Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50B 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 ACQJ80X90-50B
The AirTAC ACQJ80X90-50B 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 stroke anywhere from 40 mm up to the full 90 mm directly on your machine, shortening the forward travel by up to 50 mm without swapping parts. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force equals a standard ACQ of the same bore, delivering 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit uses a 25 mm piston rod with a male M22x1.5 thread end for direct load coupling. It includes fixed elastomer NBR bumpers at both ends for end-of-stroke deceleration and operates at speeds between 30 and 500 mm/s.

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 ACQJ80X90-50B Is Used
Machining Fixture Stops
Dial in the exact extend position of a 25 mm rod during product-changeover on a machining line, adjusting the end stop from 40 to 90 mm to accommodate different part thicknesses without disassembling the tooling.
Carton Sealing Plungers
Set the precise downward extend depth for a packaging flap folder, using the external M20x1.5 adjuster to tune the 40-90 mm stroke window while the fixed elastomer bumper absorbs the final impact.
Assembly Press Positioning
Establish trial end positions for a 513 kgf press operation, relying on the unchanged 2513.2 N push force at 0.5 MPa to seat components securely before locking the nut for production runs.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50B the Right Cylinder?
Selecting this 80 mm bore provides 2513.2 N push force at 0.5 MPa, sitting between the 63 mm bore (1558.6 N) and the 100 mm bore (3927.0 N). If your application requires a fixed 90 mm stroke without on-site end-position tuning, a standard ACQ80X90 cylinder is sufficient. When ordering, confirm the 80 mm bore, 90 mm full stroke, 50 mm adjuster window, the male M22x1.5 rod thread, and note that this configuration ships without a sensor magnet.
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 ACQJ80X90-50B FAQ
It delivers 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 usable extend range is 40-90 mm, created by a 50 mm adjustment window on the 90 mm full stroke.
The external M20x1.5 threaded stop with lock nut limits the extend stroke length only; it does not alter piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected, and fixed NBR bumpers decelerate the load at both ends, though an external rod lock is required for fail-safe holding on air loss.
