Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50SB 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 ACQJ32X200-50SB
The ACQJ32X200-50SB is a double-acting JIS compact cylinder built for applications requiring a long 200mm stroke with on-machine extend tuning. An external M12x1.25 threaded stop and lock nut lets you shorten the forward stroke by up to 50mm, yielding a usable extend range of 150-200mm. The retract distance remains fixed at the full 200mm. Because the piston area is unchanged, output force equals a standard ACQ of identical bore.
This made-to-order variant exceeds the 100mm standard maximum for a 32mm bore, placing it in the long-stroke category up to 300mm. It features a male M14x1.5 piston rod end (-B) for direct load coupling, an integrated magnet (-S) for electronic or reed switches, and fixed NBR elastomer bumpers. Operating pressure spans 0.15-1.0 MPa with a PT1/8 port.

| 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 (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 ACQJ32X200-50SB Is Used
Variable Length Stop Fixtures
Set precise 150-200mm extend endpoints on machining fixtures without machining new spacers when raw material dimensions shift.
Product Changeover Diverter
Quickly retune the forward stroke on packaging conveyors to accommodate different carton widths during production line changeovers.
Trial End Positioning
Dial in the exact extension point during automated test equipment prototyping before locking down the final mechanical stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-50SB the Right Cylinder?
When sizing this unit, stepping down to a 25mm bore yields 157.1N push at 0.5MPa, while a 40mm bore provides 628.3N; this 32mm unit delivers 402.1N push and 301.6N pull at 0.5MPa. If your machinery never requires end-position adjustments, a fixed-stroke ACQ cylinder suffices. To order, confirm the 32mm bore, 200mm full stroke, 50mm adjuster window, S magnet, and B male rod 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 ACQJ32X200-50SB FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The usable extend range is 150-200mm (200mm full stroke minus the 50mm adjustment window).
No, the adjuster only limits the forward stroke length; force remains identical to a standard ACQ because piston area is unchanged, and the retract stroke stays at the full 200mm. Deceleration relies on fixed elastomer bumpers, not adjustable air cushions.
