The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X15-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 15mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The AirTAC ACQJ40X15-10S is a double-acting JIS compact cylinder featuring a 40mm bore and a 15mm full stroke. An external threaded stop with a lock nut restricts the rod extension, yielding a usable extend range of 5 to 15mm. The retract distance remains unaffected by this adjustment. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This unit delivers 628.3N of push force and 527.8N of pull force at 0.5MPa, requiring 0.15-1.0MPa operating pressure. It incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The included -S piston magnet interfaces seamlessly with both reed and solid-state electronic switches via the body's built-in grooves.

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 | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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.

Rapidly reposition the extend end stop within the 5-15mm window on a machining line to accommodate different part lengths without fabricating new hard stops.
Dial in the exact packing density of a container by tweaking the external adjuster nut to vary the tamping depth during setup or material changes.
Establish trial end positions for pressing bearings or pins, allowing operators to fine-tune the stroke depth on the machine without swapping out components.
For lower force requirements, the 32mm bore yields 402.1N push at 0.5MPa, whereas stepping up to a 50mm bore provides 981.8N push. If the exact 15mm extend position is fixed permanently and never needs on-machine tweaking, a standard non-adjustable ACQ cylinder is sufficient. To order this adjustable variant correctly, verify the 40mm bore, 15mm full stroke, 10mm window, -S magnet, and the default female M8x1.25 rod-end thread.
Quick checklist
At 0.5MPa it provides 628.3N push and 527.8N pull force, and 879.6N push at 0.7MPa. The maximum push force is 128kgf at 1.0MPa. The usable extend range is 5-15mm, achieved by shortening the 15mm full stroke by up to the 10mm window.
No, the adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. The -S magnet works with both reed and electronic switches.
