Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-20SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-20SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 75mm 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 ACQJ160X75-20SB
The AirTAC ACQJ160X75-20SB represents the big-bore JIS compact series, engineered for double-acting single-rod operations. It features a 160mm bore and a 75mm full stroke. An external threaded stop with a lock nut restricts the EXTEND end position, yielding a usable forward range of 55 to 75mm. The RETRACT movement remains completely unaffected by this mechanism. Because the piston area stays constant, output force equals a standard ACQ, delivering 10053.1N push and 9424.8N pull at 0.5MPa. This variant includes the -S magnet and -B male rod-end (M36x1.5) for direct load coupling.
Built to handle substantial loads up to a 2050kgf maximum push at 1.0MPa, this unit relies on a fixed NBR elastomer bumper at each end for deceleration instead of an adjustable air cushion. For high-energy cycles, adding an external shock absorber is advised. The -S piston magnet interfaces seamlessly with reed or electronic solid-state switches via the integrated body grooves. Note that a plain ACQ-type cylinder will drift on air loss; utilize an external rod lock or pilot-operated check valve for fail-safe load holding.

| Bore size | Ø160 mm |
| Full stroke | 75 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 ACQJ160X75-20SB Is Used
Press Fit Depth Tuning
Dial in exact bearing press depths on heavy assembly lines without machining new spacers, using the external stop to shift the 55-75mm forward limit instantly.
Heavy Stamping Stops
Modify the forming end-position on large metalworking presses during product changeover, relying on the 14074.3N push at 0.7MPa to move substantial tooling.
Large Clamp Positioning
Establish trial clamping endpoints for oversized composite molds, leveraging the 40mm rod and M36x1.5 male thread for rigid, direct load attachment.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X75-20SB the Right Cylinder?
When sizing this unit, stepping down to a 140mm bore lowers the 0.5MPa push to 7696.9N, while moving up to the 160mm bore provides the 10053.1N push required for heavy pressing. If your application never requires altering the end position, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable model correctly, confirm the 160mm bore, 75mm full stroke, 20mm window, -S magnet, and -B male rod thread. The PT3/8 porting and M36x2.0 adjuster thread are fixed by this bore size.
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 ACQJ160X75-20SB FAQ
The usable extend range is 55 to 75mm (a 75mm full stroke shortened by a 20mm window). Force is identical to a standard ACQ: 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 external M36x2.0 threaded stop with lock nut changes only the forward stroke length, leaving the piston area and output force unchanged. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. The -S magnet works with reed or solid-state switches.
