Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-20SBH
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-20SBH 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 ACQJ80X90-20SBH
The AirTAC ACQJ80X90-20SBH 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 range from 70 up to 90 mm on the machine without changing parts, while the retract stroke remains unaffected. It features a 25 mm piston rod, a PT3/8 port, and a male M22x1.5 rod-end thread that couples directly to the load.
Because the adjuster only changes stroke length and not the piston area, the output force is identical to a standard ACQ of the same bore. At 0.5 MPa it provides 2513.2 N push and 2267.8 N pull. The body includes fixed elastomer bumpers at each end for end-of-stroke deceleration, and the built-in piston magnet works with reed or electronic solid-state switches.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 90 mm |
| 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 ACQJ80X90-20SBH Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC mill during setup or when swapping workholding plates, avoiding the need to machine custom spacer blocks.
Product Changeover Diverters
Adjust the extend stop on packaging lines to hit different carton sizes, allowing rapid format changes without replacing the actuator.
Press Trial End Positions
Set trial end positions on assembly presses to test engagement depths, tweaking the 70 to 90 mm travel limit directly at the tooling.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-20SBH the Right Cylinder?
For lower force requirements, the 63 mm bore yields a 1558.6 N push at 0.5 MPa, whereas the larger 100 mm bore provides 3927.0 N. If your extend end position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering this adjustable unit, confirm the 80 mm bore, 90 mm full stroke, 20 mm window, the S magnet, 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 ACQJ80X90-20SBH FAQ
The usable extend range is 70 to 90 mm, set by the 20 mm window. Force is identical to a standard ACQ: push is 2513.2 N and pull is 2267.8 N at 0.5 MPa, push is 3518.5 N at 0.7 MPa, and maximum push is 513 kgf at 1.0 MPa.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke only; retract is unaffected. The cylinder uses fixed elastomer bumpers rather than adjustable air cushions. The S magnet works with reed or electronic solid-state switches.
