Airtac MSD Multi-Position Fixed Cylinder MSD25X20S
The AirTAC Airtac MSD Multi-Position Fixed Cylinder MSD25X20S 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 MSD25X20S
The MSD25X20S 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. The trailing S on this SKU means the unit is supplied with a magnet 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. The S suffix supplies the magnet; if you do not need switch detection, the plain MSD25X20 is the same unit without it. Choose PT (default) or G thread - the M5x0.8 port serves bores 6-25.
Applications
Small-parts clamping with position check
The magnet lets a switch confirm the clamp is fully advanced while the 20 mm push holds a small part in its fixture; 6-direction fixing suits crowded jigs.
Stopper with end-position sensing
The cylinder pushes a stopper up beside a conveyor to hold small parts, and the built-in magnet signals when the stopper is seated - no external sensor bracket needed.
Indexing pusher
Mounted side by side along a dial or linear table, the cylinder advances an indexing pin each cycle; compact bodies keep the pitch between stations small.
FAQ
Why choose MSD25X20S over the plain MSD25X20?
The only difference is the magnet: the trailing S means this unit carries a magnet, so magnetic switches can be seated in the body slots for end-of-stroke detection. If no switch sensing is required, the MSD25X20 without the S is supplied without a magnet.
Are the stroke and mounting dimensions the same across the MD family?
The 20 mm stroke is the maximum for single-acting bores of this size, and the compact covers mean an over-long stroke is not available on this series. For exact overall dimensions at this stroke and any side-load limits, confirm from the datasheet or ask us.
