Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 90mm 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 ACQJ80X90-50SB
The ACQJ80X90-50SB 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 40 mm up to the full 90 mm stroke directly on the machine without swapping parts. The RETRACT stroke remains completely unaffected by this adjustment.
Because the adjuster only changes stroke length and not the piston area, the output force is identical to a standard ACQ of the same bore. This 80 mm bore model features a 25 mm piston rod, a PT3/8 port, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. The -S option includes a built-in piston magnet compatible with reed or electronic solid-state switches, while the -B option provides a male M22x1.5 rod-end thread for direct load coupling.

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 ACQJ80X90-50SB Is Used
Machining Fixture Stops
Dial in the extend position from 40 to 90 mm on a CNC machining fixture to accommodate varying raw casting dimensions without fabricating new stop collars.
Packaging Changeover
Adjust the extend end stop on a packaging line's carton sealing head during product format changeovers, saving downtime by turning the external M20x1.5 adjuster nut.
Press Fit Positioning
Set precise trial end positions for a press-fit assembly station, relying on the fixed elastomer bumper to decelerate the 3518.5 N force at 0.7 MPa before the final fit.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50SB the Right Cylinder?
When sizing this bore, note it delivers 2513.2 N push and 2267.8 N pull at 0.5 MPa. If your application requires less force, stepping down to a 63 mm bore yields 1558.6 N push at 0.5 MPa, whereas stepping up to a 100 mm bore provides 3927.0 N push at 0.5 MPa. A fixed-stroke ACQ cylinder is sufficient if your extend position never needs on-machine variation. To order this adjustable version correctly, confirm the 80 mm bore, 90 mm full stroke, 50 mm adjustable window, along with the -S magnet and -B male rod thread options.
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 ACQJ80X90-50SB 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 full stroke is 90 mm with a 50 mm adjustable window, giving a usable extend range of 40-90 mm.
No, the adjuster changes stroke length only, so force remains identical to a standard ACQ of the same bore. The extend stop uses an external M20x1.5 thread with a lock nut, and fixed elastomer bumpers decelerate the load near stroke end. For fail-safe load holding on air loss, use an external rod lock.
