Airtac MDJ Adjustable Cylinder MDJ16X15-20S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X15-20S 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 MDJ16X15-20S
The MDJ16X15-20S is an adjustable-stroke model in AirTAC's multi-mount cylinder series, a compact square-body air cylinder 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. This double-acting bore 16 unit has a 15 mm base stroke plus a 20 mm adjustable range, so the effective stroke can be trimmed to the exact length your station needs. At 0.5 MPa it delivers a theoretical push force of 100.5 N, enough for light clamping, positioning and stopper duties, and cushioning is provided by a bumper.
This is a genuine AirTAC part in the standard MD family, where the rod is free to rotate unless your tooling prevents it - if the load must not turn, choose the no-rotating MK family instead. The trailing S in the code means this SKU includes the position-magnet option for switch detection. Magnetic-switch slots are machined around the body, and we can 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
Bore 16 is the right choice when your load needs roughly 100.5 N of theoretical push at 0.5 MPa; step up to bore 20 (157.1 N) or down to bore 10 (39.3 N) if your force requirement differs. This is the MD standard body, which allows rod rotation - pick the MK no-rotating family if the load must stay orientation-fixed. Acting is double acting (pressure extends and retracts); single-push, single-pull and double-rod versions exist elsewhere in the range.
The 15 mm stroke sits well inside the bore 16 double-acting table limit of 50 mm, and the MDJ suffix adds a 10/20/30 mm adjustable range - this SKU carries the 20 mm range. The trailing S means the magnet is fitted; unmarked SKUs omit it. Ports are M5x0.8, with PT thread standard and G available as the alternative. Keep strokes short on this compact body - an over-long stroke on a short cover is the usual mis-selection, and side-load capacity is a datasheet figure, so route that question to us.
Applications
Small-parts clamping
Clamp small machined or moulded parts in a compact fixture where the 6-direction fixing lets the cylinder bolt directly into tight fixture walls and the 100.5 N push at 0.5 MPa holds the part.
Jig positioning on assembly benches
Position workpieces in drill or press jigs using the adjustable 20 mm range to dial the stop position in, with cylinders mounted side by side on multi-station jigs to save bench space.
Indexing on rotary tables
Act as an indexing or dwell stopper on small rotary indexing tables, where the magnet-equipped body drives a reed or hall sensor and the bumper cushions the stop.
FAQ
What does the code MDJ16X15-20S actually specify?
MDJ is the adjustable-stroke version of the standard MD double-acting family, 16 is the bore in mm, 15 is the base stroke in mm, -20 is the 20 mm adjustable range, the trailing S means the magnet is included, and no G suffix means PT ports. The same body without the S omits the magnet.
Can I mount this cylinder from any face of its body?
Yes - the multi-mount square body fixes from 6 directions (front, back, left, right, top and bottom) and cylinders mount side by side to save space. Overall dimensions change with stroke, so confirm the exact envelope from the datasheet before laying out your fixture.
