About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-30S
The AirTAC SAIJ100X35-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, featuring a standard carbon steel rod and a PT tapered port. It provides a 3927N push force at 0.5 MPa, placing it in a heavy-duty thrust class for substantial loads. The integrated -S magnet allows direct mounting of CMSE reed and DMSE electronic sensors into the dual-side extruded barrel grooves for precise position feedback.
With a 35mm nominal stroke and a 30mm adjustment code, this model yields a highly versatile 5-35mm usable travel window. This built-in rear stopper allows you to dial in the exact end-position at commissioning without swapping hardware. The adjuster acts purely as a travel stop and relies on the variable air cushions to decelerate the load; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-30S Is Used
Product Changeover
Dial the stroke from 35mm down to 5mm instantly on the production line when switching to a shorter package or component, avoiding mechanical cylinder swaps.
End-Position Tuning
Fine-tune the final retract position during machine commissioning to achieve exact contact pressure without adding external physical stops.
Heavy-Duty Clamping
Leverage the 100mm bore's 7068N push force at 0.9 MPa to securely clamp large workpieces while adjusting the clamp depth as needed.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-30S the Right Cylinder?
Select this 100mm bore when an application requires significant force, such as 5497N push at 0.7 MPa, but demands variable end-stops for frequent product changeovers. If you need less force, stepping down to an 80mm bore yields 2513N push at 0.5 MPa. Choose the adjustable SAIJ over a fixed SAI when you need on-the-fly fine-tuning of the retract end position. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air, consider the SAIL or BSAI series. To match this exact unit for an ISO 15552 replacement, specify the 100mm bore, 35mm stroke, 30mm adjustment, PT port, standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), and the -S magnet option.

- ✓ 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 SAIJ100X35-30S FAQ
At 0.5 MPa, the 100mm bore provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster allows you to trim the 35mm nominal stroke back by up to 30mm, creating a 5-35mm usable travel window. The adjuster acts as a mechanical stop and does not lock the load without continuous air pressure.
