About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-10
The AirTAC SAIJ100X220-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 7068N push force at 0.9 MPa and uses a SUS304 stainless steel rod for superior corrosion resistance. The integrated rear stopper allows you to fine-tune the usable travel window down from a 220 mm nominal stroke to a precise 210-220 mm range, which is ideal for dialing in final end positions during commissioning without swapping out hardware.
This model features PT tapered ports and lacks a piston magnet, meaning it is not equipped for position sensing out of the box. The extruded aluminum barrel design incorporates sensor grooves on both sides should you later require a magnet-equipped variant. It supports a speed range of 30-800 mm/s and relies on variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-10 Is Used
Machine Setup Calibration
Dial in the exact 210-220 mm travel window during initial commissioning to compensate for mechanical tolerances without machining new stopper blocks.
Product Size Changeover
Quickly adjust the retract end-position by up to 10 mm on automated lines when switching between product variants, minimizing downtime.
Heavy Forming End-Stop
Leverage the 7068N push force and SUS304 rod for robust positioning in metal forming or bending cells, fine-tuning the stroke to match material thickness.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-10 the Right Cylinder?
Selecting this 100 mm bore cylinder makes sense when your application demands high thrust but requires minor end-position tweaks on the fly. If you need less force, stepping down to an 80 mm bore yields 4523N at 0.9 MPa, but the SAIJ100X220-10 guarantees robust performance for heavier fixtures. The 10 mm adjustment range is specifically useful for compensating for mechanical tolerance stack-ups during machine assembly or product changeover. Because the stroke is 220 mm, you should ensure adequate external guiding to prevent excessive side-load on the SUS304 rod.
When matching ISO 15552 replacements, verify the 100 mm bore, 220 mm stroke, 10 mm adjustment, PT port thread, and basic mounting footprint. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series instead. The mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100BX220-10 FAQ
At a 0.9 MPa operating pressure, this 100 mm bore cylinder generates a push force of 7068N and a pull force of 5497N. It can deliver a maximum of 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the 220 mm nominal length down to 210 mm. This allows precise end-position tuning at commissioning, but it does not lock or hold the load without continuous air pressure.
