Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-10
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 230mm 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 SAIJ80X230-10
The AirTAC SAIJ80X230-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N of push force at 0.5 MPa and features a 25mm carbon steel rod with an M20x1.5 thread. By turning the rear screw, you achieve a precise 220 to 230mm usable travel window, perfect for dialing in end positions during commissioning without swapping out hardware.
This adjustable-stroke model uses a PT tapered port (G3/8) and relies on variable air cushions at both ends to decelerate the load. The rear mechanism acts strictly as a travel stop, not a lock, meaning it cannot hold a load without live air pressure. For position holding, an external pilot-operated check valve or an AirTAC SAIL lock cylinder is required. The extruded aluminum barrel includes dual sensor grooves, ready for CMSE reed or DMSE electronic switches if a magnet is added later.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-10 Is Used
Machine Changeover
Quickly fine-tune the 220-230mm retract stop when switching product sizes on a packaging line, avoiding the need to physically swap cylinders.
End-Position Calibration
Dial in the exact end-of-stroke position during initial commissioning to prevent mechanical crashes, using the rear screw rather than external shims.
High-Force Clamping
Leverage the 2513N push force at 0.5 MPa to secure heavy workpieces, using the minor 10mm adjustment to set the precise clamping depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-10 the Right Cylinder?
Choose this 80mm bore when an application demands higher thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but does not require the full 3927N push force of a 100mm unit. The 10mm adjustment range is ideal for setups requiring minor end-position tweaks rather than massive travel changes. Because the nominal stroke is 230mm, the 25mm rod handles moderate side loads well, though any long unsupported overhang should still use an external guide.
To match this exact ISO 15552 footprint for a direct replacement, confirm the 80mm bore, 230mm stroke, 10mm adjustment range, PT G3/8 port, and standard carbon steel rod. The compatible mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets. If your machine changeover requires variable end-stops rather than a fixed SAI cylinder, this SAIJ configuration provides that flexibility.

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 SAIJ80X230-10 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm, creating a usable travel window of 220 to 230mm. This stopper decelerates the piston at the retract end but does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, the SAIJ80X230-10 provides 2513N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.9 MPa.
