Airtac MDJ Adjustable Cylinder MDJ16X25-30
The AirTAC Airtac MDJ Adjustable Cylinder MDJ16X25-30 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 MDJ16X25-30
The MDJ16X25-30 is an AirTAC adjustable-stroke multi-mount cylinder with a 16 mm bore, a 25 mm base stroke and a 30 mm adjustable range. Its compact 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 and high guide precision that needs no added lubricant. As a double-acting cylinder it gives a theoretical push force of 100.5 N at 0.5 MPa (86.4 N on the pull side), runs at 30-500 mm/s and cushions with a bumper. It uses air filtered to 40 um, takes proof pressure of 1.5 MPa (215 psi) and operates from -20 to 70 C.
This is a genuine AirTAC part in the MD family, the standard version where rod rotation is allowed - choose the MK family when the rod must not rotate. The SKU ends without an S, so this unit is supplied without a magnet; trailing-S variants add one. The port is M5x0.8 with PT thread as the default (G optional). Overall dimensions vary with stroke, so confirm exact dimensions and sizing from the datasheet - we can supply it 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 bore for the force you need: at 0.5 MPa this 16 mm bore delivers 100.5 N theoretical push (86.4 N pull) in double acting. MDJ is the adjustable-stroke variant of the standard MD family, where rotation is allowed; pick the MKJ no-rotating version if the rod must stay fixed in orientation. Acting type is double here - single-acting push (MSD) and pull (MTD), double rod (MDD) are separate variants. The 25 mm base stroke sits within the bore-16 table (up to 50 mm), plus a 30 mm adjustable range; remember the short cover means an over-long stroke should be avoided, so check long-travel picks with us. Side-load capability is not stated here - route it to us. Magnet is absent on this SKU; add the S suffix if you need one, and select PT or G thread.
Applications
Adjustable small-parts clamp
Clamping small housings or brackets where the grip point changes between setups - the 30 mm adjustable range lets technicians trim the 25 mm stroke without swapping the cylinder, using the 16 mm bore's 100.5 N push to hold the part.
Conveyor gate and stopper
Extend into the product flow to divert or stop small parcels and components. The multi-mount body fixes from 6 directions, so it bolts onto the side, top or bottom of the conveyor frame in the same footprint.
Pick-and-place Z-stroke
Provide the short vertical press or release stroke in a compact pick-and-place head, where side-by-side mounting of multiple 16 mm cylinders saves panel space in tight automation cells.
FAQ
What does the -30 in MDJ16X25-30 mean?
It is the adjustable-stroke suffix: the cylinder has a 25 mm base stroke plus a 30 mm adjustment range, and only MDJ/MKJ variants carry this extra figure. A trailing S after it would indicate a built-in magnet; this SKU has no S, so it is supplied without a magnet.
How does 6-direction mounting help in a tight machine, and where do I get exact dimensions?
The square body lets you bolt the cylinder from the front, back, left, right, top or bottom and place units side by side, so the same bore fits wherever there is a flat face. Overall dimensions change with stroke, so confirm them from the datasheet - we can provide it on request.
