About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X145-100S
The AirTAC SAIJ80X145-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 2513N push force at 0.5 MPa. Because this specific SKU carries a -100 adjustment code on a 145mm nominal stroke, you gain an exceptionally wide usable travel window of 45 to 145mm. This allows you to dial in the exact retract end-position during commissioning without swapping out the physical cylinder.
Fitted with a PT tapered port and a 25mm carbon steel rod, this bore size handles heavy loads effectively. The integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded barrel grooves. The rear adjuster acts purely as a mechanical stop for deceleration and positioning, meaning live air pressure is required to hold the load in place.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X145-100S Is Used
Variable Product Changeover
Quickly reconfigure the retract distance from 45mm up to 145mm on packaging lines running varied container sizes, eliminating the need to physically swap cylinders during format changes.
Commissioning End-Stop Tuning
Fine-tune the exact end-of-stroke position during machine setup to perfect the mechanical timing, preventing hard crashes by using the 100mm adjustment range to absorb positioning tolerances.
Heavy Clamping Positioning
Leverage the 2513N push force to secure heavy workpieces while using the rear screw to precisely set the clamp's retracted clearance gap for robotic loading.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X145-100S the Right Cylinder?
Select this 80mm bore when an application demands high thrust—such as 2513N push or 2268N pull at 0.5 MPa—along with extreme flexibility in the retract distance. If you need less force, stepping down to a 63mm bore yields 1559N push force, whereas moving up to a 100mm bore provides 3927N. Choose this adjustable-stroke SAIJ variant over a fixed SAI when a machine handles multiple product sizes and requires rapid end-stop changes without adding external stops.
To replace this cylinder per ISO 15552 mounting interface dimensions, match the 80mm bore, 145mm stroke, -100 adjustment, PT G3/8 port, and -S magnet. The compatible mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without continuous air pressure, note that neither the rear adjuster nor the air cushions function as a lock; you must integrate an external pilot-operated check valve or select an AirTAC SAIL or BSAI 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 SAIJ80X145-100S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can achieve up to 4523N push force at 0.9 MPa.
The rear adjuster screw lets you mechanically shorten the effective stroke from its 145mm nominal length down to 45mm. This creates a 45-145mm travel window for precise end-position tuning at commissioning, though it functions as a stop and not a load-holding lock.
