Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-30S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 95mm 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 SAIJ100X95-30S
The AirTAC SAIJ100X95-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 95 mm travel to a precise 65-95 mm window. It delivers substantial thrust, pushing 3927 N at 0.5 MPa and up to 7068 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks. A standard carbon steel rod and M20x1.5 rod thread provide robust resistance to side loading, while the extruded aluminum barrel design maintains compatibility with standard ISO 15552 mounting dimensions.
This model includes a magnet (-S) for position sensing, supporting AirTAC CMSE reed switches and DMSE solid-state electronic sensors via the dual-side sensor grooves. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning or product changeovers without adding external stops. It is not a locking device, so load-holding without live air requires a separate SAIL or BSAI cylinder.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-30S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 65 to 95 mm during machine commissioning to accommodate varying material thicknesses without swapping out the entire cylinder.
Product Size Changeover
Quickly adjust the stroke end-position on a packaging line when switching between different product sizes, utilizing the 30 mm adjustment range for rapid setup.
Heavy-Duty Clamping
Leverage the 7068 N push force at 0.9 MPa to secure heavy workpieces, using the rear stopper to fine-tune the clamping depth precisely.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-30S the Right Cylinder?
Choose this 100 mm bore adjustable-stroke cylinder when your application requires high force and variable end-position tuning within a 65-95 mm travel window. If your thrust requirements are lower, stepping down to an 80 mm bore reduces the push force to 2513 N at 0.5 MPa, optimizing air consumption. Conversely, if you need even greater power, a 125 mm bore increases the 0.5 MPa push force to 6136 N. Because this is a profile cylinder, it uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets entirely.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 95 mm nominal stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet requirement. With a nominal stroke of 95 mm, the 25 mm rod diameter and M20x1.5 thread handle standard loads well, but always verify that your mechanical setup prevents excessive side loading on the piston rod.
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 SAIJ100X95-30S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm, creating a usable travel window of 65 to 95 mm. It functions as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
At an operating pressure of 0.5 MPa, the cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum recommended pressure of 0.9 MPa, the push force increases to 7068 N.
