Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100SB 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 ACQJ80X90-100SB
The AirTAC ACQJ80X90-100SB is a double-acting JIS compact cylinder featuring an external M20x1.5 threaded stop and lock nut to limit the extend end position. You can fine-tune the usable extend range from 0 up to 90 mm directly on your machinery without swapping components, while the retract stroke remains completely unaffected.
Because the piston area stays constant, output force is identical to a standard ACQ of this bore, delivering a push of 2513.2 N at 0.5 MPa. This 80 mm bore unit includes a male M22x1.5 rod end for direct load coupling, a PT3/8 port, and an internal piston magnet compatible with reed or solid-state switches. It relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion.

| Model | Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100SB |
|---|---|
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ80X90-100SB Is Used
Machining Fixture Stops
Dial in the exact extend position of clamping arms on CNC machining centers during initial setup or tooling offsets, utilizing the 0 to 90 mm travel window.
Product Changeover Guides
Rapidly reconfigure diverter positions on packaging lines when switching carton sizes, using the external stop rather than installing physical shims.
Press Trial Positions
Test varying pressing depths on assembly equipment by adjusting the extend limit on the fly, ensuring the 2513.2 N force is applied at the exact required point.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-100SB the Right Cylinder?
When sizing this actuator, consider the 63 mm bore offering a push force of 1558.6 N at 0.5 MPa, or the 100 mm bore providing 3927.0 N. Select this 80 mm model when your application requires up to 513 kgf maximum push at 1.0 MPa alongside precise extend-position tuning. If your setup never requires stroke adjustments, a fixed-stroke ACQ cylinder will suffice. To order, confirm the 80 mm bore, 90 mm full stroke, 100 mm adjustment window, the -S magnet for sensing, and the -B male M22x1.5 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 ACQJ80X90-100SB FAQ
This 80 mm bore cylinder has a usable extend range of 0-90 mm via a 100 mm adjustment window. It provides a push force of 2513.2 N and a pull force of 2267.8 N at 0.5 MPa, a push of 3518.5 N at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The force is identical to a standard ACQ because the adjuster only changes stroke length, not piston area.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke, allowing on-machine tuning without new parts, while the retract stroke remains unaffected. The cylinder uses a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. The included -S magnet works with reed or electronic solid-state switches, but note that a plain cylinder does not hold its load on air loss without an external rod lock.
