Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X100-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X100-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 100mm 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 ACQJ125X100-30SB
The AirTAC ACQJ125X100-30SB represents the big-bore JIS compact pneumatic line, engineered for double-acting operation with a single 32mm rod. It incorporates an external M27x2.0 threaded stop secured by a lock nut, permitting operators to fine-tune the extend end position directly on the machinery. This adjustability creates a usable extension range of 70 to 100mm from the 100mm full stroke, while the retract stroke remains completely unaffected.
Because the adjustment mechanism solely limits travel without altering the 125mm piston area, the output force stays identical to a standard ACQ cylinder. You achieve 6135.9N push and 5733.8N pull at 0.5MPa, scaling to 8590.3N push at 0.7MPa, with a maximum push capacity of 1251kgf at 1.0MPa. The unit includes a male M30x1.5 rod end for direct load coupling, a built-in piston magnet (-S) for electronic or reed switch tracking, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.

| 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 | M22×2.5 (F) / M30×1.5 (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 (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5734 N |
| 0.7 MPa | 8590 N | — |
| Max (@1.0 MPa) | 1251 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 ACQJ125X100-30SB Is Used
Press Tonnage Calibration
Dial in the exact 70-100mm extend position during press setup or tonnage calibration without swapping out physical spacers or cylinder hardware.
Large Fixture Changeover
Adapt heavy-duty assembly stations rapidly by turning the external M27x2.0 adjuster to meet new part dimensions during production line changeovers.
Palletizer Stroke Tuning
Modify the extend reach on a palletizer for varying pallet heights, relying on the fixed NBR bumper to absorb the kinetic energy at the adjusted endpoint.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X100-30SB the Right Cylinder?
When sizing this 125mm bore, dropping to the 100mm bore yields 3927.0N push at 0.5MPa, whereas stepping up to the 160mm bore provides 10053.1N push at 0.5MPa. This ACQJ125X100-30SB fits applications requiring 6135.9N thrust alongside variable extend endpoints. If your end position never varies, a fixed-stroke ACQ cylinder suffices. To order, confirm the 125mm bore, 100mm full stroke, 30mm adjust window, the -S magnet, and the -B male M30x1.5 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 ACQJ125X100-30SB FAQ
At 0.5MPa, the push force is 6135.9N and the pull force is 5733.8N. At 0.7MPa, the push force is 8590.3N, and the maximum push force is 1251kgf at 1.0MPa. The usable extend range is 70-100mm, achieved by shortening the 100mm full stroke by up to the 30mm window.
An external M27x2.0 threaded stop with a lock nut mechanically limits the extend stroke, allowing on-machine endpoint tuning. It changes only the stroke length, so the force remains identical to a standard ACQ of the same bore. The cylinder relies on fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions.
