Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-40B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-40B 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 ACQJ80X90-40B
The AirTAC ACQJ80X90-40B is a double-acting JIS compact cylinder featuring an external M20x1.5 threaded stop with a lock nut that restricts the outward rod travel. You can fine-tune the extend position on the machine anywhere from 50 mm up to the full 90 mm, while the retract distance remains completely unaffected. This model includes a male M22x1.5 piston rod end for direct load coupling.
Because the internal piston area stays constant, the output force is identical to a standard ACQ of the same bore: 2513.2 N push and 2267.8 N pull at 0.5 MPa. The body uses fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions, and it operates at speeds between 30 and 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 ACQJ80X90-40B Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC lathe during product changeovers by turning the external stop screw, avoiding the need to fabricate custom spacer rings.
Carton Sealing Tampers
Adjust the flap-tamping depth on packaging lines for varying box heights, setting the outward stroke anywhere from 50 to 90 mm while maintaining full retract distance.
Press Ejector Setup
Regulate the parts-ejection length on a mechanical press to test trial end positions safely before finalizing the mechanical hard stop.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-40B the Right Cylinder?
If you need slightly less thrust, the adjacent 63 mm bore yields 1558.6 N push at 0.5 MPa, whereas stepping up to the 100 mm bore provides 3927.0 N push. Choose this 80 mm bore if your application demands up to 513 kgf maximum push force at 1.0 MPa alongside precise outward-stop tuning. When you do not require on-machine stroke shortening, a fixed-stroke ACQ cylinder suffices. To order, confirm the 80 mm bore, 90 mm full stroke, 40 mm adjustment window, the male rod thread (-B), and whether a magnet (-S) is needed for sensor grooves.
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 ACQJ80X90-40B FAQ
At 0.5 MPa it provides 2513.2 N push and 2267.8 N pull; at 0.7 MPa push is 3518.5 N. The maximum push force is 513 kgf at 1.0 MPa. The usable extend range is 50-90 mm (a 40 mm window subtracted from the 90 mm full stroke).
The M20x1.5 threaded stop alters only the extend length, leaving the piston area and therefore the thrust unchanged from a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions. This unit ships without a magnet (-S omitted), though the body retains sensor grooves for adding reed or solid-state switches separately.
