The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ140X10-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø140mm bore and 10mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.
The ACQJ140X10-10SB is a big-bore JIS compact pneumatic cylinder featuring a double-acting single rod and an external extend stop. A threaded M27x2.0 mechanical adjuster paired with a lock nut lets you dial the forward end position down to a 0-10 mm usable range. The return stroke remains fixed at its original 10 mm length.
Because the piston area stays constant, output force matches a standard ACQ exactly, yielding 7696.9 N push at 0.5 MPa. This SB variant includes a male M30x1.5 rod end for direct load coupling, an integrated piston magnet for position sensing, and fixed NBR bumpers to absorb impact energy.

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.
| Pressure | Push force | Pull force |

| 0.5 MPa | 7697 N | 7295 N |
| 0.7 MPa | 10776 N | — |
| Max (@1.0 MPa) | 1570 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.

Dial in the exact clamping depth on heavy stamping presses during initial tool setup without machining custom spacer blocks.
Adapt large machining clamps for different part families quickly by turning the external stop to shift the forward limit.
Establish the perfect bearing seating depth on automated lines by testing various extend endpoints safely before locking the nut.
Selecting this 140 mm bore actuator provides massive thrust up to 1570 kgf at 1.0 MPa. If your application requires less force, stepping down to a 125 mm bore yields 6135.9 N push at 0.5 MPa, while moving up to the 160 mm option increases that figure to 10053.1 N. A fixed-stroke ACQ suffices if your forward position never changes, but this model is essential for trial positioning. Confirm your ordering code specifies the 10 mm stroke, 10 mm window, S magnet, and B male rod thread.
Quick checklist
This 140 mm bore cylinder operates at 0.15-1.0 MPa and delivers 7696.9 N push and 7294.8 N pull at 0.5 MPa, or 10775.7 N push at 0.7 MPa, with a maximum push of 1570 kgf. The full stroke is 10 mm, but the external stop provides a usable extend range of 0-10 mm. The retract stroke is unaffected.
The external M27x2.0 threaded stop limits only the extend length, so force remains identical to a standard ACQ. It features fixed NBR bumpers rather than adjustable air cushions. Note that a plain compact cylinder drifts on air loss; for fail-safe load holding, install an external rod lock.
