About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-10
The AirTAC SAIJ100X65-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 55-65 mm usable travel window by allowing you to trim up to 10 mm off the 65 mm nominal stroke, delivering 5497 N of push force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This unit uses a SUS304 stainless steel rod for corrosion resistance and a PT tapered port thread. The rear adjuster acts purely as a travel stop to fine-tune end positions during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-10 Is Used
Machine Setup Tuning
Dial in the exact retract position during initial commissioning without adding external stopper blocks to the fixture.
Product Changeover
Quickly adjust the 55-65 mm travel window to accommodate slight size variations when switching product lines.
Assembly Pressing
Delivers 5497 N of thrust at 0.7 MPa for pressing bearings, with fine-tuning to prevent over-travel and part damage.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-10 the Right Cylinder?
Select this 100 mm bore cylinder when a 50 mm bore (1374 N push at 0.5 MPa) lacks thrust, but a 125 mm bore is physically too large. The 10 mm adjustable stroke is ideal for dialing in exact end-stops during machine setup or product changeover without swapping components. Unlike a fixed SAI cylinder, this rear screw mechanism allows precise end-position tuning on the fly.
To match this ISO 15552 replacement exactly, specify: 100 mm bore, 65 mm stroke, 10 mm adjustment, PT port thread, and SUS304 (B) rod material. Because it lacks a magnet (-S), it cannot use electronic DMSE or reed CMSE sensors without modification. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR 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 SAIJ100BX65-10 FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. It can reach a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 65 mm down to as little as 55 mm. It only sets the travel end and does not hold the load without continuous air pressure.
