Airtac MDJ Adjustable Cylinder MDJ16X50-50S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X50-50S 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 MDJ16X50-50S
The MDJ16X50-50S is an AirTAC MD-family multi-mount cylinder: a compact square-body, double-acting actuator that fixes from six directions (front, back, left, right, top and bottom) and mounts side by side with other cylinders to save space. The 16mm bore gives about 100.5 N of theoretical push force at 0.5 MPa, with a 50mm stroke plus the adjustable range shown in the code, an S suffix indicating a built-in magnet, and a bumper as the cushion. That combination fits adjustable positioning, clamping and pushing duties where the stroke must be set on the machine. As a genuine AirTAC part, this is the standard MD variant where rod rotation is allowed; the MKJ series is the no-rotating equivalent. Operating range is 0.15-1.0 MPa (22-145 psi) on filtered air, and we confirm exact dimensions, adjustable-range limits and switch compatibility 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
Size the bore to the thrust: the 16mm bore delivers about 100.5 N of push at 0.5 MPa (the pull side is lower), so move up or down a bore if that does not match your load. The MDJ prefix gives you an adjustable stroke - base stroke after the X, adjustable range after the hyphen - which is useful when the final stroke is set during commissioning. MD allows rod rotation; choose MK if the rod must not turn. Acting type is double acting, air-driven both ways. The S means the magnet is included for magnetic-switch position sensing; omit the S if you do not need it. Thread is PT, with G available. Keep the stroke within the bore's table given the short multi-mount covers, and route side-load questions to us.
Applications
Adjustable ejector station
On a small assembly fixture, the adjustable stroke lets a technician tune the ejector travel so finished parts clear the nest without a full redesign, using the bumper to soften each stroke.
Indexing-position setting
Fixed from the top of a dial or linear indexing table, the cylinder advances a locking pin into each position, with the magnet confirming the engaged point before the cycle continues.
Compact slide extension
Mounted side by side in a tight machine base, the cylinder extends a small guide slide where space forbids a tie-rod body, pushing parts or carriers about 100.5 N at 0.5 MPa.
FAQ
How do I interpret the stroke figures in MDJ16X50-50S?
The value after the X is the base stroke (50mm) and the value after the hyphen is the adjustable range added on top, so the effective stroke can be set within that window during setup. Confirm the maximum total stroke for this bore from the datasheet before finalising your design.
Can the rod rotate on this cylinder?
No control of rotation is built in: this MD-family cylinder allows the rod to turn, so it suits pushing and clamping rather than anti-rotation duties. If the rod or toolplate must stay fixed angularly, choose the MKJ no-rotating variant instead, and ask us for datasheet dimensions and side-load figures.
