About the AirTAC MU20
The AirTAC MU20 is a small free-mount cylinder with a Ø20 mm bore: the square body can be fixed from any of its four sides, and several cylinders can be mounted side by side to save space. It is double acting: air drives the rod out and back.
A locating boss on the front cover makes positioning accurate, the bore is hard-anodized for wear resistance and the piston uses a compact bidirectional seal. The body has sensor grooves for CMSH, DMSH or EMSH sensors, which fit without brackets. It follows JIS standards and needs no lubrication.

Where the MU20 Is Used
Small pushers
Pushes, ejects and positions small parts.
Multi-cylinder banks
Several cylinders mount side by side in a row.
Jigs and fixtures
Four mounting faces fit tight spaces in a fixture.
Choosing the Right MU20 Configuration
Choose the stroke: the standard strokes on Ø20 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 mm. Maximum stroke is 50 mm; tolerance +1.0/0 mm.
S adds a magnet for position sensors.
Rod end: blank is a female thread, B a male thread. R is the axial mounting version; without R the body mounts transversely.
AirTAC MU20 FAQ
At 0.5 MPa the theoretical push force is 157.1 N and the pull force 117.8 N. Bore Ø20, rod Ø10 mm.
From any of the four sides of the body, or several side by side; on Ø12 to Ø20 the R version is for axial mounting.
MU is double acting. MSU is single acting, push type: air extends the rod and a spring returns it.
0.15-0.7 MPa, proof pressure 1.2 MPa, -20 to +70 °C, piston speed 30-500 mm/s, on air filtered to 40 µm.
