Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-100B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-100B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X100-100B
The ACQJ40X100-100B is a double-acting JIS compact cylinder featuring a 40mm bore and a 100mm full stroke. An external threaded stop with a lock nut limits the extend travel, letting you fine-tune the end position directly on the machine. The usable extend range spans 0 to 100mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, force output is identical to a standard ACQ of this bore. At 0.5 MPa it delivers 628.3N push and 527.8N pull. This unit includes a male M14x1.5 rod-end thread for direct coupling and a fixed elastomer bumper at each end. The body retains sensor grooves, though this specific model ships without a magnet.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-100B |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X100-100B Is Used
Machining Fixture Stops
Dial in the exact extend position for varying part sizes on a CNC lathe without machining new stop collars.
Carton Changeover Diverters
Quickly alter the extend reach on a packaging conveyor to handle different box formats during product changeover.
Press Trial Positions
Test different end-of-stroke contact points on an assembly press prototype before finalizing the mechanical hard stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-100B the Right Cylinder?
For 0.5 MPa pneumatic push requirements, this 40mm bore yields 628.3N. Stepping down to a 32mm bore drops push to 402.1N, while a 50mm bore raises it to 981.8N. If your application never requires stroke adjustments, a fixed-stroke ACQ cylinder will provide the same force in a simpler package. When ordering this adjustable variant, confirm the 40mm bore, 100mm full stroke, 100mm adjustment window, the male rod thread (-B), and whether you need the magnet option (-S) for solid-state or reed switch 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 ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X100-100B FAQ
It delivers 628.3N push and 527.8N pull at 0.5 MPa, 879.6N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The full stroke is 100mm, and with the 100mm adjustment window, the usable extend range is 0 to 100mm.
The external M12x1.25 threaded stop with lock nut limits only the extend travel, leaving the retract stroke and force unchanged. Deceleration is handled by a fixed elastomer bumper, not an adjustable air cushion. Note that a plain ACQ-type cylinder will not hold its load on air loss; use an external rod lock for fail-safe holding.
