Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-30S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 125mm 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 ACQJ160X125-30S
The AirTAC ACQJ160X125-30S is a double-acting, single-rod JIS compact cylinder engineered for big-bore applications up to 300 mm standard stroke. It features an external threaded stop with a lock nut on the rod-end side, allowing operators to limit how far the rod extends. With a 125 mm full stroke and a 30 mm adjustment window, the usable extend range spans 95 to 125 mm. The retract stroke remains completely unaffected by this mechanism. A built-in piston magnet (-S) is included, compatible with both reed and electronic solid-state magnetic switches.
Because the adjuster only alters travel length and not the piston area, the output force is identical to a standard ACQ of this bore. At 0.5 MPa, it delivers 10053.1 N of push force and 9424.8 N of pull force. The unit incorporates a fixed elastomer NBR bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, and the body uses a PT3/8 port alongside a 40 mm rod.

| 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 ACQJ160X125-30S Is Used
Heavy Press Tonnage Calibration
Dial in the exact 95-125 mm extend position during heavy press setup without machining new spacers or swapping cylinders.
Large Assembly Fixture Stops
Adapt end positions rapidly on the factory floor when changing between heavy product variants on a single welding fixture.
Palletizing Height Changes
Fine-tune the extend stroke on automated palletizers to accommodate different pallet heights while maintaining 10053.1 N push force.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X125-30S the Right Cylinder?
When sizing this 160 mm bore variant, stepping down to a 140 mm bore drops the 0.5 MPa push force to 7696.9 N, while stepping up to this model yields 10053.1 N. If your application never requires varying the extend end position, a standard fixed-stroke ACQ cylinder will suffice. If you need on-machine tuning for product changeovers, specify the bore (160 mm), full stroke (125 mm), adjustment window (30 mm), the -S magnet, and your required rod thread (default female M24x3.0).
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 ACQJ160X125-30S FAQ
It provides 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 full stroke is 125 mm with a 30 mm window, yielding a usable extend range of 95-125 mm.
The external M36x2.0 threaded stop with lock nut limits the extend travel without changing the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper, not an adjustable air cushion. Note that a plain cylinder does not hold its load on air loss; use an external rod lock for fail-safe holding.
