AirTAC MSA Series Single-Acting Mini Cylinders

The MSA is AirTAC's standard round-body mini cylinder in single-acting push form: compressed air extends the rod, and a return spring retracts it to its home position the moment air is removed. The range runs five bores - 16, 20, 25, 32 and 40 mm - with thrust at 0.5 MPa of roughly 60 N (16 mm, 6 mm rod) up to 440 N (40 mm, 16 mm rod), all measured net of the return spring. Strokes are short by design: up to 100 mm on the 16 mm bore and up to 150 mm on the 20-40 mm bores.

Every MSA shares the same construction: a high-precision stainless-steel barrel with rolling-packed aluminium-alloy front and back covers and a stainless-steel block, plus a carbon-steel piston rod hard-chrome plated to 20 um. The piston uses a two-way seal that also stores grease, so the cylinder runs on air filtered to 40 um with no lubrication required. Working pressure is 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa, temperature -20 to +70 C, speed 50-800 mm/s, and cushioning is by fixed bumper pads. Ports are M5x0.8 on the 16 mm bore and 1/8" on the 20-40 mm bores. The catalogue carries no standard designation (it is not ISO 6432 or JIS), so specify MSA models by AirTAC code.

A magnet is built in as standard on every MSA, so the -S option simply enables CMSG, DMSG or EMSG reed or solid-state switches for end-of-stroke sensing. If you need a powered return, step to the double-acting MA or MAC series; for single-acting pull (spring extends, air retracts), the MTA is the counterpart.
