Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 80mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100
The AirTAC ACQJ80X80-100 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut on the extend side. This mechanism allows you to fine-tune the extend end position directly on your machine without swapping parts. With a full stroke of 80mm and a 100mm adjustment window, the usable extend range spans from 0mm up to 80mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore. At 0.5MPa it provides 2513.2N of push force and 2267.8N of pull force. The cylinder body incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration and includes magnetic-switch grooves, though this specific configuration ships without a magnet. The piston rod measures 25mm in diameter and uses a PT3/8 port.

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100 Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC machining center during setup. The external stop lets operators tweak the extend position for varying raw part dimensions without disassembling the fixture.
Product Changeover Diverter
Adjust the stroke length on packaging line diverters when switching between different carton sizes. The lock nut secures the new extend endpoint quickly for rapid format changeovers.
Press Stroke Limiting
Set precise lower-limit end positions on light assembly presses. The adjuster allows operators to test and lock trial end positions safely without needing to fabricate custom mechanical spacers.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100 the Right Cylinder?
When sizing this 80mm bore unit, consider the neighbouring capacities: stepping down to a 63mm bore yields 1558.6N push at 0.5MPa, whereas stepping up to a 100mm bore provides 3927.0N push. If your extend end position never varies, a fixed-stroke ACQ cylinder is simpler and suffices. For this adjustable variant, confirm your ordering essentials: 80mm bore, 80mm full stroke, 100mm window, female rod-end thread M16x2.0, and no magnet. Note that a plain ACQ-type cylinder will not hold a load on air loss; add an external rod lock or pilot-operated check valve if fail-safe holding is required.
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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-100 FAQ
The usable extend range is 0-80mm (full 80mm stroke minus the 100mm window). The retract stroke is unaffected. Force is identical to a standard ACQ: push is 2513.2N and pull is 2267.8N at 0.5MPa, push is 3518.5N at 0.7MPa, and maximum push is 513kgf at 1.0MPa.
An external M20x1.5 threaded stop with a lock nut limits the extend travel, changing only the stroke length, not the piston area or force. The cylinder uses fixed elastomer bumpers at both ends rather than adjustable air cushions. This model ships without a magnet, but the body retains sensor grooves for adding external switches.
