About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-30S
The AirTAC SAIJ100X35-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 5 to 35 mm. Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore unit is built with a SUS304 stainless steel rod for superior corrosion resistance and features a magnet for CMSE reed and DMSE electronic sensors.
The integrated rear adjusting screw acts as a hard stop to fine-tune the end position at commissioning without adding external physical stops. It is crucial to note that this adjuster only sets the travel end and does not hold the load without live air pressure; for true load-holding, consider an external rod lock or pilot-operated check valve.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-30S Is Used
Machine Setup Calibration
Dial in the exact clamping end-position during equipment commissioning, trimming the 35 mm stroke down to a precise 5 mm micro-stroke without swapping hardware.
Product Size Changeover
Quickly adjust the retract stop to accommodate varying product heights on a conveyor line, using the rear screw rather than adding mechanical spacers.
Corrosive Environment Actuation
Leverage the 3927 N push force and SUS304 stainless steel rod for high-thrust positioning tasks in washdown or corrosive manufacturing settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-30S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust—such as 3927 N at 0.5 MPa or 5497 N at 0.7 MPa—and the exact extend distance must be dialed in on-site. If your setup needs less force, the 80 mm bore provides 2513 N at 0.5 MPa. The SAIJ100X35-30-S features PT tapered port threads and a stainless steel rod, making it ideal for environments where corrosion is a concern. To match this ISO 15552 replacement exactly, specify the 100 mm bore, 35 mm stroke, 30 mm adjustment, PT ports, and the -S magnet option.
Because this is a profile cylinder rather than a tie-rod design, it utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. For any stroke of 300 mm or more, ensure you add an external guide to handle side loads.
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 SAIJ100BX35-30S FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa push increases to 5497 N. It operates on filtered air between 0.15 and 1.0 MPa, runs at speeds of 30-800 mm/s, and uses a G1/2 port.
The rear adjuster screw lets you mechanically shorten the effective travel from 35 mm down to as little as 5 mm, creating a 5-35 mm usable window. This allows precise end-position tuning during commissioning, but the adjuster acts only as a stop and does not lock the load without air pressure.
