Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30S 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 ACQJ80X50-30S
The AirTAC ACQJ80X50-30S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut on the rod-end side. This mechanism limits the extend stroke, allowing you to fine-tune the end position directly on the machine without swapping components. With a full stroke of 50 mm and a 30 mm adjustment window, the usable extend range runs from 20 mm up to 50 mm. The retract stroke remains completely 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. The cylinder uses a PT3/8 port, a 25 mm piston rod, and a female M16x2.0 rod-end thread. It incorporates fixed elastomer bumpers at both ends for end-of-stroke deceleration, and the -S option provides a built-in piston magnet compatible with reed or electronic solid-state switches.

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 ACQJ80X50-30S Is Used
Machining Fixture Clamping
Dial in the exact clamping extension on a CNC machining center when raw part thickness varies, using the external stop to prevent over-travel without reprogramming the machine.
Product Changeover Diverters
Rapidly adapt conveyor sorting gates for different package lengths by turning the adjuster screw to set the new extend endpoint during production line changeovers.
Packaging Press Setup
Establish trial end positions for a sealing or folding press in packaging equipment, tweaking the stroke down to 20 mm to find the optimal contact pressure before locking the nut.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-30S the Right Cylinder?
When sizing this 80 mm bore actuator, consider the 2513.2 N push force at 0.5 MPa. If your application requires less force, stepping down to a 63 mm bore yields 1558.6 N push, whereas moving up to a 100 mm bore provides 3927.0 N. If the exact 50 mm extend position is fixed and never requires variation, a standard ACQ cylinder will suffice. To order this adjustable version correctly, confirm the 80 mm bore, 50 mm full stroke, 30 mm window, the -S magnet for sensing, and the default female 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 ACQJ80X50-30S FAQ
The usable extend range is 20-50 mm (50 mm full stroke minus the 30 mm window). The 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 maximum push is 513 kgf at 1.0 MPa.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke only; the retract stroke is unaffected. The adjuster changes stroke length but not force. End-of-stroke deceleration relies on fixed elastomer bumpers, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
