Airtac MD Multi-Position Clamping Cylinder MD25X20S
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD25X20S 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 MD25X20S
The MD25X20S is a compact multi-mount cylinder: a square-bodied unit that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side so several cylinders occupy a minimum of panel space. This is the double-acting MD version with a 25 mm bore and 20 mm stroke, delivering a theoretical push force of 245.4 N at 0.5 MPa with 0.15-1.0 MPa (22-145 psi) working pressure on filtered air. Cushioning at each end of the stroke is by bumper, and magnetic-switch slots around the body let you fit switches flush against the cylinder.
This is a genuine AirTAC part in the standard MD family, where rod rotation is not prevented. The trailing S in the code means this SKU is supplied with a magnet for position sensing. Port thread is PT as coded, with an M5x0.8 port on this bore. We confirm dimensions, exact rod material and sizing details 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 bore by the thrust you need: at 0.5 MPa this 25 mm double-acting bore gives 245.4 N on the push side (the pull side is lower), stepping down to 157.1 N on a 20 mm bore or up to 402.1 N on 32 mm. Pick MD if a little rod rotation is acceptable in your fixture; pick MK if the rod must not rotate. Acting types run from double acting (MD) through single-acting push (MSD) and pull (MTD), double rod (MDD) and adjustable stroke (MDJ).
The 20 mm stroke sits comfortably within this bore's table, which runs up to 60 mm for double-acting cylinders - keep the stroke short, because the covers stay compact only within the catalogue range. This SKU carries the magnet option (S) and a PT thread; a G thread version is available. If your application applies side load to the rod, confirm the allowable value with us before ordering.
Applications
Small-parts clamping
Bolt several MD25X20S units side by side along a fixture and clamp multiple small components in one press cycle, using the 6-way fixing to orient each cylinder as the jig requires.
Jig positioning
Use the bumper-cushioned 20 mm stroke to seat workpieces against a hard stop in a drilling or assembly jig, with the magnet signaling home position to the controller.
Indexing fixtures
Mount cylinders face-to-face or top-and-bottom on a rotary indexing table using the six-direction fixings, keeping pitch minimal on crowded fixture plates.
FAQ
How much force does the MD25X20S produce, and what does the S in the code mean?
At 0.5 MPa this 25 mm double-acting cylinder gives a theoretical push force of 245.4 N (pull side is lower). The trailing S means this SKU is supplied with a magnet for position sensing; versions without the S carry no magnet. Working pressure is 0.15-1.0 MPa (22-145 psi).
How do I fix a multi-mount cylinder, and can I use a longer stroke?
The square body can be fixed from six directions - front, back, left, right, top and bottom - and cylinders can sit side by side to save space. Keep the stroke within the catalogue table (up to 60 mm for this bore, double acting): the compact covers are designed for short strokes, and an over-long stroke loses the space benefit. Side-load limits and exact dimensions come from the datasheet - confirm with us.
