About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-30
The AirTAC SAIJ100X90-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 90 mm stroke with a mechanical adjustment range of 30 mm, creating a precise 60-90 mm usable travel window for dialing in final end positions. Delivering 7068N of push force at 0.9 MPa, it integrates a robust M20x1.5 piston rod and 36 mm variable air cushions at both ends.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, though this unit ships without a magnet. The rear adjuster acts purely as a travel stop to fine-tune deceleration and end positions without adding external stops, but it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-30 Is Used
Machine Changeover
Fine-tune the 60-90 mm travel window during product size changes on a packaging line without physically replacing the cylinder.
End-Position Tuning
Dial in the exact retracted position during commissioning using the rear stopper, ensuring precise mechanical alignment.
Corrosive Forming
Leverage the 7068N push force and SUS304 stainless steel rod for pressing or forming tasks in washdown environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-30 the Right Cylinder?
Choose this 100 mm bore cylinder when an application demands high thrust—stepping up from a 63 mm bore yields 2805N push at 0.7 MPa, while stepping down to an 80 mm bore reduces it to 4523N. The adjustable stroke is ideal for machine setup and product changeover, allowing operators to trim the travel window mechanically rather than swapping out a fixed-stroke SAI cylinder. To match this ISO 15552 interchangeable cylinder exactly, specify bore 100, stroke 90, adjustment 30, PT port thread, and SUS304 (B) rod material.
Because the stroke is under 300 mm, side-load stress on the M20x1.5 rod is manageable without an external guide. Remember that the rear stopper and air cushions only set travel ends; they are not a lock. For fail-safe load holding without live air, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
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 SAIJ100BX90-30 FAQ
At 0.9 MPa, this 100 mm bore cylinder provides 7068N of push force and 3681N of pull force. It operates efficiently at speeds between 30 and 800 mm/s.
The rear adjusting screw acts as a mechanical stop, allowing you to trim the effective travel from 90 mm down to 60 mm. It sets the end position but does not lock the load without continuous air pressure.
