Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-30B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 50mm 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 ACQJ32X50-30B
The AirTAC ACQJ32X50-30B is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend stroke on the machine from 20 mm up to the full 50 mm without changing parts, while the retract stroke remains unaffected. It features a 32 mm bore, a PT1/8 port, and a male M14x1.5 rod end that couples directly to your load.
Because the adjuster only changes stroke length and not the piston area, the output force stays identical to a standard ACQ of this bore. This model delivers 402.1 N push and 301.6 N pull at 0.5 MPa, with a maximum push capacity of 82 kgf at 1.0 MPa. It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than an adjustable air cushion.

| 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 ACQJ32X50-30B Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC machining center during setup, accommodating varying part heights without machining custom spacers.
Packaging Product Changeover
Rapidly adjust the extend end position on a packaging line when switching between different carton sizes, using the external stop to set new reject or pusher limits.
Assembly Press Stops
Establish trial end positions for pressing operations on an automated assembly line, allowing operators to tweak the 20 to 50 mm extend depth safely before finalizing the cycle.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X50-30B the Right Cylinder?
If you need slightly less thrust, the 25 mm bore yields 245.4 N push at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628.3 N push. This 32 mm bore hits a solid middle ground for mid-range actuation. If your end position never varies, a fixed-stroke ACQ cylinder is simpler and sufficient. When ordering this adjustable variant, confirm the 50 mm full stroke, the 30 mm adjustment window, the male M14x1.5 rod thread, and note this specific SKU ships without a sensor magnet.
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 ACQJ32X50-30B FAQ
This cylinder provides 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 full stroke is 50 mm with a 30 mm adjustment window, giving a usable extend range of 20-50 mm.
The external M12x1.25 threaded stop with lock nut physically limits how far the rod extends, shortening the stroke without altering piston area, so force remains identical to a standard ACQ. It uses fixed elastomer bumpers for deceleration, but because it lacks a rod lock, the cylinder will drift and cannot hold a load if air pressure is lost.
