Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-40SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 200mm 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 ACQJ160X200-40SB
The AirTAC ACQJ160X200-40SB is a double-acting JIS compact cylinder engineered with an external stroke adjuster. An external M36x2.0 threaded stop equipped with a lock nut restricts the forward extension, providing a usable extend range of 160 to 200 mm. The return stroke remains completely unaffected, while the output force stays identical to a standard ACQ counterpart because the piston area is unchanged.
Operating within 0.15-1.0 MPa pressure limits, this big-bore variant yields 10053.1 N push and 9424.8 N pull at 0.5 MPa. It incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The -S magnet enables tracking by either reed or electronic solid-state switches, and the -B option provides an M36x1.5 male rod end for direct load coupling.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ160X200-40SB Is Used
Heavy Press Tooling Changeover
Adapt large stamping presses to new die heights by dialing the extend stop within the 160-200 mm window without machining new spacers.
Large Assembly Fixture Calibration
Micro-adjust the end position of heavy clamping arms on automotive assembly lines to ensure precise bearing seating without swapping cylinders.
Pallet Positioning Stops
Fine-tune the raise height of heavy pallet lifts in packaging conveyors, accommodating varying load dimensions via the external lock nut.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-40SB the Right Cylinder?
When sizing this 160 mm bore actuator, dropping down to an 80 mm bore yields 2513.2 N push at 0.5 MPa, whereas the 160 mm bore provides 10053.1 N. If your machinery never requires end-position tuning, a fixed-stroke ACQ cylinder will suffice. To order this adjustable version correctly, confirm the 200 mm full stroke, the 40 mm adjustment 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 ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-40SB 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 200 mm with a 40 mm window, allowing an extend range of 160-200 mm. The retract stroke remains unaffected.
The external M36x2.0 threaded stop with a lock nut limits the forward extension distance only; it does not change the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed elastomer bumpers, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
