About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-20
The AirTAC SAIJ100X130-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 130 mm stroke that can be dialed back by up to 20 mm, yielding a precise 110-130 mm usable travel window for commissioning without external stops. In the 100 mm bore class, it generates 3927 N of push force and 3681 N of pull force at 0.5 MPa.
This model features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and carries a robust 25 mm rod with an M20x1.5 thread. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. Mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-20 Is Used
Machine Setup & Changeover
Fine-tune the 110-130 mm travel window during product line changeovers to accommodate varying material thicknesses without swapping cylinders.
Variable End-Stop Tuning
Dial in the exact retract position during commissioning using the rear screw, eliminating the need to bolt on external mechanical stops.
Heavy-Duty Forming
Leverage the 3927 N push force at 0.5 MPa for pressing or forming operations where the final stroke length must be micro-adjusted on-site.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-20 the Right Cylinder?
Choose this 100 mm bore adjustable cylinder when an application demands high force (3927 N push at 0.5 MPa) alongside variable end-position tuning. If your process requires less thrust, stepping down to an 80 mm bore yields 2513 N push force. The rear adjuster acts strictly as a mechanical stop to trim the 130 mm stroke; it does not lock or hold the load without live air. For position holding without pneumatic pressure, consider the SAIL or BSAI series instead. Because the 130 mm stroke is relatively short, side-load risks are minimal, but external guides are recommended for heavy lateral loads.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 130 mm stroke, 20 mm adjustment range, PT tapered port threads, and the desired mounting interface. This SKU does not include a magnet (-S), so position sensing requires a separate magnet-equipped variant if needed.
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 SAIJ100AX130-20 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the 130 mm nominal stroke by up to 20 mm, creating a 110-130 mm usable travel window. It only sets the end position and does not hold the load without live air pressure.
