About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-20
The AirTAC SAIJ100X35-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 15-35 mm usable travel window. Delivering 3927 N of push force at 0.5 MPa, it handles heavy-duty positioning with precision.
This variant uses a SUS304 stainless steel rod for corrosion resistance and features PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, though this non-magnet version does not support position sensing.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-20 Is Used
Machine Setup Tuning
Fine-tune the 15-35 mm travel window during initial commissioning to achieve exact contact forces without machining external stops.
Product Changeover
Quickly adjust the retract end-position on a packaging line when switching to a different product size.
Heavy-Duty Clamping
Leverage the 3927 N push force at 0.5 MPa for robust clamping of large components, dialing back the stroke as needed.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX35-20 the Right Cylinder?
Select this 100 mm bore cylinder when your application demands high thrust—3927 N push at 0.5 MPa or 5497 N at 0.7 MPa. If you need less force, a 80 mm bore provides 2513 N push at 0.5 MPa. The 20 mm adjustment range is ideal for dialing in exact end positions during commissioning without swapping cylinders.
Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold a load without live air. For load-holding requirements, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX35-20 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw allows you to shorten the 35 mm nominal stroke by up to 20 mm, providing a usable travel window of 15 to 35 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
