The AirTAC Airtac MDJ Adjustable Cylinder MDJ10X15-20S 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.
A multi-mount cylinder is a compact square-body air cylinder that fixes from six directions - front, back, left, right, top and bottom - and mounts side by side to save space. This MDJ10X15-20S is the adjustable-stroke member of the MD family: double acting, 10 mm bore, 15 mm basic stroke plus a wide 20 mm adjustment range for setups that change. At 0.5 MPa it gives a theoretical push force of 39.3 N (slightly less on the pull side), cushioning is a bumper, magnetic-switch slots are machined around the body, and it runs at 30-500 mm/s on air filtered to 40 um.
This is a genuine AirTAC part. The MD family is the standard multi-mount design in which the rod is free to rotate; only the MK family adds a no-rotating plate. The trailing S means this model carries a magnet for position sensing. Overall dimensions for your stroke and sizing checks can be confirmed from the AirTAC 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.
Pick MD (rotation allowed) over MK (no-rotating plate) when the rod may turn. This MDJ is double acting with an adjustable stroke: 15 mm basic plus a 20 mm adjustment range, comfortably within the 35 mm stroke table for a 10 mm bore, and the short covers guard against over-long strokes. The trailing S orders it with a magnet; the thread is PT as standard with G optional. Operating range is 0.15-1.0 MPa (22-145 psi); confirm side-load limits from the datasheet or ask us.
Cylinder bodies bolted in a row beneath a chute eject small parts in sequence; the 20 mm adjustment range lets you tune the 15 mm push travel as the tooling changes.
Fixed from the front of a machining fixture, the double-acting rod advances to a trimmed position within its 15 mm plus 20 mm range to seat parts before processing.
Side-mounted next to a diverting gate on a conveyor, the cylinder strokes the gate across the lane, with the bumper absorbing the motion at each end of travel.
The -20 suffix adds a 20 mm adjustment range on top of the 15 mm basic stroke, so one cylinder can be re-tuned in service as the stroke requirement changes. It is still double acting with a 10 mm bore, 39.3 N theoretical push at 0.5 MPa, and the trailing S means it includes the magnet.
For a 10 mm double-acting multi-mount cylinder the stroke table tops out at 35 mm; keeping the stroke short preserves the compact covers, so avoid over-long strokes. This model carries 15 mm basic plus 20 mm adjustment, and exact body dimensions come from the AirTAC datasheet - we can confirm them for you.
