Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-30SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-30SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm 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 ACQJ160X100-30SB
The ACQJ160X100-30SB is a double-acting JIS compact cylinder featuring a big-bore 160mm piston and a 40mm rod. An external threaded stop with a lock nut restricts the forward extension, allowing you to dial in the end position directly on your machinery. With a 30mm adjustment window, the usable extend range spans 70 to 100mm, while the retract stroke remains completely unaffected.
Because the adjuster solely limits travel, the piston area stays intact, meaning output force is identical to a standard ACQ of this size. You get 10053.1N of push at 0.5MPa. This variant includes a male M36x1.5 rod end for direct load coupling, a built-in magnet for position sensing, and fixed NBR elastomer bumpers at both ends to absorb impact energy.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-30SB Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-30SB |

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø160 mm |
| Full stroke | 100 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 ACQJ160X100-30SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 70-100mm extension on a large stamping press to accommodate varying material thicknesses without machining new spacer blocks.
Large Fixture Changeover
Adjust the forward stop during automated machining line changeovers to position heavy workholding fixtures precisely against a hard stop.
Pallet Lift Height Tuning
Fine-tune the lifting endpoint on heavy-duty palletizing stations to match pallet heights perfectly, relying on the 2050kgf max push capacity.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-30SB the Right Cylinder?
Selecting this 160mm bore unit provides massive thrust, delivering 14074.3N at 0.7MPa. If your application requires less force, stepping down to a 140mm bore yields 7696.9N of push at 0.5MPa; conversely, the 160mm is the largest big-bore compact option available with standard strokes up to 300mm. If you never need to alter the forward endpoint, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 100mm full stroke, the 30mm window, the male rod thread, and the required magnet option.
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 ACQJ160X100-30SB FAQ
This model delivers 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 full stroke is 100mm, and with the 30mm window, the usable extend range is 70-100mm.
The M36x2.0 external threaded stop limits only the extend length, leaving retract untouched and keeping force identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. Note that this cylinder will drift if air pressure is lost; use an external rod lock for fail-safe load holding.
