Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 300mm 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 ACQJ32X300-10SB
The ACQJ32X300-10SB is a double-acting JIS compact cylinder with a 300mm full stroke and a 10mm external extend-stop window, allowing you to dial in the forward end-position precisely from 290mm to 300mm directly on the machine. Because the threaded stop only limits travel length, the piston area remains the same, meaning the output force is identical to a standard ACQ of this bore. This made-to-order long-stroke variant exceeds the standard 100mm maximum for a 32mm bore, offering extended reach for deep-access machinery.
Equipped with a male M14x1.5 piston rod end (-B) for direct load coupling and a built-in magnet (-S) for position sensing, it integrates seamlessly with reed or solid-state electronic switches. The unit operates at 30-500 mm/s within a 0.15-1.0 MPa pressure range, relying on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion.

| 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 |

| 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 ACQJ32X300-10SB Is Used
Deep-Reach Press Fixtures
Dial in the exact 290-300mm forward clamping depth on extended-reach press tools without swapping out cylinders when material thicknesses change.
Extended Transfer Stops
Fine-tune the end stop on long-stroke conveyor diverters to accommodate varying product lengths during production line changeovers.
Automated Assembly Trial
Test and set precise 300mm end positions on new automated assembly machinery before locking down the external M12x1.25 adjuster nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10SB the Right Cylinder?
Select this 32mm bore option when your setup requires exact forward positioning within a 290-300mm travel window alongside a male rod thread. If your application only needs a fixed forward reach, a standard ACQ32X300 cylinder will suffice without the external adjuster. When sizing for power, this bore yields 402.1N push and 301.6N pull at 0.5MPa; dropping to a 25mm bore reduces push to 245.4N, while stepping up to a 40mm bore increases push to 628.3N. To order, confirm the 32mm bore, 300mm full stroke, 10mm adjuster window, PT1/8 port, and the S/B options.
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 ACQJ32X300-10SB FAQ
The usable extend range is 290-300mm (300mm full stroke minus the 10mm window). Force is unchanged from a standard ACQ: 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The retract stroke remains unaffected.
The external threaded stop only limits the extend travel distance, so it does not alter the piston area or reduce the output force. End-of-stroke deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. For high-speed or high-energy loads, an external shock absorber is recommended.
