Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-75SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-75SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 80mm 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 ACQJ80X80-75SB
The AirTAC ACQJ80X80-75SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend range from 5 mm up to the full 80 mm directly on the machine, while the retract stroke remains completely unaffected. This bore 80 unit delivers a push force of 2513.2 N at 0.5 MPa, identical to a standard ACQ because the piston area is unchanged; the adjuster alters stroke length only.
It includes a -S magnet for use with reed or solid-state electronic switches, and a -B male piston rod end (M22x1.5) that couples directly to your load. The body uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Operating pressure spans 0.15-1.0 MPa, and the PT3/8 port handles standard pneumatic supply.

| 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 ACQJ80X80-75SB Is Used
Machining Fixture Clamps
Dial in the exact 5-80 mm extend position for varying raw casting sizes on a CNC machining center without swapping out cylinder bodies or stop parts.
Carton Forming Stops
Adjust the pusher end point on the fly during packaging product changeovers to accommodate different package depths while maintaining 2513.2 N of clamping force.
Assembly Press Trial
Set trial end positions for pressing bearings on an automated line, allowing operators to safely test stroke limits before locking down the M20x1.5 adjuster nut.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-75SB the Right Cylinder?
When sizing this 80 mm bore unit, stepping down to a 63 mm bore drops the 0.5 MPa push force to 1558.6 N, whereas stepping up to a 100 mm bore yields 3927.0 N. If your application never requires altering the end position, a fixed-stroke ACQ cylinder is sufficient and more compact. To order this adjustable version correctly, confirm the 80 mm bore, the 80 mm full stroke, the 75 mm adjustable window, the S magnet, and the B male rod thread. Note that a plain compact cylinder will drift and lose its load on air loss; for fail-safe holding, specify an external rod lock or pilot-operated check valve.
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 ACQJ80X80-75SB FAQ
At 0.5 MPa, the push force is 2513.2 N and the pull force is 2267.8 N; at 0.7 MPa, the push force is 3518.5 N. The maximum push force is 513 kgf at 1.0 MPa. The full stroke is 80 mm with a 75 mm adjustable window, giving a usable extend range of 5-80 mm.
The external M20x1.5 threaded stop with lock nut physically limits how far the rod extends, shortening the stroke without changing the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions. The built-in -S magnet works with reed or electronic solid-state switches for position sensing.
