Airtac MTD Multi-position Locking Cylinder MTD20X20S
The AirTAC Airtac MTD Multi-position Locking Cylinder MTD20X20S is a genuine MD multi-mount cylinder (single acting, pull type), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 92.3 N of pull force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MTD Multi-position Locking Cylinder MTD20X20S
The MTD20X20S is a genuine AirTAC multi-mount cylinder: a compact square-body actuator that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with its neighbours to save space. This model is single acting, pull type, with a 20mm bore and 20mm stroke, so it suits short retract-stroke jobs such as releasing a part or pulling a gate clear. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to 70 C (0 to 150 C only with the optional high-temperature seal material), speed 50-500 mm/s, and cushions with a bumper. Magnetic-switch slots run around the body and guide precision is high without added lubricant.
This is a genuine AirTAC part. The MTD prefix marks the standard multi-mount family in single-acting pull form - rotation control is not part of this variant, which is the MK family's role. The trailing S in the code means this cylinder is built with a magnet for position sensing. We can confirm exact dimensions and sizing for your bore and stroke 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
Choose the bore for the force you need at 0.5 MPa; bore 20 is a mid-size choice for compact clamping and positioning. Here the acting type is fixed: MTD is single acting, pull type, so use it where the stroke must retract under air. Single-acting cylinders in this family cover strokes up to 20mm, so this 20mm stroke sits at the top of the range - the short cover design cautions against an over-long stroke. If you need rotation prevented, pick the MK family instead of MD; if you need a double-acting or adjustable-stroke cylinder, look at MD, MDD or MDJ. The trailing S gives you a magnet; omit it if sensing is not needed. Port thread is PT as standard, with G available - check the thread code when ordering. Side-load capability and exact per-stroke dimensions come from the datasheet; ask us to confirm them.
Applications
Small-parts clamp release
Single-acting pull action retracts a compact clamping pad to free a finished part, with the 20mm stroke clearing the fixture and the square body fixed from 6 directions in a tight cell.
Sliding-gate stopper
Pulls a stopper or gate bar out of the conveyor path at a workstation; side-by-side mounting lets several gates share one machine rail, and the magnet signals gate-open position.
Jig retract on an assembly fixture
Retracts a locating pin or jig arm between assembly cycles. Multi-mount fixing from any of 6 directions makes alignment on the jig plate straightforward in cramped fixtures.
FAQ
What does the S at the end of MTD20X20S mean?
The trailing S indicates this cylinder is supplied with a magnet, so magnetic switches seated in the slots around the body can sense piston position. The same model without the S is supplied without a magnet. Port thread is PT as standard; a G thread is chosen by adding G to the code.
Where can I mount this cylinder, and how do I check dimensions and side load?
The square body can be fixed from 6 directions - front, back, left, right, top and bottom - and cylinders can sit side by side to save space. Because overall dimensions and allowable side-load figures depend on the bore and stroke, confirm them from the datasheet; we can supply it on request.
