About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-10S
The AirTAC SAIJ100X80-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. With a nominal stroke of 80mm and a 10mm adjustment range, it provides a usable travel window of 70-80mm. This allows you to fine-tune the retract end position precisely during commissioning without swapping out the physical cylinder.
This 100mm bore model features a carbon steel piston rod and PT tapered ports. It includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed switches and DMSE electronic sensors mounted in the dual-side sensor grooves. The rear adjuster acts strictly as a travel stop for deceleration, not a lock, meaning live air pressure is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-10S Is Used
Machine Setup & Changeover
Dial in the exact 70-80mm retract position during commissioning or product size changes without physically swapping cylinders or adding external stopper blocks.
Variable End-Stop Positioning
Ideal for assemblies requiring precise end-of-stroke tuning to accommodate part tolerances, utilizing the 10mm rear adjustment screw to set the exact travel limit.
Heavy-Duty Forming Stops
Leverage the 3927N push force at 0.5 MPa to reliably press or halt heavy workpieces, tuning the stroke end to match different material thicknesses on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-10S the Right Cylinder?
Choose this adjustable-stroke cylinder when your machine setup requires variable end-stops or frequent product-size changeovers, avoiding the need to maintain multiple fixed-stroke SAI cylinders. If your application requires less force, stepping down to an 80mm bore yields 2513N of push force at 0.5 MPa. To match this ISO 15552 cylinder for a replacement, verify the 100mm bore, 80mm nominal stroke, 10mm adjuster, PT port thread, and the -S magnet option.
For load-holding applications without continuous air pressure, note that the SAIJ rear adjuster and air cushions do not function as a brake. In such cases, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. Since this is a short 80mm stroke, side-load concerns are minimal, but always ensure proper mounting alignment.
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 SAIJ100 Adjustable Cylinder SAIJ100X80-10S FAQ
At an operating pressure of 0.5 MPa, this 100mm bore cylinder generates 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The SAIJ100X80-10-S has a nominal 80mm stroke with a 10mm adjustment range, creating a usable travel window of 70-80mm. A rear screw allows you to mechanically shorten the effective stroke to fine-tune the end position without changing the cylinder.
