Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-20B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-20B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm 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 ACQJ32X200-20B
The ACQJ32X200-20B is a double-acting, single-rod JIS compact cylinder built for applications requiring precise extend positioning. It features a 32 mm bore and a 200 mm full stroke. Because 200 mm exceeds the standard 100 mm maximum for this bore size, this unit is configured as a long-stroke, made-to-order variant. An external M12x1.25 threaded stop with a lock nut allows you to fine-tune the extend end position on the machine, providing a usable extend range of 180 to 200 mm. The retract stroke remains completely unaffected.
This model includes a male M14x1.5 piston rod end (-B) that couples directly to your load. The piston area is unchanged by the adjuster, meaning output force is identical to a standard ACQ of the same bore: 402.1 N push and 301.6 N pull at 0.5 MPa. It uses a PT1/8 port, operates at speeds from 30 to 500 mm/s, and relies on fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Note that this SKU ships without a magnet.

| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 (Ø32mm)
| 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.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-20B Is Used
Machining Center Changeover
Dial in the extend stop from 180 to 200 mm during CNC fixture swaps, accommodating varying part widths without machining new spacers.
Carton Forming Stops
Adjust the push-out end position on the fly for different box depths on a packaging line, using the external stop to set precise ejection distances.
Assembly Press Trial
Set trial end positions for pressing bearings on an assembly line, safely testing the 180-200 mm extend range before locking down the final stroke.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-20B the Right Cylinder?
When sizing this unit, consider the 402.1 N push force at 0.5 MPa. If your application requires less force, stepping down to a 25 mm bore yields 245.4 N push, while stepping up to a 40 mm bore provides 628.3 N push. If exact end-position tuning is unnecessary, a fixed-stroke ACQ cylinder will suffice. For ordering, confirm the 32 mm bore, 200 mm full stroke, 20 mm adjustable window, the male M14x1.5 rod thread (-B), and the absence of a magnet. Because this is a long-stroke configuration, ensure your mounting setup adequately supports the extended rod to prevent side-load binding.
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 ACQJ32X200-20B FAQ
This 32 mm bore cylinder has a 200 mm full stroke with a 20 mm adjustable window, yielding a usable extend range of 180-200 mm. It delivers 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 port size is PT1/8.
The external M12x1.25 threaded stop with lock nut limits the extend stroke length only; it does not alter piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions. This specific SKU lacks a sensor magnet.
