Airtac MTD Multi-position Locking Cylinder MTD25X20
The AirTAC Airtac MTD Multi-position Locking Cylinder MTD25X20 is a genuine MD multi-mount cylinder (single acting, pull type), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 144.4 N of pull force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MTD Multi-position Locking Cylinder MTD25X20
The AirTAC MD series multi-mount cylinder is a compact square-body actuator that fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side to save space. This MTD25X20 is a single-acting, pull-type cylinder: compressed air retracts the 25 mm bore rod over a 20 mm stroke and the internal spring returns it, useful where the resting position must be extended. Cushioning is a bumper, and magnetic-switch slots are machined around the body. Operating pressure is 0.2-1.0 MPa (28-145 psi) with a speed range of 50-500 mm/s.
This is a genuine AirTAC part in the MD (standard) family, so rod rotation is not prevented; for a no-rotating version choose the MK family. As the SKU shows, there is no trailing S, so this cylinder is supplied without the magnet, and the thread is PT. Pull-side force, dimensions and sizing for this bore and stroke 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
Single-acting versions in this series cover strokes up to 20 mm, so this 20 mm SKU sits at the top of the single-acting stroke table. Choose MD (standard) if rod rotation is acceptable and MK (no-rotating) if it must not turn; acting choices are double acting, single push, single pull, double rod and adjustable-stroke. As a pull type, output on the air side is lower than the push side, so we confirm the exact force figure from the datasheet. This SKU has no S suffix, so no magnet is fitted; thread is PT with G available on other SKUs. Keep strokes short, as the compact cover limits over-long strokes, and route any side-load question to us.
Applications
Small-parts clamp
The spring keeps the rod extended to hold small parts by default, and air pulls it clear for loading. The 20 mm stroke suits clamping levers and swing latches on compact fixtures.
Conveyor gate and stopper
Air pulls a stopper blade down to release products and the spring raises it back into the path. The 6-way fixing lets the body mount under or beside a low-profile conveyor.
Indexing plunger
Retract an indexing pin with air so a dial plate or pallet can advance, then let the spring re-engage the next station. Side-by-side mounting suits multi-station rotary tables.
FAQ
Does the MTD25X20 include a position-sensing magnet?
No. The SKU has no trailing S, so this cylinder is supplied without the magnet. If you need magnetic-switch sensing, choose an S-suffix SKU such as MTD25X20S; the switch slots around the body are present either way.
How far can the rod travel on a single-acting bore 25 cylinder?
Single-acting versions in this series are limited to strokes up to 20 mm, so this 20 mm SKU is at the maximum. The compact cover design restricts over-long strokes; for longer travel or higher force, move to a double-acting bore 25 model, and confirm figures from the datasheet.
