About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-30
The AirTAC SAIJ32X800-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 770-800 mm usable travel window by allowing you to dial back the 800 mm nominal stroke by up to 30 mm. Operating at 0.15-1.0 MPa, it delivers 402 N of push thrust and 345 N of pull thrust at 0.5 MPa, fitting compact pneumatic setups requiring precise end-position tuning.
This model features a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threading on its G1/8 air supply. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 770-800 mm window during machine commissioning without swapping the cylinder or adding external stops.
Product Changeover
Quickly adapt the retract stroke by up to 30 mm on a packaging line when handling different product sizes, ensuring precise positioning.
Tolerance Compensation
Absorb mechanical variations in long-stroke assemblies by fine-tuning the end-stop position to meet strict dimensional requirements.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-30 the Right Cylinder?
Choose this 32 mm bore when your application requires lighter forces (402 N push at 0.5 MPa) rather than stepping up to the 50 mm bore, which yields 982 N. The adjustable stroke is selected over a fixed SAI cylinder when you need to compensate for mechanical tolerances during commissioning or alter the retract end-stop without adding external shims. To replace this ISO 15552 cylinder, match the 32 mm bore, 800 mm stroke, 30 mm adjustment, PT G1/8 port, SUS304 rod, and no-magnet configuration. Because the stroke is 800 mm, the 12 mm rod requires an external guide to prevent excessive side-load deflection. For load-holding without live air, use an external rod lock or pilot-operated check valve, as the adjuster is not a brake. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX800-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 800 mm nominal stroke by up to 30 mm, providing a usable travel window of 770-800 mm. It only sets the end position and does not lock the load without live air.
