Airtac MD Multi-Position Clamping Cylinder MD25X30S
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD25X30S 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 MD25X30S
The MD25X30S is a genuine AirTAC MD multi-mount cylinder with a compact square body that fixes from 6 directions - front, back, left, right, top and bottom - and mounts side by side with other units to save space on dense machine panels. This double acting model combines a 25 mm bore with a 30 mm stroke and a theoretical push thrust of 245.4 N at 0.5 MPa, well matched to short-travel clamping, stopping and positioning. Cushioning is a bumper. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), from -20 to 70 C (up to 150 C only with the optional high-temperature seal material), at 30-500 mm/s.
This is a genuine AirTAC part. The MD family is the standard multi-mount cylinder; the MK family is the no-rotating equivalent if your application requires the rod to stay rotationally fixed. The trailing S in MD25X30S means this SKU ships with the magnet fitted for magnetic-switch detection. Port is M5x0.8 with PT thread on this bore. We confirm exact 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
Match the bore to your thrust requirement: at 0.5 MPa this 25 mm bore gives a theoretical 245.4 N on the push side and 206.2 N on the pull side. Use MD where some rod rotation is tolerable and MK where it is not. Acting options are double acting (this unit), single acting push (MSD), single acting pull (MTD), double rod (MDD) and adjustable stroke (MDJ, adding 10/20/30 mm of adjustability). The 25 mm bore accepts double acting strokes up to 60 mm, but the short covers are designed for compact strokes - resist over-long stroke selections on this body. This SKU carries the magnet (S); omit the S for a non-magnetic unit. Thread is PT standard, G optional. Route side-load questions to the datasheet or to us.
Applications
Small-parts clamp on an assembly fixture
The 245.4 N push at 0.5 MPa over a 30 mm stroke holds small housings or brackets steady during screwdriving or welding, with the magnet confirming the clamp is closed via a switch in the body slot.
Conveyor stopper gate
Fix the body from above or below the conveyor frame to raise and lower a stopper blade for singling parts on the line, using the 6-way mounting to fit the tight under-belt space.
Vertical part eject
Mount the cylinder with its rod pointing down in a nest to eject or release a finished small part from its locator, with side-by-side mounting supporting multi-station layouts.
FAQ
How do I choose between MD25X30S and the MK equivalent?
Choose MD25X30S if your application tolerates some rotation of the piston rod; choose the MK family if the rod must be prevented from turning, as MK adds a no-rotating plate, bushing and fixed rod. Both share the same compact 6-direction multi-mount body and mounting pitch.
Where do I find the installed length and side-load limits for this cylinder?
Overall dimensions vary with the stroke, and allowable side load is a datasheet figure rather than a listed value here. Contact us and we will confirm the exact dimensional drawing and side-load guidance for the MD25X30S before you finalize your fixture design.
