Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10SB 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 ACQJ40X200-10SB
The ACQJ40X200-10SB is a double-acting, single-rod JIS compact cylinder built for applications requiring precise extend positioning. An external M12x1.25 threaded stop and lock nut limits the rod extension, allowing you to fine-tune the usable extend stroke from 190 mm up to the full 200 mm directly on the machine. The retract stroke remains completely unaffected by this adjustment. This unit includes a male M14x1.5 piston rod end and a built-in magnet (-S) for position sensing.
Featuring a 40 mm bore, this long-stroke made-to-order variant exceeds the standard 100 mm maximum, extending up to 300 mm for specialized reach requirements. The piston area is unchanged by the adjuster, meaning output force is identical to a standard ACQ: 628.3 N push and 527.8 N pull at 0.5 MPa. It uses a PT1/8 port, operates between 0.15 and 1.0 MPa, and relies on fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions.

| 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 ACQJ40X200-10SB Is Used
Machine Tending Changeovers
Dial in the extend stop from 190 to 200 mm during automated lathe changeovers to accommodate different part lengths without machining new spacers.
Variable Carton Positioning
Fine-tune the pusher endpoint on a packaging line to handle varying box dimensions on the fly, ensuring precise alignment before sealing.
Extended-Reach Fixtures
Utilize the 200 mm long-stroke capacity to reach across wider machine beds while retaining the ability to back off the final 10 mm for setup calibration.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-10SB the Right Cylinder?
When sizing this actuator, compare its 628.3 N push force at 0.5 MPa against neighboring bores: a 32 mm bore provides 402.1 N, while a 50 mm bore yields 981.8 N. If your extend position never varies, a fixed-stroke ACQ cylinder is simpler and sufficient. However, if trial end positions or product changeovers require on-the-fly adjustments without swapping parts, this ACQJ is the correct choice. Confirm your ordering essentials: 40 mm bore, 200 mm full stroke, 10 mm adjuster window, -S magnet for electronic or reed switches, and -B male rod thread.

- ✓ 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 ACQJ40X200-10SB 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, giving a usable extend range of 190-200 mm.
No, the adjuster changes only the stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, not an adjustable air cushion. Note that it will not hold a load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
