Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-40SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 50mm 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 ACQJ80X50-40SB
The AirTAC ACQJ80X50-40SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend stroke. You can fine-tune the extend end position on the machine without changing parts. The full stroke is 50 mm, and the -40 mm window allows the usable extend range to be adjusted from 10 mm up to 50 mm. The retract stroke remains unaffected by this adjustment.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 2513.2 N of push force at 0.5 MPa. This model includes the -S magnet for reed or solid-state switches and the -B male piston rod end (M22x1.5) for direct load coupling. It features a fixed elastomer bumper at each end for end-of-stroke deceleration and uses a PT3/8 port.

| 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 ACQJ80X50-40SB Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC lathe fixture during part changeovers without machining new spacer plates.
Carton Sealing Press
Adjust the sealing head descent on the fly to accommodate varying package heights while maintaining full retract travel.
Assembly Machine Stops
Set precise end positions for product indexing on an assembly line, tweaking the 10-50 mm extend range as needed.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-40SB the Right Cylinder?
When sizing this 80 mm bore actuator, consider the adjacent options: a 63 mm bore provides 1558.6 N push at 0.5 MPa, while a 100 mm bore yields 3927.0 N push at 0.5 MPa. If your extend position never varies, a fixed-stroke ACQ cylinder is sufficient and simpler. To order, confirm the 80 mm bore, 50 mm full stroke, 40 mm adjustable window, the S magnet option, and the B male rod thread. Remember that a standard compact cylinder does not hold 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 ACQJ80X50-40SB FAQ
The usable extend range is 10-50 mm (full 50 mm stroke minus the 40 mm window). Force is identical to a standard ACQ: 2513.2 N push and 2267.8 N pull at 0.5 MPa, 3518.5 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The retract stroke is unaffected.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke without altering piston area, so force remains unchanged. The cylinder uses fixed elastomer bumpers at each end, not adjustable air cushions. The included -S magnet works with reed or electronic solid-state switches.
