About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX750-10
The AirTAC SAIJ80X750-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. With a nominal 750 mm stroke and a 10 mm adjustment screw, it provides a usable travel window of 740-750 mm, letting you dial in the exact end-stop at commissioning without adding external stops. The 80 mm bore delivers 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa.
This variant uses a SUS304 stainless steel rod for corrosion resistance and a PT tapered port thread. It carries the standard SAIJ mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX750-10 Is Used
Product Changeover
Dial in the 740-750 mm end-stop during line changeovers to accommodate different product lengths without replacing the cylinder.
Material Handling
Provides 2513 N of push force at 0.5 MPa to index heavy pallets, with the rear screw allowing precise positioning at commissioning.
Machine Setup
Fine-tune the retract position during initial machine build, eliminating the need to bolt on external physical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX750-10 the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires 2513 N of push force at 0.5 MPa, bridging the gap between the 63 mm bore (1559 N) and the 100 mm bore (3927 N). The adjustable stroke is ideal for machine setup and product changeover, allowing variable end-stops without swapping the cylinder. For strokes of 750 mm, the 25 mm rod diameter handles high side loads, but an external guide is recommended to prevent rod bending.
Because the rear adjuster only sets the travel end and the air cushions manage deceleration, this cylinder will not hold a load without live air. For load-holding without pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. This model is dimensionally interchangeable per ISO 15552 mounting interfaces.
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 SAIJ80BX750-10 FAQ
The rear adjuster screw allows you to shorten the effective travel from the 750 mm nominal stroke down to 740 mm, giving a 740-750 mm usable window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force increases to 4523 N.
