Airtac MDJ Adjustable Cylinder MDJ25X5-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ25X5-10S is a genuine MD multi-mount cylinder (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 MDJ25X5-10S
The MDJ25X5-10S is an AirTAC multi-mount cylinder whose compact square body fixes from six directions - front, back, left, right, top and bottom - and installs side by side to save space. Double acting with a 25 mm bore, it produces 245.4 N of theoretical push force at 0.5 MPa, with a short 5 mm base stroke plus a 10 mm adjustable range for fine, repeatable moves. Cushioning is a bumper, magnetic-switch slots run around the body, and the guides hold high precision without added lubricant.
This is a genuine AirTAC part. The MD family is the standard multi-mount cylinder where the rod may rotate; the MK family is the no-rotating version when orientation must be held. The S suffix here means the magnet is supplied, so the switch slots can be used for position feedback out of the box. We can confirm overall 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.
How to choose
Size the bore to the thrust: a 25 mm double acting cylinder gives 245.4 N theoretical push at 0.5 MPa. Take MD if rod rotation is fine, MK if it is not. Acting choices run double, single-push, single-pull, double rod and adjustable-stroke; this MDJ unit is double acting with a 5 mm base stroke plus a 10 mm adjustable range - a good fit where the stroke is inherently short but setup adjustment matters. The bore 25 double acting stroke table goes up to 60 mm; the covers take up body length, so keep strokes short on compact fixtures and route side-load questions to us. The S suffix supplies the magnet - order the non-S code if you do not want it. Port is M5x0.8 with PT thread; G thread is available on request.
Applications
Pick-and-place ejection
Fix the cylinder through the top or side mounting faces to give a short 5 mm (plus 10 mm adjustable) push that releases small parts from a vacuum gripper nest, with magnet feedback confirming position.
Micro clamping with sensing
Cluster units side by side on an assembly fixture to clamp small components; the supplied magnet lets the PLC verify clamp and unclamp at each station.
Stopper height selection
Mount under a conveyor stopper blade to switch between two heights with a 5 mm lift, using the adjustable range to set blade travel exactly to the part size.
FAQ
What does the S mean and how do I decode MDJ25X5-10S?
Read it as: MDJ adjustable-stroke double acting family, 25 mm bore, 5 mm base stroke, 10 mm adjustable range, S = supplied with magnet, no trailing G = PT thread. If the magnet is not needed, the MDJ25X5-10 code is the same cylinder without it.
Is a 5 mm stroke enough, and how is it mounted?
The body fixes from six directions (front, back, left, right, top, bottom) so it drops into tight fixtures, and the 10 mm adjustable range covers setup variation beyond the 5 mm base stroke. Bear in mind the covers occupy body length, so very short strokes like this are exactly where multi-mount saves space; overall dimensions depend on stroke, so confirm them from the datasheet and ask us about side-load limits.
