Airtac MDJ Adjustable Cylinder MDJ16X40-20
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X40-20 is a genuine MD multi-mount cylinder (adjustable stroke), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 100.5 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ16X40-20
The AirTAC MDJ16X40-20 is an adjustable-stroke multi-mount cylinder: a compact square-body pneumatic cylinder that can be fixed from six directions (front, back, left, right, top and bottom) and mounted side by side with neighbouring units to save panel space. This version has a 16 mm bore and 40 mm base stroke with an extra 20 mm adjustable range, double acting for powered strokes in both directions, delivering about 100.5 N of theoretical push force at 0.5 MPa. Cushioning is by bumper, so end-of-stroke impact is absorbed without an air cushion circuit.
This is a genuine AirTAC part from the MD family, the standard multi-mount series where the rod is free to rotate unless your tooling prevents it (the MK family adds a no-rotating plate instead). This SKU is supplied without a magnet; choose an S-suffix code if you need positional sensing in the body slots. Dimensions and sizing are per stroke - we confirm exact figures 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
Choose the 16 mm bore when your application needs roughly 100.5 N of push at 0.5 MPa; step up or down a bore if the load differs. MD is the standard series where rod rotation is allowed; pick MK if the rod must not turn. This code is double acting with an adjustable stroke: 40 mm base stroke plus a 20 mm adjustable range, within the bore-16 maximum of 50 mm, and the short cover means very long strokes should be avoided. The code has no S suffix, so it is without a magnet (add S for magnetic-switch readiness). Port thread is PT by default; G is available - route side-load questions to us.
Applications
Small-parts clamping
Bolted through any of six faces, the compact body clamps small parts in tight fixture nests, with the 20 mm adjustable range absorbing fixture height variation.
Pick-and-place gating
Side-by-side mounting lets several cylinders share one manifold plate to extend and retract product stops on a pick-and-place cell without extra brackets.
Jig positioning
The adjustable stroke lets a jig setter trim the press position of a locating pin to suit different workpiece batches without changing cylinders.
FAQ
What does the -20 in MDJ16X40-20 mean?
It is the adjustable stroke range in mm. The cylinder has a 40 mm base stroke plus a 20 mm adjustable range, so the effective stroke can be trimmed within that window. MDJ codes with -10 or -30 give 10 mm or 30 mm of adjustment instead.
How many ways can I mount this cylinder?
The square body fixes from six directions - front, back, left, right, top and bottom - and units mount side by side to save space. Exact overall dimensions depend on the stroke, so confirm them from the datasheet, and contact us about allowable side-load for your layout.
