Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-50SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-50SB 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 ACQJ160X100-50SB
The AirTAC ACQJ160X100-50SB is a double-acting JIS compact cylinder featuring an external extend stop. A threaded adjuster with a lock nut lets you set the outward stroke anywhere between 50 and 100 mm. The return stroke remains fixed at its full length. Because the piston diameter is unchanged, output force equals a standard ACQ of this bore.
This big-bore variant uses a 40 mm piston rod and a PT3/8 port. It includes a male M36x1.5 rod-end thread for direct coupling and a built-in magnet for position sensing. Fixed NBR elastomer bumpers absorb impact at both ends, and the body supports standard strokes up to 300 mm.

| 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 ACQJ160X100-50SB Is Used
Heavy Press Tonnage Setup
Dial in the exact 50 to 100 mm extend reach during a press tooling changeover without machining new spacers.
Large Extruder Cutoff
Adjust the stroke length on the floor to fine-tune the shear position for varying aluminum profile widths.
Pallet Lift Positioning
Set precise end stops for lifting different pallet heights, relying on the fixed bumper for end-of-travel deceleration.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-50SB the Right Cylinder?
This 160 mm bore generates 10053.1 N push at 0.5 MPa. Stepping down to a 140 mm bore yields 7696.9 N push, while no larger bore exists in this range. If your machine never requires altering the end position, a fixed-stroke ACQ cylinder suffices. When ordering, confirm the 100 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 ACQJ160X100-50SB 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 100 mm with a 50 mm window, giving a usable extend range of 50-100 mm.
The external M36x2.0 threaded stop with lock nut limits the extend length without changing the piston area, so force remains identical to a standard ACQ. It uses fixed elastomer bumpers rather than adjustable air cushions. Note that a plain cylinder drifts on air loss; use an external rod lock for fail-safe holding.
