About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-50
The AirTAC SAIJ80X95-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 95 mm nominal stroke to a 45 mm minimum. This creates a highly versatile 45-95 mm usable window for dialing in end positions during commissioning without swapping hardware. The 80 mm bore delivers substantial thrust, pushing 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the internal magnet. The rear screw acts purely as a mechanical stop to set the retract position, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-50 Is Used
Product Changeover
Quickly dial the retract position back by up to 50 mm when switching between packaging formats on the same line.
End-Stop Calibration
Fine-tune the final retract position during machine setup without machining external stopper blocks.
Heavy Forming Operations
Leverage the 2513 N push force at 0.5 MPa for pressing or holding tasks requiring variable travel limits.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-50 the Right Cylinder?
Choose this 80 mm bore when you need heavy force in the 4523 N range at 0.9 MPa, stepping up from a 63 mm bore that provides 2805 N. The 50 mm adjustment range is exceptionally wide for a 95 mm stroke, making it ideal for machines running multiple product sizes that require rapid changeover of the retract end-stop. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with ISO 15552 cylinders of the same bore. To match this exact configuration, specify an 80 mm bore, 95 mm stroke, 50 mm adjustment, PT ports, SUS304 rod, and no magnet. Mounting options are limited to the SAIJ subset: 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 SAIJ80 Adjustable Cylinder SAIJ80BX95-50 FAQ
A rear external screw stopper lets you mechanically shorten the stroke from the nominal 95 mm down to 45 mm, providing a 45-95 mm travel window. This allows precise end-position tuning at commissioning without replacing the cylinder.
The cylinder generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. At the maximum operating pressure of 0.9 MPa, it provides 4523 N of push force.
