About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-75S
The AirTAC SAIJ100X80-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa and provides a usable travel window of 5-80mm, allowing you to trim the nominal 80mm stroke by up to 75mm during commissioning without swapping hardware.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE reed or DMSE electronic sensors. It uses PT tapered ports and retains the standard extruded aluminum barrel with sensor grooves on both sides. The rear stopper sets the end position, but it does not lock the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-75S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 5 to 80mm on packaging machines that process varying container heights without changing cylinders.
Product Changeover
Quickly reconfigure the stroke window on automated lines during format changes, saving setup time and eliminating external stop hardware.
High-Force Clamping
Leverage the 3927N push force at 0.5 MPa to securely clamp heavy workpieces while fine-tuning the clamping depth at the rear screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-75S the Right Cylinder?
Choose this 100mm bore when a smaller 80mm bore (offering 2513N push at 0.5 MPa) lacks the necessary thrust, but a 125mm bore is excessive. The wide 75mm adjustment window is ideal for machines requiring highly variable end-stops or frequent product changeovers, replacing the need for fixed-stroke SAI cylinders and external stops.
For ISO 15552 replacements, match the 100mm bore, 80mm stroke, 75mm adjustment, PT ports, and the -S magnet. Because the stroke is under 300mm, side-load risks are moderate, but the 25mm rod and M20x1.5 thread handle standard loads well. If you need to hold a load without continuous air, use a SAIL lock or BSAI clamp-lock cylinder instead of relying on this adjuster.
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 SAIJ100BX80-75S FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 80mm down to 5mm. This provides a 5-80mm usable window for fine-tuning end positions at commissioning.
At 0.5 MPa, it provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
