Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75 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 ACQJ80X90-75
The AirTAC ACQJ80X90-75 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 travel from 15 mm up to the full 90 mm directly on your equipment, shortening the stroke by up to 75 mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, delivering 2513.2 N push at 0.5 MPa. The unit features a 25 mm piston rod, a PT3/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration. The external adjuster uses an M20x1.5 thread, and the body includes sensor grooves for adding switches later.

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 ACQJ80X90-75 Is Used
Press Fit Depth Tuning
Dial in exact insertion depths for bearing presses without machining new stop collars, allowing rapid recipe changes between product variants.
Product Changeover Stops
Modify the extend endpoint on packaging lines to accommodate different carton sizes quickly and accurately right at the machine.
Prototype Fixture Positioning
Establish optimal end positions during fixture R&D by testing various extend lengths from 15 to 90 mm before finalizing the design.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-75 the Right Cylinder?
If you need slightly less push force, the 63 mm bore provides 1558.6 N at 0.5 MPa, whereas stepping up to the 100 mm bore yields 3927.0 N. A fixed-stroke ACQ80X90 is sufficient if your extend position never requires field adjustments. When ordering this adjustable version, confirm the 80 mm bore, 90 mm full stroke, 75 mm window, female rod-end thread (M16x2.0), and that no magnet is included.
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 ACQJ80X90-75 FAQ
The usable extend range is 15-90 mm (90 mm full stroke minus the 75 mm window). It provides 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 adjuster only changes stroke length, not the force output.
An external M20x1.5 threaded stop with a lock nut limits the extend travel, while the retract stroke remains unaffected. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions. Note that this model ships without a sensor magnet, though the body retains grooves for adding reed or solid-state switches.
