About the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X15-10SB
The AirTAC ACQJ20X15-10SB is a double-acting JIS compact cylinder with an external adjustable extend stop. A threaded rod-end screw with a lock nut lets you trim the extend stroke on the machine, yielding a usable forward range of 5-15 mm. The return stroke remains fixed at 15 mm. Because the piston area stays constant, output force is identical to a standard ACQ of this bore.
Equipped with a male M8x1.25 piston rod end (-B) and a built-in magnet (-S), it integrates directly with loads and magnetic switches. The body uses fixed elastomer bumpers for end-of-stroke deceleration instead of adjustable air cushions. Operating pressure spans 0.15-1.0 MPa, and the M5x0.8 port feeds a 10 mm diameter rod.

| Rod thread | M5×0.8 (F) / M8×1.25 (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 (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 ACQJ20X15-10SB Is Used
Short-Stroke Clamping
Dial in the exact 5-15 mm clamping travel on machining fixtures without swapping out cylinder bodies.
Product Changeover Stops
Reposition the extend limit rapidly on a packaging line when handling different carton heights.
Prototype Positioning
Establish trial end positions for a new pick-and-place assembly by turning the external stopper screw.
Is the Airtac ACQJ12~25 Adjustable Compact Cylinder ACQJ20X15-10SB the Right Cylinder?
When sizing this 20 mm bore, it delivers 157.1 N push and 117.8 N pull at 0.5 MPa. Stepping down to a 16 mm bore drops push to 100.5 N, while moving up to a 25 mm bore raises it to 245.4 N. If your application never requires end-position adjustments, a fixed-stroke ACQ20 cylinder is simpler and sufficient. To order, confirm the 20 mm bore, 15 mm full stroke, 10 mm adjuster window, the -S magnet, and the -B male 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 ACQJ12~25 Adjustable Compact Cylinder ACQJ20X15-10SB FAQ
It provides 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 15 mm with a 10 mm adjustment window, allowing a usable extend range of 5-15 mm.
The external M8x1.25 threaded stop with a lock nut limits only the extend length, leaving the retract stroke unaffected. It changes stroke length only, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, and the -S magnet works with reed or solid-state switches.
