The AirTAC Airtac MD Multi-Position Clamping Cylinder MD20X20S is a genuine MD multi-mount cylinder (double acting), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact.
The AirTAC MD20X20S is a compact square-body multi-mount cylinder that mounts side by side with other cylinders and can be fixed from 6 directions - front, back, left, right, top and bottom - to save space. Double acting with a 20 mm bore and 20 mm stroke, it provides a theoretical push thrust of 157.1 N at 0.5 MPa with a lower pull thrust, and uses a bumper for cushioning. Switch slots run around the body for position sensing.
This is a genuine AirTAC part from the MD standard multi-mount family. The S in the SKU means this cylinder is supplied WITH a magnet, so magnetic switches can detect piston position directly - no separate magnet option is needed. Operating pressure is 0.15-1.0 MPa (22-145 psi) on filtered air. We confirm dimensions, which vary with stroke, and sizing details 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.
Pick the 20 mm bore when your job calls for about 157.1 N of theoretical push force at 0.5 MPa; step up or down a bore to change the thrust. This MD model is double acting with a 20 mm stroke, within the 60 mm limit for bore 20, and the short-cover design warns against an over-long stroke. If rod rotation must be prevented, choose the MK no-rotating family rather than MD. The trailing S means the magnet is included on this SKU; drop it for an unmagnetized version. Thread is PT as standard, with G available. Side-load capacity and exact dimensions - route those to us to confirm from the datasheet.
With the built-in magnet feeding position feedback through the body slots, the cylinder drives the grip stroke of a compact pick-and-place head over 20 mm.
Fixed from its bottom or side face beside the belt, the cylinder raises and lowers a stopper blade, detecting extend and retract via the magnet.
Mounted side by side with twin cylinders in a fixture, it applies 157.1 N of push force at 0.5 MPa to press a bushing or cap into a small housing.
Yes. The trailing S in the SKU means this cylinder is supplied with a magnet, so magnetic switches in the slots around the body can signal piston position. The plain MD20X20 version is supplied without a magnet.
MD is the standard family, where some rod rotation is possible. MK is the no-rotating family, which adds a fixed rod and no-rotating plate to stop the rod turning. Choose MK when the orientation of the attached tooling must stay fixed, and confirm dimensions and side-load limits from the datasheet.
