Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75B 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 ACQJ80X90-75B
The AirTAC ACQJ80X90-75B is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to precisely limit the extend stroke. You can fine-tune the end position on the machine, yielding a usable extend range of 15 to 90 mm from the 90 mm full stroke. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 2513.2 N push and 2267.8 N pull at 0.5 MPa. This 80 mm bore unit uses a 25 mm rod, a PT3/8 port, and ships with a male M22x1.5 rod-end thread for direct load coupling. 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 |

| 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 ACQJ80X90-75B Is Used
Machining Fixture Stops
Dial in the extend position from 15 to 90 mm on a CNC fixture to accept different raw casting sizes without machining new stop blocks.
Product Changeover Diverters
Adjust the extend stroke on a packaging line diverter to route varying box widths on the fly without swapping the cylinder.
Press Trial Positions
Set trial end positions on an assembly press to test crimp depths, relying on the 513 kgf max push at 1.0 MPa for secure forming.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75B the Right Cylinder?
When sizing this 80 mm bore actuator, stepping down to a 63 mm bore yields 1558.6 N push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927.0 N push at 0.5 MPa. Choose this adjustable model when your application requires varying extend end positions; if the 90 mm stroke is fixed and never needs tuning, a standard ACQ cylinder is sufficient. Confirm your ordering essentials: 80 mm bore, 90 mm full stroke, 75 mm window, male B rod thread, and note this unit ships without a -S sensor 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 ACQJ80X90-75B FAQ
The force is identical to a standard ACQ of this bore: 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, and with the 75 mm window, the usable extend range is 15 to 90 mm.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke length only; it does not change the piston area or force. Deceleration is handled by a fixed NBR elastomer bumper, not an adjustable air cushion. Note that a plain ACQ-type cylinder does not hold its load on air loss, so for a fail-safe hold you should add an external rod lock or pilot-operated check valve.
