About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-75S
The AirTAC SAIJ100X90-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 3927N push force at 0.5 MPa and a 3681N pull force. The integrated rear stopper allows you to fine-tune the effective travel down from the 90mm nominal stroke, creating a 15-90mm adjustable window for precise end-position tuning without external stops.
This model includes a SUS304 stainless steel rod for corrosion resistance and a magnet for position sensing. It supports AirTAC CMSE reed and DMSE electronic solid-state switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. The PT tapered port and M20x1.5 rod thread handle high flow and side loads, while variable air cushions at both ends manage deceleration across the 30-800mm/s speed range.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-75S Is Used
Machine Setup Tuning
Dial in the exact 15-90mm travel window during commissioning to perfect end-positioning without swapping cylinders.
Product Size Changeover
Quickly adapt the stroke stop on automated lines when processing different product dimensions.
Variable End Stops
Use the rear adjuster to create custom stroke limits for delicate positioning tasks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-75S the Right Cylinder?
Choose this 100mm bore when 80mm (2513N push) is insufficient but 125mm is too large. An adjustable-stroke cylinder is selected over a fixed SAI when a machine requires variable end-stops or product-size changeovers. The rear screw acts as a travel stop, not a lock; it will not hold the load without live air. For fail-safe load holding, use an SAIL or BSAI cylinder.
To match this ISO 15552 cylinder, specify a 100mm bore, 90mm stroke, 75mm adjustment range, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and a magnet (-S). Because the stroke is under 300mm, side-load stress is moderate, but the 25mm rod still requires an external guide for heavy lateral 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 SAIJ100BX90-75S FAQ
At 0.5 MPa it provides 3927N push and 3681N pull. At 0.7 MPa the push force is 5497N, and it reaches 7068N at 0.9 MPa.
The rear adjuster screw trims the 90mm nominal stroke by up to 75mm, giving a usable 15-90mm travel window. It functions as a mechanical stop, not a lock.
