About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-40S
The AirTAC SAIJ200X100-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 60-100 mm, letting you dial back the nominal 100 mm stroke by up to 40 mm during commissioning. This massive 200 mm bore delivers 15080 N of pull force at 0.5 MPa, making it suitable for heavy-duty pressing and lifting.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It uses PT tapered ports sized G3/4 and operates at 30-500 mm/s. The rear adjuster acts purely as a mechanical stop to set end positions and cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-40S Is Used
Heavy Press Tuning
Dial in the exact 60-100 mm pressing depth on large metal forming equipment without physically swapping out the cylinder body.
Product Changeover
Quickly adjust the end-stop position on automated assembly lines when switching between different large product sizes.
Heavy Lifting Setup
Fine-tune the lift height of massive 15080 N payloads during machine commissioning to prevent mechanical collisions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX100-40S the Right Cylinder?
Choose this adjustable model when you need precise end-position tuning without swapping cylinders or adding external stops on your heavy machinery. If you require less force, stepping down to a 160 mm bore yields 9425 N of pull force at 0.5 MPa; conversely, the 200 mm bore is optimal when maximum thrust is paramount. Because the stroke is 100 mm, side-load risks are manageable, but long unsupported strokes still need an external guide.
For an exact ISO 15552 replacement, match the 200 mm bore, 100 mm stroke, 40 mm adjustment, PT G3/4 ports, SUS304 rod, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster is a travel stop, not a lock; for true load-holding without live pressure, use an external rod lock, or explore the SAIL or BSAI cylinder series.
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 SAIJ200 Adjustable Cylinder SAIJ200BX100-40S FAQ
The rear adjuster screw acts as a mechanical stop that trims the effective travel back by up to 40 mm. This gives you a usable stroke window of 60-100 mm, allowing fine-tuning of the end position at commissioning without changing the cylinder.
At 0.5 MPa operating pressure, it provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
