Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 90mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50S
The AirTAC ACQJ32X90-50S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You get a usable extend range of 40-90 mm from the 90 mm full stroke, tunable directly on the machine without swapping parts. The retract stroke remains completely unaffected.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore: 402.1 N push and 301.6 N pull at 0.5 MPa. The 32 mm bore uses a PT1/8 port, a 16 mm rod, and fixed NBR elastomer bumpers at both ends. The built-in magnet (-S) supports reed or electronic solid-state switches.

| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Rod thread | M8×1.25 (F) / M14×1.5 (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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50S Is Used
Machining Fixture Stops
Dial in the extend position from 40 to 90 mm on CNC machining fixtures to accommodate raw part tolerances without fabricating new stop collars.
Packaging Changeover
Adjust the extend endpoint rapidly during packaging line format changeovers to handle different carton depths on the fly.
Prototype Positioning
Trial different extend end positions on lab automation rigs to find the optimal engagement distance before finalizing a machine design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50S the Right Cylinder?
If you need less push, the 25 mm bore yields 245.4 N at 0.5 MPa, while stepping up to a 40 mm bore provides 628.3 N. Choose this 32 mm model when your setup requires exactly 402.1 N of push force alongside variable extend positioning. If the end position never changes, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 90 mm full stroke, 50 mm window, S magnet, and female M8x1.25 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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-50S FAQ
It delivers 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The 90 mm full stroke has a 50 mm window, allowing an adjustable extend range of 40-90 mm.
An M12x1.25 threaded adjuster with a lock nut mechanically limits the extend length, leaving retract unchanged. Force remains identical to a standard ACQ because piston area is unaltered. The cylinder uses fixed elastomer bumpers, not a locking mechanism, so an external rod lock is required for fail-safe load holding on air loss.
