Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-10SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 20mm 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 ACQJ160X20-10SB
The AirTAC ACQJ160X20-10SB is a big-bore JIS compact cylinder engineered for double-acting operation with an external extend-stop mechanism. A threaded adjuster (M36x2.0) and lock nut restrict how far the rod travels outward, providing a usable extension span of 10 to 20 mm from the 20 mm full stroke. The retract distance remains factory-set and unaffected by this adjustment. Featuring a 40 mm piston rod and a male M36x1.5 thread end (-B), it couples directly to heavy loads.
Because the piston face area stays constant, output force equals a standard ACQ of identical bore: 10053.1 N push and 9424.8 N pull at 0.5 MPa, peaking at 2050 kgf under 1.0 MPa. The unit integrates a piston magnet (-S) compatible with reed or solid-state switches, operating at speeds from 30 to 500 mm/s. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions.

| 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 ACQJ160X20-10SB Is Used
Press Tooling Setup
Dial in the exact 10 to 20 mm outward reach during stamping press changeovers without machining custom spacers for varying material thicknesses.
Heavy Material Stops
Regulate the end position of thick steel or composite sheets in a rolling mill, allowing quick 10 mm retraction of the physical stop for product variants.
Clamping Depth Control
Establish precise clamping depth on large automotive welding fixtures, tweaking the outward limit on the machine to prevent part deformation.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X20-10SB the Right Cylinder?
Delivering massive thrust in a compact footprint, this Ø160 bore yields 10053.1 N push at 0.5 MPa, sitting at the top of the range with no larger standard bore available. If this capacity exceeds your requirement, scaling down to a Ø140 bore provides 7696.9 N push force. Choose this adjustable model specifically when your setup demands on-the-fly extension tuning within the 10-20 mm window; otherwise, a fixed-stroke ACQ cylinder is sufficient. Confirm ordering essentials: 160 mm bore, 20 mm full stroke, 10 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 ACQJ160X20-10SB FAQ
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 10 mm window allows the extend stroke to be fine-tuned down from the 20 mm full stroke, yielding a usable extension range of 10 to 20 mm.
An external M36x2.0 threaded screw with a lock nut mechanically limits the outward travel, changing only the stroke length while keeping force identical to a standard ACQ. Fixed NBR bumpers absorb end-of-stroke energy. Note that a plain cylinder does not hold loads on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
