Airtac MD Multi-Position Clamping Cylinder MD25X50S
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD25X50S 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 MD25X50S
The MD25X50S is an AirTAC MD-series multi-mount cylinder, a compact square-body actuator that fixes from 6 directions (front, back, left, right, top and bottom) and can be mounted side by side to save space. The 25 mm bore and 50 mm stroke in double acting configuration give a theoretical push force of 245.4 N at 0.5 MPa, suited to clamping, stopping and positioning duties in tight machine layouts. End-of-stroke cushioning is a bumper, keeping the design simple and serviceable.
This is a genuine AirTAC part. The MD family is the standard version; if your application needs the rod prevented from turning, look at the MK no-rotating family instead. The trailing S in this SKU means a magnet is fitted, so piston-position sensing is possible in the switch slots around the body. Ports are M5x0.8 with PT thread. We confirm dimensions, weights 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
Bore sets the force: at 0.5 MPa this 25 mm bore gives 245.4 N theoretical push in double acting use. Pick MD if rod rotation is allowed, or MK if it must be prevented. This model is double acting over 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a 50 mm stroke inside the bore 25 table (up to 60 mm). The trailing S means the magnet is included on this SKU, enabling position sensing; the non-magnet version is MD25X50. Thread is PT, with G available (MD25X50SH). The short covers caution against over-long strokes, and side-load ratings should be confirmed from the datasheet.
Applications
Fixture clamping with sensing
Fix the cylinder through the top or side of a fixture and clamp parts with 245.4 N at 0.5 MPa, using the fitted magnet in the body slots to signal a completed clamp.
Part stopper on a line
Bolt the body to the side of a conveyor or chute and extend a stopper over 50 mm to hold small parts; the magnet output confirms the stop is up before the next cycle.
Indexing fixture push
Mount units side by side in an indexing fixture to push workpieces into position each cycle, with the 6-way fixing letting the body fit flush against the jig wall.
FAQ
Is the magnet on the MD25X50S standard or optional?
The magnet is optional on MD-series cylinders and this SKU includes it, shown by the trailing S in the code. The MD25X50 without the S is supplied without a magnet. Either way, the switch slots around the body are part of the multi-mount design, and specific sensor part numbers should be confirmed from the catalogue.
How much force does this cylinder produce?
At 0.5 MPa this 25 mm bore double acting cylinder gives a theoretical push force of 245.4 N. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s. Exact dimensions and side-load limits vary with stroke, so confirm them from the datasheet.
