Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-30
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 95mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-30
The AirTAC SAIJ80X95-30 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 SUS304 stainless steel rod and a PT G3/8 tapered port. By turning the rear screw, you can trim the nominal 95mm stroke back by up to 30mm, creating a precise 65-95mm usable travel window for exact end-position tuning during commissioning.
This adjustable stopper allows you to dial in the retract position without swapping out the entire cylinder or adding external stops. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting, though this specific SKU omits the magnet. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for dead-air load holding, consider the SAIL or BSAI variants.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-30 Is Used
Product Changeovers
Quickly dial the retract stroke back by up to 30mm when switching product sizes on a packaging line, avoiding mechanical rebuilds.
End-Stop Calibration
Fine-tune the 65-95mm travel window during machine commissioning to achieve exact positioning without adding external stops.
High-Force Clamping
Leverage the 2513N push force at 0.5 MPa to secure heavy workpieces, using the adjustable stop to vary clamp depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX95-30 the Right Cylinder?
Select this 80mm bore when an application requires higher thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but still needs precise retract-end tuning. The 30mm adjustment window is ideal for product-size changeovers on a line, letting you shift the end stop dynamically rather than machining new hard stops. If dead-air load holding is required, note that the SAIJ adjuster is not a lock—you would need to step up to a SAIL (air-released lock) or BSAI (clamp-lock) cylinder.
To match this exact ISO 15552 replacement, verify the 95mm stroke, the 30mm adjustment requirement, the PT G3/8 port, and the SUS304 (code B) rod material. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300mm, external side-load guides are less critical, though the 25mm rod thread handles standard operational stresses well.
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 SAIJ80BX95-30 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 95mm nominal stroke by up to 30mm, providing a usable travel window of 65-95mm. It functions as a travel stop and does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, the SAIJ80X95-30 provides 2513N of push force and 2268N of pull force. It can reach up to 4523N push force at 0.9 MPa.
