About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-30S
The AirTAC SAIJ100X95-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 65 to 95 mm. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
The integrated rear adjusting screw acts as a mechanical stop, allowing you to fine-tune the retract end-position during commissioning without adding external stops. It uses a G1/2 port and supports a speed range of 30-800 mm/s. For load-holding without live air pressure, this cylinder should be paired with an external rod lock or a related series like SAIL or BSAI.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-30S Is Used
Precision End-Stop Tuning
Dial in the exact retract position within the 65-95 mm window during machine commissioning without swapping cylinders or fabricating external spacers.
Product Changeover Adjustment
Quickly adapt the retract stroke by up to 30 mm on packaging lines when handling different product sizes, ensuring precise positioning.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or fixtures, using the SUS304 rod in environments where standard carbon steel rods would corrode.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-30S the Right Cylinder?
Choose this adjustable-stroke SAIJ model when your application requires precise end-position tuning at commissioning or during product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your process demands less force, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa. If you need to hold a load unpowered, remember the rear adjuster is strictly a travel stop, not a lock.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 95 mm stroke, 30 mm adjustment range, G1/2 PT port, and the -S magnet requirement. Because this unit features a 25 mm rod and M20x1.5 rod thread, it handles substantial side loads well, though any stroke over 300 mm on larger models would still require an external guide. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
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 SAIJ100BX95-30S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N push force at 0.9 MPa.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 95 mm nominal stroke by up to 30 mm, giving an effective adjustable travel window of 65 to 95 mm. It is a travel stop, not a lock, so it will not hold the load without live air pressure.
