About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-10S
The AirTAC SAIJ80X350-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This setup is ideal for fine-tuning end positions during commissioning without adding external stops.
Built for demanding environments, this variant uses a SUS304 stainless steel rod for superior corrosion resistance. It includes a magnet for position sensing via CMSE reed or DMSE electronic switches. With a 350mm stroke, the M20x1.5 rod thread and 25mm rod diameter handle high side loads, though an external guide is recommended for unsupported lengths.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-10S Is Used
Machine Setup & Changeover
Dial in the exact 340-350mm end position during line changeovers without swapping out the entire cylinder or adding external stopper blocks.
Variable End-Stop Positioning
Fine-tune the retract stroke by up to 10mm at commissioning to accommodate minor variations in product dimensions or tooling height.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and 2513N pull force for robust actuation in washdown or corrosive manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-10S the Right Cylinder?
Choose this 80mm bore cylinder when you need higher thrust than the 63mm bore (1559N at 0.5 MPa) but want to avoid the bulk of a 100mm bore (3927N at 0.5 MPa). The 10mm rear adjuster screw is selected over a fixed-stroke SAI when your machine setup requires variable end-stops or precise product-size changeovers.
For a 350mm stroke, always use an external guide to prevent side-load damage to the barrel. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552, featuring PT tapered ports and a mounting set including 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 SAIJ80BX350-10S FAQ
The maximum thrust is 513 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel by up to 10mm, providing a usable stroke window of 340-350mm. It acts as a mechanical stop to fine-tune the end position and does not function as a lock to hold the load without air pressure.
