The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-50 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 50mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ32X50-50 is a double-acting JIS compact cylinder featuring an external extend stop. A threaded M12x1.25 adjuster and lock nut let you set the extend end position anywhere in a 0 to 50 mm usable range on the machine, while the retract stroke remains fixed at its 50 mm full length. You get on-the-fly end-position tuning without swapping parts.
Because the piston area is unchanged, force output is identical to a standard ACQ of this bore. At 0.5 MPa it delivers 402.1 N of push force and 301.6 N of pull force. The body uses fixed elastomer bumpers for end-of-stroke deceleration and includes sensor grooves, though this specific unit ships without a magnet. It operates at speeds from 30 to 500 mm/s.

Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

If your setup only needs a static 50 mm extend, a fixed-stroke ACQ32X50 is simpler and sufficient. Choose this ACQJ version when your fixture requires variable extend endpoints. For higher push force, the 40 mm bore yields 628.3 N at 0.5 MPa; for less force, the 25 mm bore yields 245.4 N. When ordering, confirm the 32 mm bore, 50 mm full stroke, 50 mm window, female M8x1.25 rod-end thread, and PT1/8 port.
Quick checklist
It provides 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 50 mm, and with the 50 mm window, the usable extend range is 0 to 50 mm.
An external M12x1.25 threaded stop with a lock nut limits how far the rod extends, shortening the stroke without changing the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected, and fixed elastomer bumpers decelerate the load at both ends.
