Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-50
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-50 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 ACQJ40X200-50
The ACQJ40X200-50 is a double-acting, single-rod JIS compact cylinder built for specialized long-stroke applications. It features a 200mm total stroke and an external M12x1.25 threaded stop with a lock nut on the rod-end side. This mechanism limits the outward travel, providing a usable extend range of 150 to 200mm, while the retract stroke remains completely unaffected.
Because the adjuster only restricts travel length and not the piston area, output power matches a standard ACQ exactly. You get 628.3N of push force at 0.5MPa. The unit relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. Operating speed spans 30-500mm/s, and the body includes sensor grooves, though this specific configuration ships without a magnet.

| 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 ACQJ40X200-50 Is Used
Multi-Depth Machining Stops
Dial in exact material clamping positions on CNC mills. The external stop allows operators to shift the extend endpoint between 150mm and 200mm for different part lengths without swapping cylinders.
Packaging Line Changeover
Accommodate various carton sizes on automated packaging conveyors. Fine-tune the pushing stroke rapidly during product transitions to maintain precise indexing without mechanical rebuilds.
Extended Reach Assembly
Drive long-trroke tooling or grippers across automotive assembly stations. The 200mm travel handles distant workpieces, while the adjuster dials back the stroke for closer operational zones.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X200-50 the Right Cylinder?
When sizing this 40mm bore actuator, consider the neighbouring capacities: a 32mm bore yields 402.1N push, whereas a 50mm bore provides 981.8N at 0.5MPa. If your process never requires altering the end position, a fixed-stroke ACQ cylinder will suffice. For setups needing positional flexibility, verify your ordering parameters including the 200mm full stroke, 50mm window, female M8x1.25 rod-end thread, and PT1/8 port.
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 ACQJ40X200-50 FAQ
This cylinder delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The full stroke is 200mm with a 50mm adjustable window, allowing an extend range of 150-200mm. It features a 16mm rod, PT1/8 port, female M8x1.25 rod-end thread, and an M12x1.25 adjuster thread.
The external threaded stop mechanically limits how far the rod extends without changing the piston area, meaning force output remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions. Note that a plain ACQ-type cylinder will not hold its load on air loss; the rod drifts, so an external rod lock or pilot-operated check valve is recommended for fail-safe holding.
