Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-75B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-75B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 75mm 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 ACQJ80X75-75B
The ACQJ80X75-75B is a double-acting JIS compact cylinder featuring a male-threaded piston rod end (M22x1.5) for direct load coupling. An external M20x1.5 threaded stop and lock nut restricts the extend travel, providing a usable extend range of 0-75mm from the 75mm full stroke. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, yielding 2513.2N push and 2267.8N pull at 0.5MPa. The unit relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Operating pressure spans 0.15-1.0MPa, and the body features integrated 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 ACQJ80X75-75B Is Used
Press Fixture Tuning
Dial in the exact clamping extension on a multi-product press without machining custom spacers, switching parts rapidly during product changeover.
Diverter Gate Setup
Adjust the pusher stroke on a packaging line to accommodate varying carton sizes, ensuring precise diverting without repositioning the cylinder mount.
Machine Trial Positions
Test different end stop positions during initial equipment commissioning to find the optimal mechanical engagement before locking the nut down.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-75B the Right Cylinder?
When sizing this 80mm bore unit, consider the adjacent 63mm bore yielding 1558.6N push or the 100mm bore yielding 3927.0N push at 0.5MPa to match your load requirements. If your application requires a fixed extend position that never varies, a standard ACQ cylinder without the external adjuster will suffice. For ordering, confirm the 75mm full stroke, 75mm adjustment window, the male rod thread (-B), and whether you need the -S magnet option for position sensing. Remember that a plain ACQ-type cylinder does not hold its load on air loss; specify 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 ACQJ80X75-75B FAQ
This cylinder provides 2513.2N push and 2267.8N pull at 0.5MPa, 3518.5N push at 0.7MPa, and a maximum push of 513kgf at 1.0MPa. The full stroke is 75mm with a 75mm adjustment window, allowing the usable extend range to be set anywhere from 0 to 75mm.
The external M20x1.5 threaded stop limits only the extend stroke length without altering the piston area, so force remains identical to a standard ACQ. Deceleration relies on a fixed NBR elastomer bumper rather than an adjustable air cushion, and the cylinder will not hold its load on air loss without an external rod lock.
