Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-50SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 150mm 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 ACQJ160X150-50SB
The ACQJ160X150-50SB is a double-acting JIS compact cylinder featuring a big-bore 160mm body and an external stroke adjuster. A threaded stop with a lock nut restricts the extend travel, yielding a usable extend range of 100-150mm from the 150mm full stroke. Retract travel remains completely unaffected. Because the piston area is unaltered, output force equals a standard ACQ of this size.
This variant includes the male M36x1.5 rod end (-B) and a piston magnet (-S). It generates 10053.1N push and 9424.8N pull at 0.5MPa, with a maximum push capacity of 2050kgf at 1.0MPa. The unit relies on a fixed NBR elastomer bumper at each end for deceleration rather than adjustable air cushions. Magnetic sensor grooves accept reed or solid-state switches.

| 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 ACQJ160X150-50SB Is Used
Heavy Press Fixturing
Dial in the exact extend end-stop during heavy press setup without machining custom spacers, allowing rapid accommodation of varying workpiece heights.
Large Press Changeover
Switching product lines on a large press line is streamlined by turning the external M36x2.0 adjuster to shorten the extend stroke by up to 50mm for new die positions.
Platen Positioning Trials
Safely test intermediate extend positions on large platens within the 100-150mm usable range before finalizing mechanical hard stops.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X150-50SB the Right Cylinder?
Choosing this 160mm bore provides 10053.1N push at 0.5MPa; dropping to a 140mm bore lowers push to 7696.9N, while no larger bore exists in this range. If your extend end position never varies, a fixed-stroke ACQ cylinder is simpler and sufficient. When ordering, verify the 150mm full stroke, the 50mm adjuster window, the -SB magnet and male thread options, and the PT3/8 port size.
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 ACQJ160X150-50SB FAQ
At 0.5MPa, push force is 10053.1N and pull force is 9424.8N; at 0.7MPa, push is 14074.3N. The maximum push is 2050kgf at 1.0MPa. The full stroke is 150mm, but the external adjuster allows the extend stroke to be shortened by up to 50mm, giving a usable extend range of 100-150mm.
The external M36x2.0 threaded stop with a lock nut limits only the extend length, so force remains identical to a standard ACQ because the piston area is unchanged. The retract stroke is unaffected. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
