Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 200mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10S
The ACQJ40X200-10S is a double-acting, single-rod JIS compact cylinder built for applications requiring a precise, externally tuned extend endpoint. As a long-stroke made-to-order variant, its 200 mm travel exceeds the standard 100 mm maximum for this 40 mm bore. An external M12x1.25 threaded stop and lock nut lets you shorten the outward stroke by up to 10 mm, yielding a usable extension range of 190 to 200 mm. The retract stroke remains fixed at the full 200 mm.
Because the adjustment limits travel without altering the 40 mm piston area, output force stays identical to a standard ACQ unit. You get 628.3 N of push and 527.8 N of pull at 0.5 MPa, or 879.6 N push at 0.7 MPa. The body features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and includes a piston magnet (-S) for position sensing. This magnet is compatible with both reed and solid-state electronic switches.

| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| Rod thread | M8×1.25 (F) / M14×1.5 (B) |
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.
Theoretical Output Force (Ø40mm)
| 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.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10S Is Used
Machining Center Clamps
Dial in exact material clamping positions on CNC fixtures without machining new spacers, using the external stop to compensate for varying raw part widths.
Carton Forming Stops
Adjust the pusher end point on the fly during packaging line changeovers to accommodate different corrugated box depths while maintaining full retract travel.
Assembly Press Stations
Establish trial end positions for pressing bearings or pins, allowing operators to fine-tune the 190-200 mm extension window safely before finalizing the mechanical setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10S the Right Cylinder?
When sizing this actuator, compare its 628.3 N push force at 0.5 MPa against the neighboring bores: a 32 mm bore provides 402.1 N, while a 50 mm bore yields 981.8 N. Choose this specific 40 mm model when your load requires roughly 64 kgf of thrust within a compact footprint. If your machine never requires end-position tuning, a fixed-stroke standard ACQ cylinder will suffice. For ordering, confirm the 40 mm bore, 200 mm full stroke, 10 mm adjuster window, the -S magnet option, and the default female M8x1.25 rod-end thread.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10S FAQ
This 40 mm bore cylinder delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The full stroke is 200 mm, but the external adjuster allows you to shorten the extend stroke by up to 10 mm, creating a usable extend range of 190 to 200 mm.
The external M12x1.25 threaded stop with lock nut mechanically limits how far the rod extends, changing only the stroke length and not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not an adjustable air cushion. Note that this is a long-stroke variant exceeding the 100 mm standard maximum, and the cylinder will not hold its load on air loss without an external rod lock.
