Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-100S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø125mm bore and 200mm 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 ACQJ125X200-100S
The AirTAC ACQJ125X200-100S is a double-acting, single-rod big-bore compact cylinder featuring an external extend-stop mechanism. An external threaded adjuster with a lock nut limits the outward travel, yielding a usable extend range of 100-200 mm from the 200 mm full stroke. The retract distance remains completely unaffected by this adjustment. Operating pressure spans 0.15-1.0 MPa, and the unit integrates fixed NBR elastomer bumpers at each end for end-of-stroke deceleration.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore: 6135.9 N push and 5733.8 N pull at 0.5 MPa. The -S suffix indicates a built-in piston magnet compatible with both reed and solid-state electronic switches via the cylinder's sensor grooves. This model features a 32 mm rod, PT3/8 ports, and an M27x2.0 external adjuster thread.

| Bore size | Ø125 mm |
| Full stroke | 200 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 |

| 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 ACQJ125X200-100S Is Used
Press Tonnage Calibration
Dial in the exact extend stop on a hydraulic press frame during tonnage calibration, allowing 100 mm of fine-tuning without machining custom spacers.
Heavy Stamping Changeovers
Accommodate varying material thicknesses on a heavy stamping line by turning the external M27x2.0 adjuster to shift the end position for product changeovers.
Large Weldment Positioning
Establish trial end positions for large weldment clamps, tweaking the 100-200 mm usable range on the machine to find the optimal joint alignment.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-100S the Right Cylinder?
For lower force requirements, the ACQJ100 bore provides 3927.0 N push at 0.5 MPa, whereas this Ø125 unit delivers 6135.9 N. If your application requires the full 200 mm extend stroke without variation, a fixed-stroke ACQ cylinder suffices. When ordering, verify the 125 mm bore, 200 mm full stroke, 100 mm adjustable window, -S magnet option, and 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 ACQJ125X200-100S FAQ
The usable extend range is 100-200 mm (a 100 mm window off the 200 mm full stroke). Force matches a standard ACQ: 6135.9 N push and 5733.8 N pull at 0.5 MPa, 8590.3 N push at 0.7 MPa, with a maximum push of 1251 kgf at 1.0 MPa.
No, the external threaded stop only shortens the extend stroke length; it does not change the piston area or force. Deceleration relies on fixed NBR elastomer bumpers at each end, not an adjustable air cushion. For high-speed loads, use an external shock absorber.
