About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-10S
The AirTAC SAIJ100X800-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial back the nominal 800 mm travel by up to 10 mm for a 790-800 mm usable window. It delivers 5497 N of push force at 0.7 MPa and features a SUS304 stainless steel rod for superior corrosion resistance.
This variant includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel carries sensor grooves on both sides, and the G1/2 port feeds the dual-end air cushions. The adjuster acts purely as a mechanical stop to fine-tune the retract end without adding external stops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-10S Is Used
Precision End-Stop Tuning
Dial in the exact 790-800 mm retract position during machine commissioning to perfect product seating without machining external stoppers.
Product Size Changeover
Quickly adapt a long-stroke assembly line to slightly shorter travel requirements by adjusting the rear screw up to 10 mm during format changes.
Corrosive Environment Handling
Leverage the SUS304 stainless steel rod and 7068 N output at 0.9 MPa to move heavy loads in washdown or mildly corrosive industrial settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-10S the Right Cylinder?
Choose this adjustable-stroke model when you need precise end-position tuning during commissioning or product changeover without swapping the cylinder. If you need less force, the 80 mm bore offers 3518 N at 0.7 MPa; if your load demands more, the 125 mm bore provides 8590 N. Because the 800 mm stroke is long, an external guide rail is recommended to handle side loads and prevent rod binding.
The rear adjuster and air cushions only set the travel end and deceleration; they do not hold the load without live air. For true load-holding without pressure, select a SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. This SAIJ is dimensionally interchangeable per ISO 15552, with a PT tapered port, SUS304 rod, and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ100BX800-10S FAQ
At 0.7 MPa it provides 5497 N of push force and 3681 N of pull force. At 0.9 MPa the push force reaches 7068 N. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 790-800 mm travel window. It acts as a mechanical stop for fine-tuning at commissioning and is not a lock, meaning it will not hold the load without live air pressure.
