Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 50mm 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 ACQJ160X50-10SB
The AirTAC ACQJ160X50-10SB represents the big-bore JIS compact adjustable-stroke family, engineered for double-acting single-rod operations. An external threaded stop paired with a lock nut restricts the extend end position, delivering a usable forward range of 40-50mm (the 50mm full stroke minus up to 10mm). The retract movement remains entirely unaffected by this mechanism. A male M36x1.5 piston rod end (-B) couples directly to your load, while the integrated magnet (-S) tracks position.
Because the internal piston area stays constant, output force is identical to a standard ACQ of this size: 10053.1N push and 9424.8N pull at 0.5MPa. The cylinder relies on a fixed NBR elastomer bumper at each end for end-of-travel deceleration rather than an adjustable air cushion. Operating pressure spans 0.15-1.0MPa, and the body accepts PT3/8 ports.

| 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 ACQJ160X50-10SB Is Used
Press Tooling Setup
Dial in the exact 40-50mm extend position during press tooling changes without machining new spacers, using the M36x2.0 external adjuster to set the precise stroke.
Heavy Stamping Stops
Accommodate varying material thicknesses on a heavy stamping line by turning the extend stop out slightly, maintaining the full 10053.1N force at 0.5MPa.
Large Pallet Forming
Test different folding end-positions on a large pallet forming machine, relying on the fixed NBR bumper to absorb the energy of this high-thrust cylinder.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X50-10SB the Right Cylinder?
Choosing this Ø160 bore provides immense thrust, pushing 10053.1N at 0.5MPa (up to 2050kgf at 1.0MPa). If your application requires less force, stepping down to a Ø140 bore yields 7696.9N push at 0.5MPa; conversely, this is the largest standard big-bore compact option available. A fixed-stroke ACQ cylinder is sufficient if your end-stop never requires field adjustments. When ordering, verify the 50mm full stroke, the 10mm adjuster window, the -S magnet, and the -B male rod thread. Note that a plain compact cylinder drifts on air loss, so deploy an external rod lock for fail-safe holding.
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 ACQJ160X50-10SB FAQ
It 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 50mm, but the external adjuster provides a usable extend range of 40-50mm (a 10mm window), while the retract stroke remains fixed.
The external M36x2.0 threaded stop with a lock nut mechanically limits how far the rod extends, shortening the forward stroke without changing the piston area, so force stays identical to a standard ACQ. Deceleration is handled by a fixed elastomer bumper, not an adjustable air cushion. The built-in -S magnet is compatible with both reed and electronic solid-state switches.
