Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50B 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 ACQJ80X80-50B
The AirTAC ACQJ80X80-50B is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 30 mm up to the full 80 mm stroke directly on the machine, while the retract stroke remains unaffected. It features a 25 mm piston rod and a male M22x1.5 thread end for direct load coupling.
Because the adjuster only changes stroke length and not the piston area, the output force is identical to a standard ACQ of the same 80 mm bore. The cylinder uses a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. It operates with PT3/8 ports and includes sensor 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 ACQJ80X80-50B Is Used
Machining Fixtures
Dial in the exact clamping extend position on machining fixtures during part-changeover without machining new spacers.
Product Diverters
Adjust the extend reach of conveyor sorting gates on-site to handle varying package widths efficiently.
Assembly Presses
Set precise trial end positions for pressing operations on automated assembly lines to prevent component damage.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-50B the Right Cylinder?
If your application requires less force, the 63 mm bore variant provides 1558.6 N push at 0.5 MPa, whereas stepping up to the 100 mm bore yields 3927.0 N. A standard fixed-stroke ACQ80 is sufficient if your end position never varies. When ordering this adjustable unit, confirm the 80 mm bore, 80 mm full stroke, 50 mm window, the male M22x1.5 rod thread, and whether you need the magnet option for sensors.
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 ACQJ80X80-50B FAQ
It delivers 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 usable extend range is 30-80 mm, adjusted via the M20x1.5 external stopper, while the retract stroke remains fixed at 80 mm.
No, the force is identical to a standard ACQ because the adjuster only changes stroke length, not piston area. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
