The Airtac ACQ50X15S is a double-acting compact cylinder from the AirTAC ACQ series, built to JIS, with a 50 mm bore, 15 mm stroke, female (internal) thread on the piston rod and with magnet (S). The short body is held together by C-clips, the bore is roller-burnished and hard-anodised, and switch slots run around the barrel.
Reading the code: ACQ = compact cylinder (double acting), 50×15 = bore x stroke in mm, S = with magnet; no B means female rod thread; no further suffix means no mounting accessory and the standard PT port thread.

Typical applications
- Lifting and indexing units on assembly lines
- Gate and flap actuation on packaging machines
- Clamping and locating on jigs and fixtures
- Punching, marking and pressing stations
- Like-for-like replacement of an Airtac ACQ50X15S
Compatibility and replacement
ACQ cylinders follow the JIS compact-cylinder standard, so the 50 mm bore shares its basic envelope with JIS compact cylinders of other brands; still compare overall length, rod thread and mounting holes before swapping makes. If you need a male rod thread instead, the same size is ordered as ACQ50X15SB (magnet and male thread) or ACQ50X15B (male thread, no magnet).
Frequently asked questions
What is the difference between ACQ50X15S and ACQ50X15B?
S means the piston carries a magnet for cylinder switches; B means the piston rod has a male thread instead of a female one. This ACQ50X15S has a magnet and a female thread.
How fast can it run?
AirTAC gives a speed range of 30-500 mm/s for this bore, with bumper cushioning. Use speed-control fittings to set the speed and keep impact at the stroke ends low.
How much force does it give?
At 0.5 MPa the 50 mm bore gives about 981.7 N pushing and 824.7 N pulling (20 mm rod), per AirTAC data. Size with spare capacity if the load varies.
