Airtac MD Multi-Position Clamping Cylinder MD25X80
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD25X80 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 MD25X80
The MD25X80 is an AirTAC MD-series multi-mount cylinder: a compact square-body, double-acting air cylinder that fixes from six directions (front, back, left, right, top and bottom) and mounts side by side to save space. Magnetic-switch slots run around the body, guide precision is high, and no added lubrication is needed. With a 25 mm bore and 80 mm stroke it gives a theoretical push thrust of 245.4 N at 0.5 MPa (the pull side is lower at 206.2 N), cushioned by a bumper, over a 30-500 mm/s speed range on air filtered to 40 um.
This is a genuine AirTAC part. The MD family is the standard version where the rod is allowed to turn; the MK family is the separate no-rotating version. As the SKU shows, this cylinder is supplied without a magnetic piston (the S-suffix code adds one). Operating pressure is 0.15-1.0 MPa (22-145 psi). Dimensions, weight and sizing details are confirmed 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 drives thrust: at 0.5 MPa this 25 mm bore delivers 245.4 N push (206.2 N pull) in double-acting form. Choose MD if the rod may rotate, MK if rotation must be prevented. Acting choices are double acting, single-acting push (MSD), single-acting pull (MTD), double rod (MDD) and adjustable-stroke (MDJ, which adds a 10/20/30 mm adjustable range). The standard bore-25 stroke table runs up to 60 mm, so this 80 mm stroke sits beyond the standard table; confirm availability and exact dimensions from the datasheet. The magnet is optional (S suffix) and the port thread is PT (default) or G. With a long stroke on a short-cover body, route any side-load requirement to us.
Applications
Clamping taller workpieces in a weld fixture
Fix the square body to the fixture from the clearest face and use the 245.4 N push at 0.5 MPa to hold taller assemblies in place, with the bumper damping the clamp stroke.
Part ejector on a pallet-handling station
Mount the cylinder side by side with its neighbours on a compact station and use the 80 mm stroke to push finished pallets or trays clear of a nest at the end of a cycle.
Lift-and-lower gate in a small lift station
Fix the body top or bottom under a narrow lift frame and use the 80 mm double-acting stroke to raise and lower a light gate, with switch slots in the body giving end-of-travel signals.
FAQ
How does the MD25X80 compare with the MK version of the same size?
The MD25X80 is a standard double-acting cylinder, so the rod may rotate under its own friction. If your load must not turn, choose the MK family no-rotating version, which adds a plate, bushing and fixed rod to stop rotation. Thrust for the same 25 mm bore double-acting MK cylinder is in the same class; confirm details with us.
What should I check before using an 80 mm stroke on this cylinder?
This stroke runs beyond the standard bore-25 table (up to 60 mm), so confirm availability and overall dimensions from the datasheet before designing it in. Long strokes on a short-cover body put more side load on the guides, so keep the load aligned or send us your side-load question.
