About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-40
The AirTAC SAIJ100X90-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 90 mm stroke that can be fine-tuned down by up to 40 mm, creating a 50-90 mm usable travel window for precise end-position calibration. Delivering a robust 5497 N of push force at 0.7 MPa, it handles heavy positioning tasks with ease.
This variant uses a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-40 Is Used
Machine Setup Changeover
Dial in the exact end-position during product size changes on a line, utilizing the 50-90 mm travel window without bolting on external stops.
Variable End-Stop Tuning
Fine-tune the retract distance at commissioning to perfect the seating of heavy components using the rear mechanical stopper.
Heavy Assembly Positioning
Leverage the 5497 N push force at 0.7 MPa to move and position substantial jigs or workpieces accurately within the adjusted travel limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-40 the Right Cylinder?
Choose this 100 mm bore when 50 mm (1374 N at 0.5 MPa) is insufficient, but you want to avoid the larger 125 mm size. The 40 mm adjustment range is ideal for product changeovers, allowing you to shift the end-stop without swapping the cylinder or adding external stops. For load-holding without continuous air, select a SAIL or BSAI cylinder instead, as this adjuster is not a lock.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 100 mm bore, 90 mm stroke, 40 mm adjustment, G1/2 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet. Since the 90 mm stroke is under 300 mm, side-load concerns are minimal, though the 25 mm rod and M20x1.5 thread handle standard stresses reliably.
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 SAIJ100BX90-40 FAQ
At a 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. It can deliver up to 7068 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 90 mm nominal stroke by up to 40 mm. This creates a 50-90 mm usable travel window for fine-tuning the end position at commissioning without replacing the cylinder.
