Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10S 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 ACQJ125X200-10S
The AirTAC ACQJ125X200-10S is a double-acting, single-rod JIS compact cylinder engineered for big-bore tasks up to 300 mm standard stroke. An external M27x2.0 threaded stop and lock nut restricts the forward extension, yielding a usable extend range of 190-200 mm. The return stroke remains completely unaffected by this mechanism.
Output force stays identical to a standard ACQ of this size because the piston area is unchanged. Operating pressure spans 0.15-1.0 MPa, generating 6135.9 N push at 0.5 MPa. The body incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| 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 |
| 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 ACQJ125X200-10S Is Used
Heavy Press Tonnage Setup
Dial in the exact 190-200 mm extension on a large stamping press during initial tool setup, avoiding custom spacer machining.
Automotive Fixture Changeover
Adapt clamping depth rapidly on machining lines when switching between vehicle chassis models without swapping the entire actuator.
Pallet Lift Positioning
Fine-tune the raise height of heavy pallet lifting stations to accommodate varying load heights on the fly.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ125X200-10S the Right Cylinder?
Choosing this 125 mm bore provides 6135.9 N push and 5733.8 N pull at 0.5 MPa. Stepping down to a 100 mm bore drops the push to 3927.0 N, while scaling up to a 140 mm bore raises it to 7696.9 N. If your application never requires end-position tweaks, a fixed-stroke ACQ cylinder delivers the exact same power. When ordering, verify the 200 mm full stroke, 10 mm window, PT3/8 porting, M22x2.5 female rod end, and the -S magnet for sensing.
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 ACQJ125X200-10S FAQ
It delivers 6135.9 N push and 5733.8 N pull at 0.5 MPa, 8590.3 N push at 0.7 MPa, and a maximum push of 1251 kgf at 1.0 MPa. The full stroke is 200 mm with a 10 mm adjustable window, giving a usable extend range of 190-200 mm.
An external M27x2.0 threaded screw with a lock nut limits the forward stroke length only; force is unchanged. The cylinder uses fixed elastomer bumpers, not adjustable air cushions. Note that a standard compact cylinder does not hold its load on air loss, so an external rod lock or pilot-operated check valve is required for fail-safe holding.
