About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-30S
The AirTAC SAIJ100X80-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927 N of push force at 0.5 MPa and features a 50-80 mm usable travel window, allowing you to trim the 80 mm nominal stroke back by up to 30 mm during commissioning. This built-in adjustability eliminates the need to swap out the entire cylinder or bolt on external stopper blocks when fine-tuning machine end positions.
This variant includes a piston magnet for position sensing and uses a standard carbon steel rod with PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, enabling direct mounting of CMSE reed or DMSE electronic solid-state switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-30S Is Used
End-Position Tuning
Dial in the exact retract distance within the 50-80 mm window during machine commissioning without changing the physical cylinder mounting.
Product Changeover
Quickly adjust the stroke by up to 30 mm to accommodate different product sizes on a packaging or handling line.
Variable End Stops
Replace hard external stopper blocks with the integrated rear screw for cleaner setups and precise kinetic energy management.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-30S the Right Cylinder?
Selecting this 100 mm bore cylinder provides 3927 N push and 3681 N pull force at 0.5 MPa. If your application requires less force, stepping down to an 80 mm bore yields 2513 N of push force. The adjustable 30 mm stroke window is ideal for product changeovers or variable end-stops, whereas a fixed-stroke SAI cylinder is better suited for applications with rigid, unchanging travel requirements. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100 Adjustable Cylinder SAIJ100X80-30S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the 80 mm nominal stroke by up to 30 mm, creating a 50-80 mm usable travel window. The adjuster acts as a mechanical stop to set the end position and does not function as a lock to hold the load without air pressure.
