Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100S
The AirTAC SAIJ100X700-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N of push force at 0.5 MPa and features a 25mm carbon steel piston rod with an M20x1.5 thread. The integrated magnet enables position sensing with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves.
This model provides a usable travel window of 600 to 700mm, allowing you to dial back the nominal stroke by up to 100mm. The rear adjusting screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device; for load-holding without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 600-700mm window during machine setup, eliminating the need to fabricate shims or external stopper blocks.
Product Changeover
Quickly adapt the stroke length on a packaging line when switching to different product sizes, using the 100mm rear adjustment screw to modify the travel end.
Sensor-Ready Actuation
Leverage the built-in magnet with DMSE electronic sensors to confirm end-of-stroke positions while using the mechanical adjuster to sync physical movement.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-100S the Right Cylinder?
Select this 100mm bore cylinder when an 80mm bore (delivering 2513N push at 0.5 MPa) cannot provide enough force, but you want to avoid stepping up to a 125mm bore which yields 6136N. The adjustable 600-700mm travel window is ideal for product changeovers, letting you fine-tune the end-stop on the machine without swapping the cylinder.
Because the stroke is 700mm, the long unsupported rod is susceptible to side-loading; an external guide is recommended to prevent premature seal wear. This SAIJ unit uses PT tapered ports and a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552.
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 SAIJ100X700-100S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjuster screw lets you mechanically shorten the effective stroke from 700mm down to 600mm. This creates a 600-700mm travel window for fine-tuning the end position at commissioning, but it acts only as a stop and does not lock the load without air pressure.
