About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-30S
The AirTAC SAIJ80X60-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 30-60 mm from the 60 mm nominal stroke. This on-machine tuning eliminates the need to swap cylinders or bolt on external stops during product changeovers. It delivers a robust 2513 N of push force at 0.5 MPa and uses a SUS304 stainless steel rod for superior corrosion resistance.
Equipped with a magnet for position sensing, this unit works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors mounted in the dual-side extruded barrel grooves. The PT tapered port threads ensure a tight pneumatic seal, while the integrated adjustable air cushions at both ends manage end-of-stroke deceleration. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-30S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 30-60 mm window to accommodate varying material thicknesses on the fly without changing out the entire actuator.
Machine Format Changeover
Quickly reconfigure the stroke end-position during product line transitions using the rear adjusting screw, drastically reducing commissioning and setup downtime.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and 2513 N push force to securely press components in washdown or mildly corrosive industrial environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-30S the Right Cylinder?
Choose this 80 mm bore when your application requires the 2513 N push force at 0.5 MPa, which sits neatly between the 1559 N output of a 63 mm cylinder and the 3927 N capacity of a 100 mm bore. The 30 mm adjustment range is ideal for machinery requiring variable end-stops during format changes, providing setup flexibility that a fixed-stroke SAI cylinder cannot match. If your process demands true load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is a stop, not a lock.
To match this ISO 15552 interchangeable replacement exactly, specify an 80 mm bore, 60 mm stroke, 30 mm adjustment range, PT port threads, and the -S magnet option. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The 25 mm rod and M20x1.5 thread provide excellent rigidity, though even with this robust rod, any long unsupported stroke exceeding 300 mm would require an external guide to prevent side-loading damage.

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 SAIJ80BX60-30S FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. It can reach up to 4523 N push force at the maximum 0.9 MPa pressure.
The rear adjuster screw allows you to shorten the effective travel by up to 30 mm, creating a usable 30-60 mm stroke window. This ISO 15552 profile cylinder uses the screw as an end-position stop for fine-tuning, but it is not a lock and cannot hold the load without live air pressure.
