Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 100mm 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 ACQJ32X100-40SB
The AirTAC ACQJ32X100-40SB is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut to fine-tune the extend end position. With a 100 mm total stroke and a 40 mm adjustment window, the usable extend range spans 60 to 100 mm. The retract stroke remains completely unaffected. An M12x1.25 adjuster screw sets the limit without requiring parts replacement.
Because the piston area is unchanged, output force matches a standard ACQ exactly, delivering 402.1 N push and 301.6 N pull at 0.5 MPa. This SB configuration includes a male M14x1.5 piston rod end for direct load coupling and a built-in magnet for position sensing. The body uses fixed elastomer bumpers rather than adjustable air cushions and operates between 0.15 and 1.0 MPa.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 100 mm |
| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| 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 | 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 ACQJ32X100-40SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during setup. The external stop allows operators to shift the extend position for different raw material lengths without swapping cylinders.
Packaging Changeover
Adapt sorting pushers quickly when switching between box sizes on a packaging line. The 60 to 100 mm usable range accommodates varied carton depths on the fly.
Assembly Press Trials
Establish the perfect pressing depth for inserting bearings on an automated assembly press. Technicians can test multiple extend endpoints safely before locking the nut down.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40SB the Right Cylinder?
When sizing this 32 mm bore actuator, consider the neighbouring bores: a 25 mm unit yields 245.4 N push, while a 40 mm unit provides 628.3 N at 0.5 MPa. If your machine never requires end-position adjustments, a fixed-stroke ACQ cylinder provides the same holding power in a simpler package. To order this adjustable variant, confirm the 32 mm bore, 100 mm full stroke, 40 mm window, the S magnet option, and the B male 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 ACQJ32X100-40SB FAQ
This 32 mm bore 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 100 mm, but the external adjuster allows you to shorten the extend stroke by up to 40 mm, yielding a usable extend range of 60 to 100 mm.
No, the adjuster changes only the stroke length, not the piston area, so force remains identical to a standard ACQ. The S option includes a piston magnet compatible with both reed and electronic solid-state switches. The cylinder uses fixed elastomer bumpers for end-of-stroke deceleration instead of adjustable air cushions.
