About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-75S
The AirTAC SAIJ80X195-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N of push force at 0.5MPa and features a generous 75mm adjustment range, creating a usable travel window between 120mm and 195mm. This wide tuning band allows operators to dial in the exact retract end-position during commissioning or product changeovers without swapping out the physical actuator.
Built with a standard carbon steel rod and PT tapered ports, this unit includes a magnet (-S) for position sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. It utilizes a variable air cushion at both ends to decelerate the load smoothly, while the rear stopper sets the final travel limit.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-75S Is Used
Product Changeovers
Quickly reconfigure the retract distance on packaging lines when switching to different carton sizes, utilizing the 120-195mm window to avoid mechanical rebuilds.
End-Position Tuning
Fine-tune the exact stopping point of a tooling head during machine commissioning to perfect alignment without machining custom spacers.
Variable Diverter Stops
Act as an adjustable flow diverter on a conveyor, moving the stop position back by up to 75mm to accommodate varying pallet depths on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-75S the Right Cylinder?
Choose this 80mm bore when an application requires higher thrust than a 63mm cylinder (which provides 1559N push at 0.5MPa) but does not need the full 3927N output of a 100mm bore. The adjustable stroke is ideal for machines processing varying product sizes, as the end-stop can be fine-tuned on the fly instead of adding external physical stops. When specifying a replacement, match the 80mm bore, 195mm nominal stroke, 75mm adjuster, PT port threads, and the -S magnet requirement.
Because the nominal stroke is 195mm, the 25mm rod and M20x1.5 rod thread provide substantial rigidity, but any long unsupported stroke still requires an external guide to prevent excessive side-loading. Remember that the rear adjuster acts only as a travel stop and the air cushion provides deceleration; neither will hold the load without live air pressure. For true load-holding without continuous air, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. Mounting options include 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 SAIJ80X195-75S FAQ
The rear adjuster acts as a mechanical stop that shortens the retract stroke. For this model, the 195mm nominal stroke can be dialed back by up to 75mm, providing a usable travel window of 120-195mm. The standard variable air cushion handles deceleration, but the adjuster itself does not lock the load without live air pressure.
At 0.5MPa, it provides 2513N of push force and 2268N of pull force. This -S model includes a magnet for use with AirTAC CMSE reed switches and DMSE electronic solid-state sensors, which mount directly into the dual sensor grooves on the extruded aluminum barrel.
