Airtac MDJ Adjustable Cylinder MDJ25X40-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ25X40-10S 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 MDJ25X40-10S
The AirTAC MDJ series is a compact multi-mount cylinder whose square body fixes from six directions: front, back, left, right, top and bottom. Units mount side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubricant. This MDJ25X40-10S is double acting with a 25 mm bore, a 40 mm stroke and an extra 10 mm of adjustable stroke, giving a theoretical push thrust of 245.4 N at 0.5 MPa. Cushioning is by bumper. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), from -20 to 70 C.
This is a genuine AirTAC part. The MD family is the standard multi-mount cylinder, while the MK family adds a no-rotating plate for jobs where the rod must not turn. The trailing S in this SKU means it is supplied with a magnet for switch-based position detection. We are glad to 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.
How to choose
Choose the 25 mm bore when you need roughly 245.4 N of push thrust at 0.5 MPa (206.2 N on the pull side). MDJ is the adjustable-stroke, double-acting member of the standard MD family; pick MK instead if the rod must be prevented from rotating. The 40 mm base stroke sits within the 60 mm maximum for this bore in double acting, and the -10 suffix adds a further 10 mm of adjustment on top. Keep the stroke within reason, since the short cover limits over-long strokes, and route side-load questions to us. The trailing S means this SKU carries a magnet; port thread is PT as standard, with G available.
Applications
Indexing fixture on a rotary table
Locking each station of a rotary indexing table; the magnet lets a switch confirm the clamp is fully home before the table advances.
Gate on a sorting conveyor
Deflecting small parcels between lanes in a tight sortation layout, with the body fixed top and bottom and units side by side.
Small-parts clamp in pick-and-place
Gripping a light component against a nest during transfer, with position detection at both ends of the trimmed 40 mm stroke.
FAQ
What does the S at the end of MDJ25X40-10S mean?
The trailing S means this cylinder is supplied with a magnet, so magnetic switches seated in the body slots can signal rod position. The same model without the S is supplied without a magnet; the magnet is an option, not a fixed feature.
How much side load can the rod take?
A specific side-load figure is not published in the general listing, so please confirm side-load limits from the datasheet or ask us before loading the rod laterally. Overall dimensions also vary with stroke and come from the datasheet.
