Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-50SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 200mm 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 ACQJ160X200-50SB
The AirTAC ACQJ160X200-50SB is a big-bore JIS compact double-acting cylinder with a 200 mm full stroke. An external M36x2.0 threaded stop and lock nut limits the extend end position. This provides a usable extend range of 150-200 mm. The retract stroke remains completely unaffected. The piston area is unchanged, so output force equals a standard ACQ of this bore.
Delivering 10053.1 N push and 9424.8 N pull at 0.5 MPa, this unit uses a 40 mm piston rod with a male M36x1.5 thread. It features fixed NBR elastomer bumpers at each end rather than adjustable air cushions. The built-in piston magnet works with reed or solid-state switches. Operating pressure spans 0.15-1.0 MPa.

| 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 ACQJ160X200-50SB Is Used
Press Tonnage Setup
Dial in the exact 150-200 mm extend stop on a large press to accommodate varying material thicknesses without machining new spacers.
Heavy Fixture Changeover
Modify the extend end position rapidly during product changeover on large automated welding lines to adapt to different assembly dimensions.
Palletizing Trial Positions
Establish the ideal end stroke for new package sizes on a heavy palletizer by testing intermediate extend positions safely before finalizing the setup.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-50SB the Right Cylinder?
If 9424.8 N pull at 0.5 MPa is insufficient, the next smaller 140 mm bore yields 7294.8 N, while no larger bore exists in this range. A fixed-stroke ACQ suffices if your end position never requires field tuning. Confirm ordering essentials: 160 mm bore, 200 mm full stroke, 50 mm window, S magnet, and 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 ACQJ160X200-50SB FAQ
The usable extend range is 150-200 mm (200 mm full stroke minus a 50 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.
The external M36x2.0 threaded stop with lock nut limits the extend stroke length only. It does not alter piston area, so force remains identical to a standard ACQ. Fixed elastomer bumpers decelerate the load at stroke ends, and the S magnet works with reed or solid-state switches. Note that a plain cylinder drifts on air loss; use an external rod lock for fail-safe holding.
