Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-20SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-20SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 20mm 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 ACQJ160X20-20SB
The AirTAC ACQJ160X20-20SB is a double-acting, single-rod JIS compact cylinder from the big-bore range, featuring a 160mm bore and 20mm full stroke. It uses an external threaded stop with a lock nut to limit the extend end position, providing a usable forward range of 0-20mm. The retract stroke remains completely unaffected by this mechanism. Because the piston area is unchanged, the output force is identical to a standard ACQ of this size, delivering 10053.1N push and 9424.8N pull at 0.5 MPa.
Equipped with a male M36x1.5 piston rod end (-B) for direct load coupling and a built-in magnet (-S), it supports both reed and electronic solid-state switches. The design incorporates fixed NBR elastomer bumpers at each end rather than adjustable air cushions. Operating pressure spans 0.15-1.0 MPa, and the external adjuster utilizes an M36x2.0 thread for precise on-machine end-position tuning.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 20 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 ACQJ160X20-20SB Is Used
Heavy Press Tuning
Dial in the exact 0-20mm contact position during heavy stamping setup without machining custom spacer blocks.
Product Changeover Stops
Adjust the extend end stop on a packaging line to accommodate varying package heights instantly.
Prototype End Positions
Test trial end positions on a new metal-forming press by fine-tuning the external threaded stop on the fly.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-20SB the Right Cylinder?
When sizing this big-bore 160mm unit against neighboring bores, the 140mm variant yields 7696.9N push while the 160mm provides 10053.1N at 0.5 MPa, offering a distinct step up in thrust for heavy pressing. If your fixture requires a fixed 20mm forward travel with no on-site variance, a standard ACQ cylinder will suffice. To order, confirm the 160mm bore, 20mm full stroke, 20mm adjuster window, the -S magnet for sensor compatibility, and the -B male rod thread.
Quick checklist

- ✓ 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 ACQJ160X20-20SB FAQ
The usable extend range is 0-20mm (20mm full stroke minus the 20mm window), while the retract stroke is unaffected. Force is identical to a standard ACQ: 10053.1N push and 9424.8N pull at 0.5 MPa, 14074.3N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa.
An external M36x2.0 threaded stop with a lock nut limits the extend travel without altering the piston area, ensuring force remains constant. Deceleration is handled by fixed NBR elastomer bumpers at each end, not adjustable air cushions. Note that a plain ACQ does not hold its load on air loss; use an external rod lock for fail-safe holding.
