About the Airtac MDJ Adjustable Cylinder MDJ20X20-20
The AirTAC MDJ20X20-20 is an adjustable-stroke multi-mount cylinder with a square body that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side with other cylinders to save panel space. Its 20 mm bore provides double-acting push force of about 157.1 N at 0.5 MPa over a 20 mm stroke plus a 20 mm adjustable range, with a bumper as the cushion.
This is a genuine AirTAC part from the MD family, the standard multi-mount series where the rod is free to rotate; choose the MK family when rotation must be prevented. As the SKU shows, this model is supplied without a magnet. Dimensions and sizing 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.
How to choose
The 20 mm bore suits jobs needing about 157.1 N of push at 0.5 MPa, double acting. MD allows rod rotation; pick MK if that must be stopped. This MDJ model pairs a 20 mm working stroke with a 20 mm adjustable range - the larger of the two adjustable options (10/20 mm) - and sits within the bore 20 standard stroke table of up to 60 mm. This SKU has no magnet (add the S suffix for one) and a PT thread, with G available. Respect the short-cover limit on stroke length, and route any side-load question to us before finalising the design.
Applications
Small-parts clamping
Fixed from the side or bottom of a fixture, the cylinder clamps small parts, with the 20 mm adjustable range covering taller or varied part stacks.
Indexing fixture stops
Side-by-side mounting lets the cylinder act as an indexing stop on a rotary or linear table, adjusted to each index position within its 20 mm range.
Gate and stopper actuation
Mounted beneath a conveyor, the cylinder extends a stopper or swings a gate, with the bumper taking the impact at the end of each cycle.
FAQ
How is MDJ20X20-20 different from MDJ20X20-10?
Both are 20 mm bore adjustable-stroke multi-mount cylinders with a 20 mm working stroke; the difference is the adjustable range - 20 mm on this model versus 10 mm on the -10. Both are double acting with the same 157.1 N push force at 0.5 MPa.
Which ways can I mount this cylinder from?
The square body is designed to be fixed from 6 directions: front, back, left, right, top and bottom. That flexibility, plus the ability to mount cylinders side by side, is what saves space in tight fixtures. Exact mounting dimensions and side-load limits should be confirmed from the datasheet.
