About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-30S
The AirTAC SAIJ80X95-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. This yields a usable stroke window of 65-95 mm, enabling precise end-position tuning at commissioning without adding external stops. It delivers a robust 2513 N push force at 0.5 MPa and 3518 N at 0.7 MPa, making it well-suited for heavier actuation tasks.
This unit includes a SUS304 stainless steel rod for superior corrosion resistance and comes with a magnetic piston (-S) for position sensing. It is designed to work seamlessly with AirTAC CMSE reed and DMSE solid-state sensors fitted into the dual-side sensor grooves of the extruded aluminum barrel. The PT tapered port and M20x1.5 rod thread provide durable mechanical and pneumatic connections.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-30S Is Used
Machine Setup & Changeover
Dial in the exact 65-95 mm end-of-stroke position during machine commissioning or product size changes without physically swapping the cylinder.
Variable End Stops
Ideal for production lines running multiple product lengths, allowing operators to quickly adjust the retract stop within the 30 mm window.
Heavy-Duty Positioning
Leverage the 2513 N push force at 0.5 MPa to move and position heavier jigs or materials reliably in automated assembly lines.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-30S the Right Cylinder?
Choose this 80 mm bore if your application requires significantly more thrust than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa), but does not warrant the larger footprint and air consumption of a 100 mm bore. The adjustable stroke is ideal for product changeovers or variable end-stops, functioning as a travel stop rather than a load-holding lock. Because this is a plain SAIJ, it will not hold its load without live air pressure; for true locking force, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 80 mm bore, 95 mm stroke, PT port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ80BX95-30S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 95 mm nominal stroke by up to 30 mm, providing an effective usable travel window of 65 to 95 mm. It only sets the end position and does not lock the load without continuous air pressure.
