Airtac MD Multi-Position Clamping Cylinder MD25X20H
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD25X20H 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 MD25X20H
A multi-mount cylinder is a compact square-body air cylinder that can be fixed from six directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space. This MD25X20H is the standard double acting MD variant with a 25 mm bore and a 20 mm stroke, giving a theoretical push force of 245.4 N at 0.5 MPa on air filtered to 40 um. Cushioning is a bumper, magnetic-switch slots run around the body, and guide precision is high without added lubricant.
This is a genuine AirTAC part. The H suffix on this SKU denotes the high-temperature seal option, extending service from the standard -20 to 70 C up to 0 to 150 C; confirm the exact seal detail from the datasheet. Like all MD variants it is not rotation-locked - for a rod that must not turn, use the MK no-rotating family. There is no magnet on this SKU (no trailing S), ports are PT thread (M5x0.8 on this bore), and we 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
Bore sets the force: this double acting 25 mm cylinder gives 245.4 N theoretical push at 0.5 MPa (206.2 N pull side) over 0.15-1.0 MPa (22-145 psi). Choose the H-suffixed build when ambient or radiated heat exceeds the standard -20 to 70 C range; without the high-temperature seals, stay at or below 70 C. MD allows rod rotation, MK prevents it; acting options include double, single push (MSD), single pull (MTD), double rod (MDD) and adjustable stroke (MDJ). The 20 mm stroke is well inside the 60 mm maximum for a double acting 25 mm bore, but the compact covers caution against over-long strokes - route side-load questions to us. No magnet on this SKU (S adds one); thread is PT with G available.
Applications
Clamping near a heated mold
Clamps or ejects small parts beside warm tooling where ambient heat rules out standard NBR seals; the H build's high-temperature seals allow service up to 150 C.
Vertical stopper under an oven line
Lifts a stopper pin to halt parts entering or leaving a heated process zone; the square body fixes top or bottom from six directions in cramped framing.
Compact eject in a hot-work cell
Ejects finished small castings or heat-treated parts from a nest using the 20 mm stroke and 245.4 N push at 0.5 MPa, with bodies mounted side by side to save panel space.
FAQ
What does the H mean in MD25X20H, and how hot can it run?
The H suffix indicates the high-temperature seal option, which extends operation from the standard -20 to 70 C up to 0 to 150 C. Confirm the exact seal material and any application limits from the datasheet before ordering.
Can I lengthen the stroke beyond 20 mm on this cylinder?
A double acting 25 mm bore can be ordered up to 60 mm of stroke, but this compact series uses short covers, so avoid stretching the stroke beyond what the application needs. Exact dimensions and side-load limits should be confirmed from the datasheet.
