Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-30
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 45mm 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 ACQJ80X45-30
This double-acting single-rod JIS compact cylinder features an external threaded stop with a lock nut, allowing you to fine-tune the extend end position directly on your equipment. The full stroke is 45 mm, and the 30 mm adjustment window lets you set the usable extend range from 15 mm up to 45 mm. The retract stroke remains completely unaffected by this mechanism.
Because the piston area stays constant, the output force is identical to a standard ACQ of the same bore, delivering 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. It operates at speeds of 30-500 mm/s and includes integrated magnetic-switch grooves, though this specific configuration ships without a magnet.

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 ACQJ80X45-30 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC milling fixture during product-changeover without machining new stop collars or swapping cylinders.
Package Diverter Setup
Adjust the pusher arm extension on a packaging line conveyor to accommodate varying carton widths on the fly, ensuring precise sorting.
Assembly Press Tria
Establish trial end positions for pressing bearings on an assembly line, tweaking the 15-45 mm extend range until the optimal seating depth is found.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-30 the Right Cylinder?
If your application requires less thrust, stepping down to the 63 mm bore yields 1558.6 N push at 0.5 MPa, whereas the 100 mm bore provides 3927.0 N push if you need higher force. If you do not require on-the-fly end-position tuning, a fixed-stroke ACQ cylinder will achieve the same clamping force. When ordering this adjustable variant, verify your required full stroke (45 mm), the adjustment window (30 mm), the 80 mm bore, the PT3/8 port, and the female M16x2.0 rod-end 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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-30 FAQ
The 80 mm bore provides 2513.2 N push and 2267.8 N pull at 0.5 MPa, 3518.5 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The full stroke is 45 mm with a 30 mm window, allowing a usable extend range of 15-45 mm.
The external M20x1.5 threaded stop and lock nut limit the extend distance without altering the piston area, meaning force is unchanged. Deceleration relies on a fixed elastomer bumper, not an adjustable air cushion. Note that a plain ACQ-type cylinder will not hold its load on air loss; use an external rod lock for fail-safe holding.
