Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X100-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X100-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm 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 ACQJ125X100-10S
The AirTAC ACQJ125X100-10S is a double-acting JIS compact cylinder with a 125mm bore and a 100mm full stroke. An external M27x2.0 threaded stop equipped with a lock nut limits the extend end position. This provides a usable extend range of 90-100mm, allowing you to shorten the outward stroke by up to 10mm directly on the machine. The retract stroke remains unaffected.
Because the piston area is unchanged, the adjuster modifies stroke length only, meaning the force output is identical to a standard ACQ of this bore. At 0.5 MPa, it delivers 6135.9N of push force and 5733.8N of pull force. The unit includes a built-in piston magnet compatible with reed or solid-state switches, and relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X100-10S Technical Specifications
| Model | Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X100-10S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø125 mm |
| Full stroke | 100 mm |
| Adjuster thread | M27×2.0 |
| 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 | M22×2.5 (F) / M30×1.5 (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 (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 6136 N | 5734 N |
| 0.7 MPa | 8590 N | — |
| Max (@1.0 MPa) | 1251 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 ACQJ125X100-10S Is Used
Press Fit Depth Tuning
Dial in exact insertion depths for bearing or bushing press operations without machining new hard stops, using the 90-100mm extend range to accommodate material variances.
Automated Pallet Changeover
Adjust the extend stop on packaging machinery to handle different pallet or container sizes on the fly, ensuring accurate positioning without lengthy mechanical reconfiguration.
Robotic Gripper Calibration
Fine-tune the outward reach of a large end-effector or gripper during initial machine setup, testing various end positions to find the optimal motion profile before final lockdown.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X100-10S the Right Cylinder?
For applications needing 6135.9N push at 0.5MPa, this 125mm bore big-bore compact cylinder fits perfectly. If slightly less force is acceptable, the 100mm bore variant provides 3927.0N push, while stepping up to the 140mm bore yields 7696.9N. Choose this adjustable model when setups require trial end positions or product-changeover stops; otherwise, a fixed-stroke ACQ suffices. When ordering, confirm the 125mm bore, 100mm full stroke, 10mm window, the S magnet option, and the default female M22x2.5 rod end 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 ACQJ125X100-10S FAQ
This model has a 125mm bore and a 100mm full stroke with a 10mm adjustable extend window, giving a usable extend range of 90-100mm. The force is identical to a standard ACQ: 6135.9N push and 5733.8N pull at 0.5 MPa, 8590.3N push at 0.7 MPa, and a maximum push of 1251 kgf at 1.0 MPa.
The external M27x2.0 threaded stop with a lock nut mechanically limits the extend stroke length without altering the piston area, so force remains unchanged. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions. The included S magnet works with reed or electronic solid-state switches for position sensing.
