Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-100SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 175mm 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 ACQJ160X175-100SB
The AirTAC ACQJ160X175-100SB is a double-acting, single-rod JIS compact cylinder from the big-bore range, featuring a 160mm bore and 175mm full stroke. It includes a male M36x1.5 rod end (-B) and a piston magnet (-S) for position sensing. An external M36x2.0 threaded stop with a lock nut limits the extend stroke, yielding a usable extension range of 75-175mm. The retract stroke remains completely unaffected by this adjustment.
Because the adjustment mechanism only restricts rod travel, the piston area is unaltered. Consequently, output force is identical to a standard ACQ of this bore: 10053.1N push and 9424.8N pull at 0.5MPa. The unit relies on fixed NBR elastomer bumpers at each end for deceleration rather than adjustable air cushions, and operates at speeds of 30-500mm/s.

| 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 ACQJ160X175-100SB Is Used
Heavy Press Tooling Changeover
Switching press dies in automotive lines requires varying extended end stops to accommodate different material thicknesses without machining new spacers.
Large Assembly Fixture Positioning
Heavy-duty assembly stations use the external M36x2.0 adjuster to dial in the exact 75 to 175mm clamping reach during initial equipment setup.
Palletizer Platen Height Trials
Testing different pallet heights on a packaging line is simplified by turning the lock nut to test new extended end positions rapidly on the floor.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-100SB the Right Cylinder?
Choosing this 160mm bore yields a 2050kgf maximum push at 1.0MPa. Stepping down to the 140mm variant drops the 0.5MPa push to 7696.9N, while stepping up is unavailable in this compact family. If your machine never requires end-position tuning, a fixed-stroke ACQ cylinder provides the same holding force in a simpler package. When ordering this adjustable version, confirm the 175mm full stroke, the 100mm window, the -S magnet for electronic or reed switches, and the -B male 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 ACQJ125~160 Adjustable Compact Cylinder ACQJ160X175-100SB FAQ
It delivers 10053.1N push and 9424.8N pull at 0.5MPa, 14074.3N push at 0.7MPa, and a maximum push of 2050kgf at 1.0MPa. The full stroke is 175mm, but the external adjuster provides a 100mm window, creating a usable extend range of 75-175mm.
The external M36x2.0 threaded stop with lock nut limits only the extend stroke; force remains unchanged because piston area is constant. The cylinder uses fixed NBR elastomer bumpers, not adjustable air cushions. For fail-safe load holding on air loss, an external rod lock or pilot-operated check valve is required, as the rod will drift if valve pressure is lost.
