About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-75S
The AirTAC SAIJ80X95-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push force at 0.5 MPa. Its SUS304 stainless steel rod provides superior corrosion resistance, while the integrated magnet supports CMSE reed and DMSE electronic sensors for precise position detection. With a PT tapered port and G3/8 threading, it ensures reliable pneumatic flow.
This model features a nominal 95mm stroke that can be dialed back by up to 75mm, creating a highly versatile 20-95mm usable travel window. This wide adjustment range allows for exact end-position tuning during commissioning or product changeovers without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-75S Is Used
Variable End-Stop Positioning
Ideal for assembly lines requiring multiple stroke lengths, allowing operators to dial in the exact 20-95mm travel window without changing hardware.
Product Changeover
Quickly adapt to different package sizes on a conveyor by turning the rear adjuster, reducing downtime during format transitions.
Machining Clamping
Provides robust 2513N clamping force at 0.5 MPa with fine-tuned retraction to avoid over-travel and workpiece damage.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-75S the Right Cylinder?
Choose this 80mm bore cylinder when an application requires substantial force (2513N push at 0.5 MPa) alongside highly variable end-stops; if less force is needed, a 63mm bore offers 1559N. The 75mm adjustment range on a 95mm stroke is ideal for machines handling multiple product sizes, acting as a physical stop rather than a lock. For load-holding without live air pressure, consider a SAIL or BSAI cylinder instead. To match this ISO 15552 interchangeable unit, specify the 80mm bore, 95mm stroke, PT port, and -S magnet.
Because the nominal stroke is 95mm, the 25mm rod handles side loads adequately, though external guides are recommended for any unsupported loads. The rear adjuster and variable air cushions decelerate the piston, but neither will hold the load dynamically. This cylinder omits FB, CA, CB, and CR mounts, focusing on the most common profile mounting styles.
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 SAIJ80BX95-75S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 95mm nominal stroke by up to 75mm. This creates a usable travel window of 20-95mm, enabling fine-tuning of the end position without adding external stops.
