The AirTAC Airtac MDJ Adjustable Cylinder MDJ20X20-10 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.
The AirTAC MDJ20X20-10 is an adjustable-stroke multi-mount cylinder with a compact square body 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. With a 20 mm bore, 20 mm base stroke and an additional 10 mm adjustable range, it delivers double-acting push force of about 157.1 N at 0.5 MPa, and its cushion is a bumper for end-of-stroke deceleration.
This is a genuine AirTAC part in the MD family, the standard multi-mount series where the piston rod is free to rotate; the MK family is the separate no-rotating version. As the SKU shows, this model is supplied without a magnet. Dimensions and sizing details for your layout can be confirmed 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.
Choose the 20 mm bore when you need around 157.1 N of push force at 0.5 MPa on the double-acting push side. MD means the rod may rotate; select MK if rotation must be prevented. The MDJ adjustable-stroke variant gives a 20 mm working stroke plus a 10 mm adjustable range on top, on top of the bore 20 standard stroke table that goes up to 60 mm. This SKU carries no magnet (the trailing S option adds one) and a PT thread; G is available as an alternative. Keep the stroke modest - the short cover limits how long a stroke the body can accept - and confirm allowable side-load with us before applying it.
Bolted through the top or side of a fixture, the cylinder clamps small parts in place, with the 10 mm adjustable range tuned to grip different part heights.
Side-by-side mounting lets several MDJ cylinders set stop and locating positions on a jig, each fixed from whichever of the 6 body faces suits the fixture.
Mounted under a conveyor line, the cylinder raises or swings a gate or stopper, with the bumper cushioning the part at the end of each 20 mm stroke.
MDJ is the adjustable-stroke multi-mount cylinder, 20 is the bore in mm, the first 20 is the working stroke, and -10 adds a 10 mm adjustable range on top of that stroke. The variant with an S suffix (MDJ20X20-10S) is the same cylinder with a magnet; this SKU has no magnet.
Yes. The square body is designed to be fixed from 6 directions - front, back, left, right, top and bottom - so it fits compact, side-by-side layouts. For exact mounting dimensions and allowable side-load figures, confirm from the datasheet or ask us.
