About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-20
The AirTAC SAIJ80X195-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5 MPa, utilizing a 25mm carbon steel rod and a G3/8 port. The integrated rear adjusting screw allows you to shorten the effective stroke by up to 20mm, providing a usable travel window of 175-195mm for precise end-position tuning.
This adjuster functions strictly as a mechanical stop to set the retract position and works alongside the standard variable air cushions at both ends. It does not hold the load without live air pressure. The extruded aluminum barrel features sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE electronic switches if a magnet is added later.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-20 Is Used
Machine Changeover
Dial in the 175-195mm stroke window during product size changes on a packaging line without physically swapping cylinders.
Variable End-Stop Setup
Fine-tune the retract position at commissioning to achieve exact end-of-travel positioning for tooling alignment.
Assembly Actuation
Provides 2513N of push force at 0.5 MPa for pressing or lifting components, with a 20mm buffer for mechanical adjustment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-20 the Right Cylinder?
Choose this 80mm bore when your application requires higher thrust than a 63mm bore (which provides 1559N push at 0.5 MPa) but does not need the full 3927N push force of a 100mm unit. The adjustable stroke is ideal for machine setups requiring variable end-stops during commissioning or product changeover, saving you from swapping out a fixed-stroke SAI cylinder or adding external stops. To replace an ISO 15552 cylinder, match the 80mm bore, 195mm stroke, 20mm adjustment, PT port thread, and mounting choice from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the stroke approaches 200mm, ensure proper external guiding to prevent excessive side-load on the 25mm rod. For applications requiring true load-holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ80X195-20 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach up to 4523N push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 195mm nominal stroke by up to 20mm, giving a usable travel window of 175-195mm. It sets the end position but does not lock the load without live air pressure.
