The AirTAC Airtac MTD Multi-position Locking Cylinder MTD20X20 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.
The MTD20X20 is an AirTAC multi-mount cylinder: a compact square-body cylinder that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side with identical units to save space. This version has a 20 mm bore with a 20 mm stroke, the longest stroke offered in the single acting range of this series, and is single acting, pull type: air pressure retracts the rod and the internal spring returns it. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), operates from -20 to 70 C, reaches speeds of 50-500 mm/s, and is cushioned by an elastic bumper. As there is no magnet code, this SKU is supplied without a magnetic piston.
This is a genuine AirTAC part from the MD multi-mount family, the standard series where the rod is free to rotate; if you need the rod or plate held against rotation, choose the MK no-rotating series instead. The body carries slots for magnetic switches, but this non-magnet SKU will not trigger them. Construction is typically aluminium alloy body, covers and piston with a stainless or S45C rod and NBR seals. We will 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.
Choose the bore for the thrust your job needs; for this pull-type single acting variant, confirm the pull-side thrust from the datasheet, noting that the pull side delivers less force than the push side of a comparable push-type cylinder. Pick the acting type deliberately: double acting (MD), single acting push (MSD), single acting pull (MTD, this model), double rod (MDD) or adjustable stroke (MDJ). This 20 mm stroke is the maximum for the single acting versions of the series; the short cover means no longer stroke exists here, so size your tooling to it rather than asking for extra travel. Magnet is added only with the S suffix (MTD20X20S); this SKU has none. Port thread is PT as standard, or G with the G suffix, both M5x0.8 on this bore. Route side-load questions to us and the datasheet.
Bolted through the front face of a compact fixture, the 20 mm bore rod pushes a finished small part off a nest as air is applied; the spring pulls the plunger back ready for the next part, using the full 20 mm stroke available to single acting units.
Mounted top-down beside a light conveyor, the cylinder swings or lifts a short divert gate out of the lane under air pressure; loss of air lets the spring restore the gate to its default guiding position, making the safe state self-restoring.
Fixed from the bottom face of an assembly pallet, the rod raises a locating pad to lift a workpiece onto a datum; the 20 mm stroke gives just enough lift for seating small parts while keeping the unit hidden inside the pallet footprint.
Yes. In the MD/MK multi-mount series, single acting versions such as the MTD20X20 are limited to strokes up to 20 mm because of the short cover, so this model is already at the top of the single acting range. If you need more travel at a 20 mm bore, move to the double acting MD or no-rotating MK versions, which are offered up to 60 mm at this bore.
The compact square body can be fixed from 6 directions (front, back, left, right, top and bottom), and units can be mounted side by side to save space, which is the core benefit of the multi-mount design. Note that side-load capability and exact dimensions for this stroke are not listed on this page; confirm them from the datasheet.
