Airtac MTD Multi-position Locking Cylinder MTD25X20S
The AirTAC Airtac MTD Multi-position Locking Cylinder MTD25X20S 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 MTD25X20S
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 MTD25X20S 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, handy 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, the trailing S means this cylinder includes 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. The trailing S adds the magnet for switch sensing; 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 holds the rod extended to clamp small parts by default and air pulls it clear for loading. The magnet allows position feedback from switches in the body slots.
Conveyor gate and stopper
Air lowers a stopper blade out of the product path and the spring raises it back. The 6-way fixing lets the body bolt to the top, side or underside of a compact conveyor frame.
Jig positioning pin
Air retracts a locating pin so a workpiece can seat in a jig, and the spring returns it each cycle. Switch sensing via the magnet confirms pin-in and pin-out positions.
FAQ
How does MTD25X20S differ from MTD25X20 and from an MSD push type?
MTD means single-acting pull type: air retracts the rod and a spring extends it. The 25 is the bore, 20 the stroke, and the trailing S means the magnet is included (MTD25X20 has none). An MSD25X20S would be the single-acting push type instead, where air extends the rod and the spring returns it.
What should I check before ordering for a tight space?
The square body fixes from 6 directions and cylinders can sit side by side, which saves panel space, but overall dimensions depend on the stroke, so confirm exact figures from the datasheet. Also note the compact cover limits over-long strokes, and confirm any side load with us before mounting.
