Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-100SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 250mm 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 ACQJ160X250-100SB
The AirTAC ACQJ160X250-100SB is a big-bore JIS compact, double-acting single-rod cylinder featuring an external extend stop. An external M36x2.0 threaded adjuster with a lock nut lets you set the extend end position anywhere from 150mm up to the full 250mm. The retract stroke remains completely unaffected by this mechanism. Because the piston area stays constant, output force is identical to a standard ACQ of this bore.
At 0.5 MPa, this Ø160mm unit generates 10053.1N of push force and 9424.8N of pull force, peaking at 2050 kgf maximum push under 1.0 MPa. It includes a male M36x1.5 rod end for direct load coupling, fixed NBR elastomer bumpers for end-of-stroke deceleration, and an integrated piston magnet. This magnet is fully compatible with both reed and electronic solid-state switches, sliding directly into the body grooves.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-100SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-100SB |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 250 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 ACQJ160X250-100SB Is Used
Press Tooling Changeover
Adapt pressing depth rapidly during die swaps on a heavy stamping line without machining custom spacers.
Heavy Material Diverter
Tune the gate extension on a bulk palletizer to handle varying package widths on the fly.
Platen Leveling
Dial in exact clamping endpoints for an injection mold platen during initial setup and trial runs.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X250-100SB the Right Cylinder?
When sizing this big-bore unit, consider the adjacent bores: the Ø140 yields 7696.9N push while the Ø160 provides 10053.1N at 0.5 MPa. If your extend endpoint never varies, a fixed-stroke ACQ is simpler and sufficient. For trial positions or product changeovers, this adjustable model saves time. Confirm your ordering essentials: 160mm bore, 250mm full stroke, 100mm adjust window, S magnet, and B male rod thread. Note that a plain compact cylinder drifts on air loss; for fail-safe holding, add an external rod lock.
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 ACQJ160X250-100SB FAQ
It delivers 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. The full stroke is 250mm, but the external stop provides a usable extend range of 150-250mm (a 100mm window).
No. The adjuster only limits how far the rod extends; the piston area is unchanged so force remains identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions, so add an external shock absorber for high-energy loads.
