The AirTAC Airtac MDJ Adjustable Cylinder MDJ10X25-30S is a genuine MD multi-mount cylinder (adjustable stroke), 10 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 39.3 N of push force at 0.5 MPa. A bumper cushions the impact.
The MDJ10X25-30S is an AirTAC MD-series adjustable-stroke multi-mount cylinder: a compact square-body air cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and installed side by side with other cylinders to save space. Switch slots around the body accept magnetic switches, guide precision is high, and no added lubricant is needed. This double-acting model combines a 10 mm bore, 25 mm stroke and 30 mm adjustable range, pushing with a theoretical 39.3 N at 0.5 MPa (33.0 N on the pull side), well matched to light clamping and repeat positioning, with a bumper providing the cushioning.
This is a genuine AirTAC part. Within the multi-mount range, MD is the standard family where the rod may rotate, while MK adds a no-rotating plate when rod orientation must stay fixed. The trailing S shows this SKU includes the magnet, and the thread is PT. Since dimensions change with stroke, we 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.
Size the bore for thrust: 10 mm bore gives 39.3 N push and 33.0 N pull at 0.5 MPa double acting, so choose a larger bore for higher force. MD allows rod rotation; MK prevents it. Acting choices are double acting, single push, single pull, double rod and adjustable-stroke, and this MDJ is double acting with 25 mm of stroke, inside the 35 mm cap for bore 10, plus a 30 mm adjustable range. The trailing S means the magnet is included, enabling switch feedback; omit the S for a magnet-free build. Thread is PT standard, G optional. Keep the stroke short relative to the cover, and confirm side-load capacity with us.
The built-in magnet supports position sensing in compact pick-and-place heads, where 6-direction fixing lets the cylinder fit wherever the gripper layout demands.
Bolted side by side, multiple 10 mm cylinders clamp several small features in one tight fixture block, with the 30 mm adjustable range suiting different part heights.
Magnet-based switching verifies each advance in a light indexing fixture, and the bumper cushions the motion cycle after cycle on compact rotary tables.
MDJ is the standard multi-mount family, so the rod can rotate under side influence; MKJ adds a no-rotating plate and fixed rod when the rod orientation must be held. Both are double acting with the same 10 mm bore output range, so pick MKJ only when rotation must be prevented.
Yes. The 30 mm adjustable range sits on top of the 25 mm stroke, letting one cylinder serve several product heights in a fixture. Keep total travel within the bore 10 limit and avoid over-long strokes on the short cover; stroke-specific dimensions and side-load figures come from the datasheet.
