Airtac MSD Multi-Position Fixed Cylinder MSD25X20
The AirTAC Airtac MSD Multi-Position Fixed Cylinder MSD25X20 is a genuine MD multi-mount cylinder (single acting, push type), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 179.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MSD Multi-Position Fixed Cylinder MSD25X20
The MSD25X20 is a single-acting, push-type multi-mount cylinder from AirTAC's MD family. Its compact square body fixes from six directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. In single-acting push service at 25 mm bore it develops a theoretical thrust of 179.1 N at 0.5 MPa, the cushion is a bumper, and the 20 mm stroke gives a longer reach within the single-acting table. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi) and 50-500 mm/s.
This is a genuine AirTAC part. The MD family is the standard series, where rod rotation is not restricted; the MK family is the no-rotating alternative with a fixed plate. This SKU carries no trailing S, so the unit is supplied without a magnet; an S-suffixed version adds one for switch detection. Overall dimensions at this stroke and sizing checks 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
Pick the bore for thrust: at 25 mm this single-acting push cylinder gives 179.1 N theoretical at 0.5 MPa. MSD is single acting, push type - air extends the rod; MTD would pull instead, MD double acting works both ways, and MK versions prevent rod rotation. Single-acting strokes top out at 20 mm at this bore, so this SKU sits at the upper end of the table and the compact covers cannot take an over-long stroke. Add S for a magnet and choose PT (default) or G thread - the M5x0.8 port serves bores 6-25.
Applications
Nest ejection of small parts
The 20 mm push stroke clears a finished part out of a machining or assembly nest so the next piece can load; the square body fixes from any of six directions.
Conveyor gate actuator
Mounted beside a conveyor, the cylinder pushes a light gate or diverter to sort small parts between lanes, with side-by-side mounting keeping the station compact.
Jig positioning
The cylinder nudges a workpiece against a jig stop before fastening; 6-direction fixing lets the body sit where the jig layout demands, not where the mount allows.
FAQ
Is the 20 mm stroke the longest available for this cylinder?
For single-acting versions at 25 mm bore the stroke table runs up to 20 mm, so this SKU is at the top of that range. If a longer stroke is needed, look at the double-acting MD/MK family - and remember the covers are compact, so very long strokes are not available on this series.
Can I mount several of these cylinders next to each other?
Yes. The multi-mount square body fixes from six directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space. Overall dimensions and side-load figures for a specific stroke should be confirmed from the datasheet.
