About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-30S
The AirTAC SAIJ80X30-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. Its 30 mm nominal travel can be dialed back by up to 30 mm, yielding a usable stroke window of 0-30 mm for exact end-position calibration. Operating at 0.7 MPa, it delivers 3518 N of push force and 2268 N of pull force.
This unit includes a magnet for position sensing with CMSE reed and DMSE solid-state switches. It uses a standard carbon steel rod and PT tapered ports. The extruded aluminum barrel design incorporates sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-30S Is Used
Variable End-Stop Forming
Dial in the exact 0-30 mm travel window during machine setup to accommodate varying material thicknesses without swapping out the physical actuator.
Product Changeover Calibration
Quickly fine-tune the retract end-position on packaging lines when switching to a new package format, ensuring precise mechanical stops.
Short-Stroke Clamping
Use the high 3518 N push force and short adjustable travel to secure heavy workpieces securely during machining operations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-30S the Right Cylinder?
Select this 80 mm bore actuator when an application requires high thrust combined with variable end-stops for frequent product changeovers. If your force requirements are lower, stepping down to a 63 mm bore yields 2182 N of push force at 0.5 MPa, whereas stepping up to a 100 mm bore provides 5497 N. The rear screw on this SAIJ acts purely as a travel stop to decelerate the piston, not a lock; it will not hold a load without live air pressure. For drop-in ISO 15552 interchangeability, match the 80 mm bore, 30 mm stroke, PT ports, and the -S magnet requirement.

- ✓ 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 SAIJ80X30-30S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm. Since the nominal stroke is 30 mm, you can tune the usable travel window anywhere from 0 to 30 mm to achieve the exact end-position needed at commissioning.
At an operating pressure of 0.7 MPa, the SAIJ80X30-30-S generates 3518 N of push force and 2268 N of pull force. It can achieve a maximum thrust of 513 kgf at 1.0 MPa.
