Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-30SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-30SB 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 ACQJ80X70-30SB
The AirTAC ACQJ80X70-30SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the EXTEND end position. With a full stroke of 70 mm and a 30 mm adjustment window, you can tune the usable extend range from 40 mm up to 70 mm directly on the machine without changing parts. The RETRACT stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This model delivers 2513.2 N of push force and 2267.8 N of pull force at 0.5 MPa, scaling to 3518.5 N push at 0.7 MPa, with a maximum push capacity of 513 kgf at 1.0 MPa. It includes the -S magnet for reed or solid-state switches and a -B male piston rod end (M22x1.5) that couples directly to your load. The unit uses a PT3/8 port, features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, and relies on an M20x1.5 adjuster thread for stroke modifications.

| Full stroke | 70 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 |

| 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 ACQJ80X70-30SB Is Used
Machining Changeover Stops
Dial in the extend endpoint on the fly during CNC fixture changeovers to accommodate varying part lengths without swapping out the cylinder body.
Packaging Tucking Arms
Adjust the tucking depth for different carton sizes on a packaging line, using the external stop to set precise material fold positions.
Press Trial Positions
Test press end positions on assembly equipment by fine-tuning the extend stroke within the 40-70 mm range before locking the nut for production.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-30SB the Right Cylinder?
When sizing this 80 mm bore actuator, consider the adjacent bores: dropping to a 63 mm cylinder reduces push force to 1558.6 N at 0.5 MPa, while stepping up to a 100 mm bore increases it to 3927.0 N. Choose this ACQJ variant when setup-varying fixtures or product-changeover stops require trial end positions; a fixed-stroke ACQ suffices if the extend endpoint never changes. Confirm your ordering essentials: 80 mm bore, 70 mm full stroke, 30 mm window, -S magnet, and -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 ACQJ80X70-30SB FAQ
At 0.5 MPa it provides 2513.2 N push and 2267.8 N pull force, and 3518.5 N push at 0.7 MPa. The maximum push is 513 kgf at 1.0 MPa. The full stroke is 70 mm with a 30 mm window, yielding a usable extend range of 40-70 mm.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke, allowing on-machine tuning without changing parts. The adjuster changes stroke length only, so force remains identical to a standard ACQ. The retract stroke is unaffected, and a fixed elastomer bumper decelerates the load at the ends.
