Airtac MD Multi-Position Clamping Cylinder MD25X20SH
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD25X20SH is a genuine MD multi-mount cylinder (double acting), 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 MD Multi-Position Clamping Cylinder MD25X20SH
The MD25X20SH is a compact multi-mount cylinder: a square-bodied unit you can fix from six directions - front, back, left, right, top and bottom - and mount side by side to save panel space. This double-acting MD version has a 25 mm bore and 20 mm stroke, giving a theoretical push force of 245.4 N at 0.5 MPa over a working range of 0.15-1.0 MPa (22-145 psi) on filtered air. Cushioning is by bumper at each end of the stroke, and magnetic-switch slots run around the body.
This is a genuine AirTAC part in the standard MD family, so rod rotation is not prevented. The trailing S means the SKU is supplied with a magnet, and the H points to the optional high-temperature seal material: the cylinder runs from -20 to 70 C as standard, and the high-temperature seals extend the range to 0-150 C. Confirm the exact seal specification and dimensions 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 by thrust: at 0.5 MPa this 25 mm double-acting bore delivers 245.4 N on the push side, between the 157.1 N of a 20 mm bore and the 402.1 N of a 32 mm bore. Stay with the MD family when rod rotation is acceptable; choose the no-rotating MK family when the rod or tool plate must hold orientation. Acting choices are double acting, single-acting push or pull, double rod, or adjustable stroke.
The 20 mm stroke is well inside this bore's double-acting table, which runs to 60 mm - short strokes keep the covers compact, so avoid specifying more travel than the job needs. This SKU includes the magnet (S) and a PT thread, with G thread available as the alternative. If your fixture loads the rod sideways, confirm the allowable side load with us rather than assuming a figure.
Applications
Hot-process part clamping
With the high-temperature seal option, use MD25X20SH cylinders side by side to clamp warm mouldings or freshly machined parts in test and finishing fixtures.
Compact press station
Use the 245.4 N push at 0.5 MPa for light pressing and staking tasks on a densely packed multi-spindle bench, fixing each cylinder from whichever face suits the tooling.
Gate stopper on small conveyors
Mount the cylinder under or beside a conveyor line using the six-direction fixings to extend a stopper that gates parts at a station, with the magnet confirming the stopper is up.
FAQ
What does the H in MD25X20SH change, and what temperature can it handle?
The H indicates the optional high-temperature seal material. Standard MD cylinders operate from -20 to 70 C; with the high-temperature seals the range extends to 0-150 C. The rest of the code stays the same: 25 mm bore, 20 mm stroke, double acting, with magnet (S) and PT thread. Confirm the seal details from the datasheet.
Why should I keep the stroke short on this cylinder?
The multi-mount body stays compact because the covers are short, so strokes are limited by the catalogue table - up to 60 mm for this 25 mm bore in double-acting form. The 20 mm stroke here suits tight fixtures and side-by-side mounting. For exact dimensions and allowable side load at your stroke, confirm from the datasheet with us.
