About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-10
The AirTAC SAIJ100X750-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for demanding automation. It features a 100mm bore generating 5497N of push force at 0.7MPa, complete with a SUS304 stainless steel rod for superior corrosion resistance. The integrated rear stopper provides a usable travel window of 740-750mm, allowing you to dial in the exact end position without external hardware.
This model uses a G1/2 port and incorporates adjustable air cushions at both ends to manage kinetic energy. The rear adjuster acts purely as a travel stop to fine-tune positioning during commissioning; it is not a lock and will not hold the load without live air. For position holding, a SAIL or BSAI cylinder is required. Mounting options include the standard SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-10 Is Used
Machine Setup & Changeover
Dial in the 740-750mm travel window during product changeovers to set new end positions instantly without machining new external stops.
Variable End Stops
Adjust the retract position on the fly to accommodate varying package sizes or processing depths on moving lines.
Heavy-Duty Positioning
Leverage the 5497N push force at 0.7MPa to shift heavy pallets or tooling, using the rear stopper to fine-tune the final resting coordinate.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-10 the Right Cylinder?
Select this 100mm bore cylinder when your application requires high thrust up to 7068N at 0.9MPa and precise end-position tuning. The 10mm adjustment window is ideal for product-size changeovers on a line, letting you shorten the 750mm stroke by up to 10mm without swapping the cylinder. If your force requirements are lower, stepping down to an 80mm bore yields 4523N at 0.9MPa, while stepping up to 125mm provides 11045N. Because the 750mm stroke is long, an external guide is recommended to prevent excessive side-loading on the rod.
When replacing an ISO 15552 cylinder, match the 100mm bore, 750mm stroke, 10mm adjustment, PT tapered port threads, and the chosen mounting accessory. Note that this unit lacks a magnet; if sensor feedback is needed, select a -S model to utilize CMSE reed or DMSE electronic switches in the dual-side sensor grooves.
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 SAIJ100BX750-10 FAQ
This 100mm bore cylinder provides a push force of 5497N at 0.7MPa and 7068N at 0.9MPa. The pull force is 3681N at 0.7MPa and 4712N at 0.9MPa.
A rear screw stopper lets you trim the effective travel back by up to 10mm from the 750mm nominal stroke, creating a 740-750mm usable window. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
