About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-75
The AirTAC SAIJ80X95-75 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features an 80mm bore delivering 2513N of push force at 0.5 MPa, paired with a 95mm nominal stroke that can be dialed back by up to 75mm. This creates a highly flexible 20-95mm usable travel window, allowing precise end-position tuning during commissioning without swapping out the cylinder.
This variant is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification. The rear adjuster acts strictly as a travel stop to set deceleration, not as a lock to hold loads without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-75 Is Used
Product Changeover
Dial in the 20-95mm travel window rapidly during packaging line format changes to accommodate different carton sizes without changing hardware.
Commissioning Calibration
Fine-tune the retract end-position during machine setup to perfect the pressing force, avoiding the need for external mechanical stops.
Variable End Stops
Use the 75mm adjustment range to test multiple extension depths in automated assembly stations before finalizing the mechanical cycle.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-75 the Right Cylinder?
Choose this 80mm bore cylinder when an application demands high thrust (2513N push at 0.5 MPa) alongside variable end-stop positioning. If the force requirement is lower, stepping down to a 63mm bore provides 1559N of push force, whereas stepping up to a 100mm bore yields 3927N. The SAIJ80X95-75 is selected over a fixed-stroke SAI cylinder when machine setups require frequent product-size changeovers, utilizing the 75mm adjustment range to adapt the stroke on the fly.
Because the nominal stroke is 95mm, side-load risks are minimal, but the load must still be guided externally if lateral forces are present. Remember that the rear adjuster and air cushions only manage travel end deceleration; they do not function as a brake. For applications requiring true load-holding without continuous air pressure, an AirTAC SAIL (locking) or BSAI (clamp-lock) cylinder is necessary. This profile cylinder is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: 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 SAIJ80BX95-75 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 that shortens the effective stroke. With a 95mm nominal stroke and a 75mm adjustment code, the usable travel window can be fine-tuned anywhere from 20mm to 95mm.
