Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-30SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-30SB 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 ACQJ80X45-30SB
The AirTAC ACQJ80X45-30SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut on the rod-end side. This mechanism limits the extend travel, allowing you to fine-tune the end position directly on the machine. The usable extend range spans 15 to 45 mm, shortening the full stroke by up to a 30 mm window, 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, delivering 2513.2 N of push force at 0.5 MPa. The unit includes a male-thread piston rod end (M22x1.5) for direct load coupling and a built-in piston magnet for electronic or reed switches. It uses a fixed NBR elastomer bumper at each end for end-of-stroke deceleration across a 30 to 500 mm/s speed range.

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 ACQJ80X45-30SB Is Used
Machining Fixture Stops
Dial in the exact extend position of a clamping arm during a product-changeover on a CNC machining center without machining new stop collars.
Carton Sealing Alignment
Adjust the extend reach of a sealing flap press on a packaging line to accommodate varying box heights while maintaining full retract travel.
Assembly Press Trial
Safely test and set trial end positions for a pressing operation on an automated assembly line before locking the M20x1.5 adjuster nut in place.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-30SB the Right Cylinder?
When sizing this 80 mm bore actuator, consider the 63 mm bore which yields 1558.6 N of push force at 0.5 MPa, or the larger 100 mm bore providing 3927.0 N at 0.5 MPa. If your application requires a fixed extend length and never needs on-the-fly adjustments, a standard ACQ cylinder will suffice. To order this adjustable model correctly, confirm the 80 mm bore, 45 mm full stroke, 30 mm adjustment window, the -S magnet for sensing, and the -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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X45-30SB 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 15-45 mm (a 30 mm window off the 45 mm full stroke). The bore is 80 mm, the rod is 25 mm, the port is PT3/8, the male rod-end thread is M22x1.5, and the external adjuster thread is M20x1.5.
No, the external threaded stop alters only the extend stroke length, not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. Additionally, the -S magnet works with reed or electronic solid-state switches, but a plain ACQ will not hold its load on air loss, so an external rod lock is needed for fail-safe holding.
