Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-20SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-20SB 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 ACQJ160X100-20SB
The AirTAC ACQJ160X100-20SB is a large-bore JIS compact cylinder featuring an external extend-stop mechanism. A threaded adjuster with a lock nut lets you fine-tune the outward stroke from 80 mm up to the full 100 mm directly on your machinery, avoiding parts swapping. The return stroke remains completely unaffected.
Because the piston area stays constant, output force matches a standard ACQ exactly, delivering 10053.1 N push at 0.5 MPa. This SB configuration includes a piston magnet for position sensing and a male M36x1.5 rod end. It relies on fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable pneumatic cushions.

| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-20SB |
|---|---|
| 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 ACQJ160X100-20SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 80 to 100 mm extension on a large stamping press to accommodate different material thicknesses without machining new spacers.
Automotive Welding Fixture
Adjust the clamping reach on the fly during vehicle model changeovers to position heavy welding guns accurately.
Palletizing End Effectors
Tune the push-out distance for varying pallet sizes or box dimensions on a high-capacity robotic loading arm.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-20SB the Right Cylinder?
Selecting this 160 mm bore provides massive thrust in a space-saving format. If you need slightly less power, stepping down to a 140 mm bore yields 7696.9 N push at 0.5 MPa. If your application never requires altering the end position, a fixed-stroke ACQ cylinder is simpler and sufficient. Confirm your ordering requirements carefully: 160 mm bore, 100 mm full stroke, 20 mm adjuster window, plus the S magnet and B male thread options.
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 ACQJ160X100-20SB FAQ
This 160 mm bore cylinder delivers 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 -20 window allows the extend stroke to be shortened by up to 20 mm, giving a usable outward range of 80 to 100 mm.
The M36x2.0 external threaded stop limits only the extend length without altering the piston area, so force remains identical to a standard ACQ. Deceleration relies on fixed NBR bumpers, not adjustable air cushions. Note that a plain compact cylinder will drift if air pressure is lost, so use an external rod lock for fail-safe load holding.
