base stroke; the trailing S means this SKU is supplied with a magnet; no trailing G means the standard PT port thread. The port on this bore is M5x0.8.
Can I mount this cylinder in any orientation?
Yes. The multi-mount body can be fixed from 6 directions - front, back, left, right, top and bottom - so it can be installed in any orientation and side by side with further cylinders to save space. Keep strokes within the bore-6 double-acting table (up to 35 mm), and confirm exact dimensions and side-load limits from the datasheet before designing the mount.
