About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX80-10S
The AirTAC SAIJ80X80-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning without external stops. It provides a usable travel window of 70 to 80 mm, letting you dial back the nominal 80 mm stroke by up to 10 mm during commissioning or product changeovers. Delivering a robust 2513 N push force at 0.5 MPa, it handles demanding cyclic loads while maintaining standard ISO 15552 mounting dimensions.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance in wet or washdown environments. It includes a magnet for position sensing, compatible with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The PT tapered port threads ensure a tight, reliable pneumatic connection, while the 25 mm rod diameter and M20x1.5 thread offer high rigidity and excellent side-load capacity.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX80-10S Is Used
Machine Setup Tuning
Dial in the exact 70-80 mm end-of-stroke position during initial commissioning without machining custom spacers or swapping cylinders.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slight variations in incoming product sizes on a high-mix assembly line.
Heavy-Duty Clamping
Leverage the 2513 N push force at 0.5 MPa for secure, high-force clamping of heavy components, fine-tuning the clamp depth on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX80-10S the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires substantial thrust, such as 2513 N at 0.5 MPa, combined with on-the-fly travel adjustment. If your process needs less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa; conversely, moving up to a 100 mm bore provides 3927 N. The adjustable stroke is ideal for setups requiring variable end-stops, replacing fixed-stroke SAI cylinders when exact end-positioning is unknown until commissioning. Remember, the rear adjuster is a travel stop, not a lock; the cylinder will not hold a load without live air. For load-holding, consider the SAIL or BSAI series. When matching an ISO 15552 replacement, verify the 80 mm bore, 80 mm stroke, 10 mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.

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 SAIJ80BX80-10S FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective travel from 80 mm down to 70 mm, creating a 70-80 mm usable window. The adjuster sets the end position but does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ80X80-10-S generates a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
