Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-75B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-75B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 70mm 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 ACQJ80X70-75B
The AirTAC ACQJ80X70-75B is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You can fine-tune the usable extend range from 0 mm up to the full 70 mm directly on your machinery without swapping components. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force is identical to a standard ACQ of this bore size, delivering 2513.2 N push at 0.5 MPa. This variant includes a male M22x1.5 rod-end thread for direct load coupling and uses a PT3/8 port. It relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion.

| Adjuster thread | M20×1.5 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| Rod thread | M16×2.0 (F) / M22×1.5 (B) |
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 ACQJ80X70-75B Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC machining center during part family changeovers without machining new spacer blocks.
Carton Forming Adjustments
Vary the tucking arm extension on a packaging line to accommodate different box depths rapidly on the fly.
Press Pin Insertion Depth
Set precise downward travel for pressing pins into assemblies, allowing operators to test multiple insertion depths easily.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-75B the Right Cylinder?
When sizing this 80 mm bore actuator, stepping down to a 63 mm unit drops the 0.5 MPa push force to 1558.6 N, while moving up to a 100 mm bore increases it to 3927.0 N. If your application never requires end-position variance, a fixed-stroke ACQ cylinder provides the same holding power in a simpler package. To order this adjustable version correctly, confirm the 70 mm full stroke, the 75 mm adjustment window, the male M22x1.5 rod thread, and note that this specific SKU ships without a magnet.
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 ACQJ80X70-75B FAQ
This 80 mm bore cylinder delivers a push force of 2513.2 N and a pull force of 2267.8 N at 0.5 MPa, with a push of 3518.5 N at 0.7 MPa. The maximum push is 513 kgf at 1.0 MPa. The usable extend range is 0-70 mm, created by the 75 mm adjustment window on the 70 mm full stroke.
The external M20x1.5 threaded stop with lock nut physically limits how far the rod extends, changing only the stroke length while leaving the output force unchanged. The cylinder uses fixed elastomer bumpers for end-of-stroke deceleration. Note that a plain ACQ-type cylinder will not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
