Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-40SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 300mm 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 ACQJ160X300-40SB
The AirTAC ACQJ160X300-40SB is a double-acting JIS compact cylinder featuring an external extend-stop mechanism. A threaded rod-end stop with a lock nut lets you fine-tune the extend end position on the machine, yielding a usable extend range of 260 to 300 mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore.
This big-bore unit delivers 10053.1 N push force at 0.5 MPa and accepts up to 1.0 MPa operating pressure. It includes a male M36x1.5 piston rod end for direct load coupling and a built-in magnet for position sensing. Fixed NBR elastomer bumpers at each end decelerate the motion, while the PT3/8 port supplies the air. The external adjuster utilizes an M36x2.0 thread.

| 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 |

| 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 ACQJ160X300-40SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 260 to 300 mm extend position during press tooling trials without machining custom spacers.
Large Injection Mold Changeover
Adapt the clamp stroke rapidly when switching between deep and shallow mold sets on large injection molding machines.
Bulk Pallet Positioning
Adjust the final lower position on the fly to accommodate varying pallet heights or product stack depths in packaging lines.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X300-40SB the Right Cylinder?
Choosing this 160 mm bore provides 10053.1 N of push force at 0.5 MPa. Stepping down to a 140 mm bore yields 7696.9 N, whereas moving up is not applicable as this is the largest available diameter. If your application never requires end-position tuning, a fixed-stroke ACQ cylinder is sufficient. Confirm your ordering essentials: 160 mm bore, 300 mm full stroke, 40 mm 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 ACQJ160X300-40SB FAQ
The usable extend range is 260 to 300 mm (300 mm full stroke minus a 40 mm window). It 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 port size is PT3/8.
An external M36x2.0 threaded stop and lock nut limits the extend stroke length only, so the force remains identical to a standard ACQ. Fixed NBR bumpers decelerate the motion near stroke end. A plain ACQ-type does not hold its load on air loss, so for a fail-safe hold you must add an external rod lock or pilot-operated check valve.
