About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-30
The AirTAC SAIJ80X100-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 2513 N push force at 0.5 MPa, utilizing a 25 mm SUS304 stainless steel rod and a PT G3/8 port. The integrated adjustment screw allows you to trim the 100 mm nominal stroke back by up to 30 mm, creating a precise 70-100 mm usable travel window for exact end-position tuning.
This adjustable stopper lets you fine-tune the retract position during commissioning or product changeovers without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-30 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 70-100 mm window during machine setup to accommodate different material thicknesses without changing hardware.
Product Size Changeover
Quickly adjust the stroke stop on packaging lines when switching between different container sizes, reducing downtime and eliminating external stop blocks.
High-Force Clamping
Leverage the 2513 N push force at 0.5 MPa to securely clamp workpieces while using the rear screw to fine-tune the clamping depth precisely.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-30 the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but does not need the full 3927 N output of a 100 mm bore. The 30 mm adjustment window is ideal for machines that process varying product sizes, allowing operators to dial in the exact retract distance on the fly instead of machining custom spacers. For a fixed end-position requirement, a standard SAI cylinder would suffice, but the SAIJ variant provides crucial flexibility.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 100 mm stroke, PT G3/8 port, and the specific 30 mm adjustment code. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 100 mm, side-load stress is minimal, though the substantial 25 mm SUS304 rod naturally handles greater off-center loads than smaller bores. If the machine requires true load-holding without continuous air pressure, select an external rod lock or a SAIL pneumatic lock cylinder instead.

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 SAIJ80BX100-30 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 100 mm nominal stroke by up to 30 mm, providing an effective 70-100 mm travel window. It only sets the end position and does not lock the load without live air.
