About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-30S
The AirTAC SAIJ80X195-30-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 0.5 MPa and features a 25mm carbon steel rod with an M20x1.5 thread. Because this specific SKU includes a magnet (-S), it is fully compatible with AirTAC CMSE reed and DMSE electronic sensors seated in the dual-side barrel grooves.
The integrated stopper screw provides a 30mm adjustment range, letting you dial in the effective travel anywhere within a 165-195mm window without swapping hardware. This extruded aluminum cylinder uses PT tapered port threads (G3/8) and relies on adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-30S Is Used
Product Changeovers
Quickly reconfigure the 165-195mm retract distance on packaging lines when switching to different carton sizes, eliminating the need to physically swap out cylinders.
End-Position Calibration
Fine-tune the final resting position of tooling during machine commissioning, using the 30mm rear stopper to dial in exact contact without mechanical shims.
Variable End Stops
Adapt clamping or pressing force travel on the fly for multi-model assembly lines, relying on the 2513N push force to secure varying workpiece sizes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-30S the Right Cylinder?
Choose this 80mm bore when an application requires higher thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa), but without the larger footprint of a 100mm unit. The adjustable 165-195mm travel window is ideal for machine setups requiring frequent product changeovers, allowing operators to fine-tune the retract end-position on the fly instead of adding external stops. If your setup needs to hold a load securely without continuous live air pressure, note that this cylinder's rear adjuster acts only as a travel stop, not a lock; you should instead explore an AirTAC SAIL or BSAI series.
For an exact ISO 15552 replacement match, verify the 80mm bore, 195mm nominal stroke, 30mm adjustment code, PT G3/8 port, and the -S magnet option. Since the 195mm stroke approaches a length where side-loading can amplify wear, ensure the piston rod is properly supported by an external guide to maximize seal and bearing life.
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 SAIJ80X195-30S FAQ
It features a rear mechanical stopper that allows you to shorten the effective stroke by up to 30mm. This creates a usable travel window of 165-195mm, letting you set the exact retract end-position during commissioning without changing the cylinder.
At a 0.5 MPa operating pressure, this double-acting cylinder provides 2513N of push force and 2268N of pull force. It can reach up to 4523N push force at its maximum 0.9 MPa pressure rating.
