The Airtac ACQ40X30B is a double-acting compact cylinder from the AirTAC ACQ series, built to JIS, with a 40 mm bore, 30 mm stroke, male (external) thread on the piston rod (B) and without magnet. 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), 40×30 = bore x stroke in mm, B = male rod thread; no S means no magnet; no further suffix means no mounting accessory and the standard PT port thread.

- Punching, marking and pressing stations
- Short-stroke pushers and stoppers in tight spaces
- Mould and tooling clamps
- Like-for-like replacement of an Airtac ACQ40X30B
Compatibility and replacement
ACQ cylinders follow the JIS compact-cylinder standard, so the 40 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. Because this unit has no magnet, cylinder switches cannot sense it. If you need sensing with a male rod end, order ACQ40X30SB.
Frequently asked questions
What is the difference between ACQ40X30B and ACQ40X30S?
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 ACQ40X30B has a male thread and no magnet.
Is ACQ40X30B a standard stroke?
30 mm is a standard stroke for the 40 mm bore in the AirTAC catalog, where the standard range goes up to 100 mm.
Which fittings do I need?
The ports are 1/8″ with standard PT thread; G or NPT threads are a separate order code. Use push-in or speed-control fittings of the same thread and tube size suited to the flow.
