Airtac MDJ Adjustable Cylinder MDJ16X40-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X40-10S 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 MDJ16X40-10S
The AirTAC MDJ16X40-10S is an adjustable-stroke multi-mount cylinder: a compact square-body, double-acting unit that fixes from six directions and mounts side by side to save space in dense machine layouts. Its 16 mm bore produces about 100.5 N of theoretical push force at 0.5 MPa over a 40 mm stroke with a 10 mm adjustable range for precise end-of-stroke setting, and the cushion is a bumper. The magnet is built in, so a switch seated in the slots around the body can signal end positions. Speed range is 30-500 mm/s, with high guide precision and no added lubricant needed.
This is a genuine AirTAC part in the MD standard series, where the rod may rotate unless externally guided; for rotation prevention, the MK family adds a built-in no-rotating plate. Medium is air filtered to 40 um, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and the temperature range is -20 to 70 C (0 to 150 C only with the optional high-temperature seal material). Overall dimensions and detailed sizing are per the datasheet, which we confirm 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 thrust point: about 100.5 N of theoretical push at 0.5 MPa with the pull side lower, so choose a 20 or 25 mm bore for heavier clamping. MD (this model) suits jobs where rod rotation is acceptable; MK is the choice when rotation must be prevented. Acting types run from double, single push (MSD/MSK) and single pull (MTD/MTK) to double rod (MDD/MKD) and adjustable stroke (MDJ/MKJ, which adds a 10 mm adjustable range to the 40 mm stroke here). Bore 16 strokes go up to 50 mm, and a short stroke relative to the cover is the stable pick because an over-long stroke reduces rigidity; treat side-load as a datasheet question to confirm with us. Magnet is ordered with the S suffix (as on this SKU), and thread is PT (default) or G.
Applications
Small-parts clamp
Banked side by side on a fixture plate, these 16 mm cylinders clamp small housings or terminals in place; the magnet and body slots give a clamped/released signal for the PLC without external sensing hardware.
Vertical lift-and-lower stopper
Fixed from the top or bottom face of the body, the cylinder raises and lowers a light stopper in a vertical feed chute, and the adjustable range trims the lift height so parts stop level at the pick position.
Gate hold-back on an assembly line
The bumper cushion takes the shock as the cylinder holds back or releases parts at a manual work gate, and side-by-side mounting keeps the mechanism within a narrow pitch on crowded line tooling.
FAQ
How much force does the MDJ16X40-10S produce, and what does the S add?
The 16 mm bore gives about 100.5 N of theoretical push force at 0.5 MPa, with the pull side somewhat lower, so size the bore to the load. The trailing S means the cylinder is built with a magnet, so a switch placed in the slots around the body can report stroke-end positions; the same model without the S (MDJ16X40-10) is supplied magnet-free.
Can I shorten the stroke to suit my fixture?
Yes. As an MDJ adjustable-stroke cylinder it adds a 10 mm adjustable range on top of the 40 mm stroke, so the effective end position can be trimmed during setup. Do keep the stroke short relative to the cover on a compact body, because an over-long stroke costs stability; exact dimensions and allowable side-load come from the datasheet, so confirm them with us.
