About the AirTAC MU8
The AirTAC MU8 is a small free-mount cylinder with a Ø8 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.
