About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-40
The AirTAC SAIJ32X140-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 100-140 mm, allowing you to dial back the 140 mm nominal stroke by up to 40 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set end positions and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-40 Is Used
Machine Setup Tuning
Fine-tune the 100-140 mm travel window during initial commissioning to perfectly align tooling without machining external stopper blocks.
Product Size Changeover
Quickly adapt end positions on packaging lines handling varying carton sizes by dialing the rear adjuster up to 40 mm.
Light-Duty Positioning
Move light components with 402 N of push force while relying on the built-in stop to set precise retract distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-40 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of push force at 0.5 MPa and an adaptable end-stop. If your application requires less force, step down to a 25 mm bore; if you need significantly more thrust, step up to a 40 mm bore which provides 628 N. The adjustable stroke is ideal for product changeovers where exact end positions vary, eliminating the need to physically swap cylinders. For load-holding without continuous air pressure, select the SAIL or BSAI series instead. This SAIJ model uses PT port threads and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32BX140-40 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke from 140 mm down to 100 mm. This creates a 40 mm adjustable window for fine-tuning end positions without adding external stops.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers 82 kgf.
