Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 125mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100SB
The AirTAC ACQJ160X125-100SB is a double-acting, single-rod JIS compact cylinder built for big-bore applications, featuring an external threaded stop with a lock nut that permits on-site extend-travel tuning. With a 125 mm full stroke and a 100 mm adjustment window, the usable extend range spans 25 to 125 mm, while the retract stroke remains completely unaffected. It includes a male piston rod end (M36x1.5) for direct load coupling and a built-in piston magnet (-S) compatible with reed or solid-state electronic switches.
Because the adjuster limits travel length only, the piston area stays the same, meaning force is identical to a standard ACQ of this size. At 0.5 MPa it generates 10053.1 N of push force and 9424.8 N of pull force, reaching 14074.3 N push at 0.7 MPa and a maximum of 2050 kgf at 1.0 MPa. The unit uses a PT3/8 port, a fixed NBR elastomer bumper at each end for end-stop deceleration, and an M36x2.0 external adjuster thread.

| Adjuster thread | M36×2.0 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| Rod thread | M24×3.0 (F) / M36×1.5 (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 (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 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 ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 25 to 125 mm extend position on a large metal-stamping press during initial tooling setup, preventing over-travel without machining new spacers.
Automotive Welding Line Changeover
Quickly reposition the extend stop for different chassis fixture heights during vehicle model changeovers, using the external M36x2.0 adjuster to save setup time.
Large-Format Pallet Stops
Fine-tune the end position for varying pallet dimensions on a heavy-duty packaging conveyor, relying on the 10053.1 N push force to halt large loads securely.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100SB the Right Cylinder?
If 9424.8 N pull at 0.5 MPa is insufficient, verify if a fixed-stroke ACQ might suffice, but if adjustable end-positioning is required, this model is ideal. For slightly lower force demands, the neighboring 140 mm bore provides 7696.9 N push at 0.5 MPa. Since this is the largest bore in the compact range (up to 300 mm standard stroke), there is no larger ACQJ size. When ordering, confirm the 160 mm bore, 125 mm full stroke, 100 mm window, the -S magnet, and the -B male rod thread. Note that a plain ACQ-type cylinder does not hold its load on air loss; for fail-safe holding, specify an external rod lock or pilot-operated check valve.
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 ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-100SB FAQ
It provides 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 125 mm with a 100 mm window, allowing a usable extend range of 25 to 125 mm. The retract stroke remains unaffected.
No, the external threaded stop only limits how far the rod extends, so force is identical to a standard ACQ of the same bore. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. For high-speed or high-energy loads, add an external shock absorber or slow the approach.
