Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10B
The AirTAC Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø20mm bore and 35mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10B
The AirTAC ACQJ20X35-10B is a double-acting JIS compact cylinder featuring a male-thread piston rod end (M8x1.25) that couples directly to your load. An external adjuster screw with a lock nut limits the extend travel, allowing you to fine-tune the end position on the machine without swapping parts. The usable extend range is 25-35 mm, while the retract stroke remains unaffected.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore: 157.1 N push and 117.8 N pull at 0.5 MPa. The unit operates at 30-500 mm/s and relies on fixed elastomer TPU bumpers at each end for deceleration rather than adjustable air cushions. The body includes sensor grooves, though this specific configuration ships without a magnet.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10B Is Used
Machine Takedown Stops
Dial in the exact extend end position during equipment setup or fixture changes without machining new spacers.
Carton Flap Folding
Adjust the extend stroke on the fly to accommodate varying package heights and folding requirements.
Press Trial Positions
Safely test different end-of-stroke contact points on a press line before locking the lock nut.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10B the Right Cylinder?
If you need less force, the bore 16 variant provides 100.5 N push at 0.5 MPa, while the larger bore 25 option delivers 245.4 N for heavier demands. A fixed-stroke ACQ cylinder is sufficient if your end position never requires adjustment. When ordering, confirm the 20 mm bore, 35 mm full stroke, 10 mm window, male rod thread, and whether you need the -S magnet option for reed or solid-state switches.
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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X35-10B FAQ
It delivers 157.1 N push and 117.8 N pull at 0.5 MPa, 219.9 N push at 0.7 MPa, and a maximum push of 32 kgf at 1.0 MPa. The full stroke is 35 mm, and the external M8x1.25 adjuster allows the extend stroke to be shortened by up to 10 mm, giving a usable extend range of 25-35 mm.
No, the adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for end-of-stroke deceleration. It will not hold a load on air loss, so an external rod lock is needed for fail-safe holding.
