About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-30S
The AirTAC SAIJ80X100-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 100 mm travel by up to 30 mm. This creates a precise 70-100 mm usable stroke window, perfect for fine-tuning end positions during commissioning without swapping hardware. It delivers robust thrust, generating 2513 N of push force and 2268 N of pull force at 0.5 MPa.
Fitted with a PT tapered port and a carbon steel rod, this -S variant includes a magnet for position sensing. You can mount CMSE reed or DMSE electronic switches directly into the extruded aluminum barrel's dual sensor grooves. The adjuster acts purely as a mechanical stop to set the retract end position, working alongside the standard adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-30S Is Used
Machine Changeover
Dial in the 70-100 mm stroke window instantly on the factory floor when switching between product sizes, avoiding mechanical rebuilds.
End-Position Tuning
Fine-tune the retract end-stop during initial commissioning to perfect the seating of heavy 80 mm bore tooling without external shims.
Variable End Stops
Adjust the travel limit on the fly for automated processes that require flexible retraction distances within a 100 mm nominal span.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-30S the Right Cylinder?
Choose this 80 mm bore when an application requires substantial force—such as the 2513 N push at 0.5 MPa—exceeding the 982 N push capacity of a 50 mm neighbor, but without stepping up to the heavier 100 mm bore. The adjustable 70-100 mm travel window is ideal for machine setups requiring variable end-stops or product-size changeovers, eliminating the need to bolt on external stops or buy multiple fixed-stroke SAI cylinders.
Because the rear screw functions only as a travel stop and not a locking device, this cylinder will not hold a load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI model. This SKU features PT ports, a carbon steel rod, and the -S magnet option. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ80X100-30S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. If you increase the pressure to 0.7 MPa, the push force rises to 3518 N.
The rear adjuster screw allows you to mechanically shorten the 100 mm nominal stroke by up to 30 mm, providing a usable travel window of 70 to 100 mm. The screw acts as a physical stop to set the end position, but it is not a lock and requires live air to hold the load.
