Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm 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 ACQJ32X80-75SB
The AirTAC ACQJ32X80-75SB is a double-acting JIS compact cylinder featuring a male-thread rod end and an external extend stop. A threaded screw with a lock nut limits how far the piston travels outward, giving you an adjustable usable extend range of 5-80 mm from the 80 mm full stroke. The retract distance remains completely unaffected by this mechanism.
Because the piston area stays constant, output force matches a standard ACQ exactly, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. The 32 mm bore uses a PT1/8 port, a Ø16 mm rod, and fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. An integrated magnet (-S) allows tracking by reed or solid-state switches.

| 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 ACQJ32X80-75SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC machining center during part changeovers without machining new spacer blocks.
Packaging Fold Adjustments
Vary the tucking arm extension depth on a cartoning line to accommodate different box sizes directly at the machine.
Assembly Press Positioning
Establish trial end positions for pressing bearings on an assembly line, safely testing stroke limits before final lockdown.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-75SB 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 a 40 mm bore provides 628.3 N. Choose this 32 mm model when your setup requires roughly 400 N of push force alongside on-the-fly end-position tuning. If the extend position never varies, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable variant, confirm the 32 mm bore, 80 mm full stroke, 75 mm window, the -S magnet, and the -B male M14x1.5 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 ACQJ32X80-75SB FAQ
It 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 75 mm adjustment window allows the extend stroke to be shortened from the 80 mm full stroke down to 5 mm.
An M12x1.25 threaded adjuster with a lock nut mechanically limits the outward stroke length, meaning the force remains identical to a standard ACQ since piston area is unchanged. Deceleration relies on fixed elastomer bumpers rather than adjustable air cushions, so for high-energy cycles you should add an external shock absorber.
