Airtac MDJ Adjustable Cylinder MDJ25X50-50S
The AirTAC MDJ Adjustable Cylinder MDJ25X50-50S is a genuine MD multi-mount cylinder (double rod, adjustable stroke), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 245.4 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ25X50-50S
The MDJ25X50-50S is a 25 mm bore, 50 mm stroke adjustable-stroke multi-mount cylinder from AirTAC's MD family, double acting, with a 50 mm adjustable range on top of the fixed stroke. The square body fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side to save space, with magnetic-switch slots around the body. At 0.5 MPa it pushes with a theoretical 245.4 N, and the cushion is a bumper.
This is a genuine AirTAC part. MD-family cylinders are the standard multi-mount design; the MK family is the no-rotating version. The trailing S in this model code means the SKU includes a magnet for position detection. Overall dimensions depend on the stroke, so we confirm sizing and dimensions 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 MD (rotation allowed) or MK (rotation prevented); this model is MD, double acting. The 50 mm stroke sits within the bore-25 table (up to 60 mm), with a 50 mm adjustable range on top. Pick the S suffix for a magnet, and PT or G thread - this SKU is PT. The compact body keeps covers short, so avoid an over-long stroke for the space you have; for side-load capability, check with us.
Applications
Pick-and-place of small parts
Mounted from the top or side of a compact transfer station, the cylinder extends a gripper over a 50 mm travel, with the adjustable range letting technicians trim the reach to the part position without changing the body.
Product stopper on a conveyor line
Fixed to the conveyor frame from any of 6 directions, the cylinder raises or lowers a stopper blade to hold cartons at a workstation, with the adjustable stroke fine-tuning the stopping position.
FAQ
What does the model code MDJ25X50-50S decode to?
MDJ is the adjustable-stroke variant of AirTAC's standard MD multi-mount family, 25 is the bore in mm, 50 after the X is the stroke, the -50 is the adjustable range on top of the stroke, and the trailing S means this SKU includes a magnet. No trailing G means the ports are PT thread, M5x0.8 on this bore.
How many ways can I mount this cylinder?
The square body can be fixed from 6 directions - front, back, left, right, top and bottom - and cylinders can sit side by side to save space. Keep the stroke proportionate to the compact body, and confirm side-load capability and exact dimensions from the datasheet with us before finalising the fixture.
