Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10B 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 ACQJ80X70-10B
The AirTAC ACQJ80X70-10B 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 10 mm adjustment window, you can fine-tune the usable extend range from 60 mm up to 70 mm directly on the machine. The retract stroke remains completely unaffected by this mechanism.
Because the piston area stays the same, the output force is identical to a standard ACQ of this bore, delivering 2513.2 N of push force at 0.5 MPa. This unit includes 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, and the body retains sensor grooves even though this specific SKU ships without a magnet.

| 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 ACQJ80X70-10B Is Used
Machining Fixture Clamps
Dial in the exact clamping extension on CNC machining centers when raw material thicknesses vary, utilizing the 60-70 mm usable extend range to prevent over-travel.
Product Changeover Diverters
Adjust the extend stop on packaging line diverters during rapid product format changes without swapping out the entire cylinder assembly.
Press Trial End Positions
Safely test and set the final extend position on assembly presses during initial tooling setups, relying on the fixed elastomer bumper for end-of-stroke deceleration.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-10B the Right Cylinder?
If your application requires 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. Choose this 80 mm model when you need approximately 251 kgf of maximum thrust alongside precise extend-position tuning. If the end position never varies, a fixed-stroke ACQ cylinder is sufficient. For this adjustable variant, confirm your ordering essentials: 80 mm bore, 70 mm full stroke, 10 mm window, male rod thread (-B), and note that no magnet (-S) 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 ACQJ80X70-10B FAQ
The usable extend range is 60-70 mm (a 70 mm full stroke shortened by the 10 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 the maximum push is 513 kgf at 1.0 MPa.
The external M20x1.5 threaded stop with a lock nut limits how far the rod extends, shortening the stroke length only. It does not change the piston area, so the output force remains unchanged. The retract stroke is unaffected, and the cylinder uses a fixed elastomer bumper rather than an adjustable air cushion.
