About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-20
The AirTAC SAIJ80X230-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 2513N of push force at 0.5 MPa. It features a 25mm carbon steel piston rod and a PT-tapered G3/8 port. The integrated -20 adjustment mechanism allows you to fine-tune the effective travel down from the 230mm nominal stroke, providing a usable window of 210-230mm without requiring external stops.
This adjuster acts purely as a mechanical stop for end-position tuning and works alongside the standard variable air cushions at both ends. It does not lock or hold the load without continuous live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is specified later.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-20 Is Used
Machine Changeover
Dial in the 210-230mm travel window during product size transitions to set precise end positions without swapping out the entire cylinder.
Variable End-Stop Setup
Use the rear mechanical stopper to fine-tune the retract distance at commissioning, eliminating the need to bolt on custom external spacers.
Assembly Line Calibration
Leverage the 2513N push force and adjustable stroke to perfectly position heavy components on an assembly line during initial setup.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-20 the Right Cylinder?
Select this 80mm bore cylinder when an application requires trimming the retract distance during commissioning or product changeover, rather than relying on a fixed-stroke SAI variant. If your setup demands less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa; conversely, a 100mm bore provides 3927N for heavier loads. Because the 230mm stroke exceeds 300mm is false here, side-load concerns are moderate, but the 25mm rod still handles standard guide loads well.
To match this exact ISO 15552 replacement, ensure you specify the 80mm bore, 230mm stroke, 20mm adjustment range, G3/8 PT port, and carbon steel rod. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, deliberately omitting FB, CA, CB, and CR options. For applications requiring true load-holding without air pressure, consider the SAIL or BSAI series instead of relying on this adjuster.
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 SAIJ80X230-20 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 20mm, creating a usable travel window of 210-230mm. It is designed for end-position tuning and does not function as a lock to hold the load without live air pressure.
