Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-100SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 100mm 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 ACQJ160X100-100SB
The ACQJ160X100-100SB is a double-acting JIS compact cylinder featuring a 160mm bore and a 100mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable forward range of 0 to 100mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays constant, output force equals a standard ACQ of this exact size.
This big-bore variant delivers massive power within a compact riveted body. It includes a male M36x1.5 rod end for direct load coupling, a 40mm piston rod, and PT3/8 ports. The unit relies on fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions. An integrated magnet (-S) enables position sensing with either reed or electronic solid-state switches.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 100 mm |
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ160X100-100SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 0 to 100mm extend position during heavy press commissioning to accommodate varying material thicknesses without machining new spacers.
Automotive Welding Fixture
Adjust the forward stop on the fly for product changeovers between different automotive frame sizes, ensuring precise clamp placement every time.
Large Mold Handling
Fine-tune the end position when lifting and positioning heavy molds, allowing operators to test trial end positions safely before final lock-down.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-100SB the Right Cylinder?
Selecting this 160mm bore provides a push force of 10053.1N at 0.5MPa and 14074.3N at 0.7MPa, with a maximum push capacity of 2050kgf at 1.0MPa. Stepping down to a 140mm bore drops the 0.5MPa push to 7696.9N, while no larger bore exists in this series. If your machine requires a fixed 100mm forward movement with no on-machine variation, a standard ACQ cylinder will suffice. When ordering, confirm the 160mm bore, 100mm full stroke, 100mm 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 ACQJ160X100-100SB FAQ
It delivers a push of 10053.1N and pull of 9424.8N at 0.5MPa, and 14074.3N push at 0.7MPa. The maximum push is 2050kgf at 1.0MPa. The usable extend range is 0-100mm (100mm full stroke minus the 100mm window). The retract stroke is unaffected.
An external M36x2.0 threaded stop with a lock nut mechanically limits the extend length, meaning force is identical to a standard ACQ because piston area is unchanged. Fixed NBR bumpers decelerate the rod near stroke end. A plain compact cylinder does not hold its load on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
