About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-30S
The AirTAC SAIJ100X90-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear-mounted stroke adjuster, allowing you to fine-tune the effective travel within a 60 to 90 mm window. Delivering a robust 7068 N of push force at 0.9 MPa, it handles heavy actuation tasks while maintaining standard ISO 15552 mounting interface dimensions for direct interchangeability. The built-in -S magnet enables seamless position detection with AirTAC CMSE reed and DMSE solid-state sensors.
Because the external stop acts solely as a travel end-limit and relies on live air, this cylinder does not function as a load-holding lock; for dead-pilot pressure holding you would specify a SAIL or BSAI variant. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting, and the SAIJ series utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-30S Is Used
Product Changeover Dial-In
Quickly reconfigure end-stops for varying package sizes on a packaging line by adjusting the rear screw within the 60-90 mm window without replacing the actuator.
Press Fit Commissioning
Fine-tune the exact bottoming position during machine setup to achieve precise press fits, using the rear stopper to dial out mechanical overshoot.
Variable Diverter Stroke
Adjust the travel of a heavy-duty sorting gate on the fly to accommodate different product widths while maintaining the high force needed for positive actuation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-30S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust—stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, while this 100 mm unit provides 7068 N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, letting you dial in the exact 60-90 mm travel without swapping cylinders or adding external stops. When matching your ISO 15552 replacement, verify the 90 mm stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet requirement.
With a 90 mm stroke, the 25 mm piston rod and M20x1.5 rod thread provide excellent rigidity against side loads, though any long unsupported travel still necessitates an external guide. The standard carbon steel rod material suits general industrial environments, while the dual-sided variable air cushions ensure smooth deceleration at both ends of the stroke.
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 SAIJ100X90-30S FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 5497 N of pull force. It can deliver a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 90 mm nominal stroke by up to 30 mm, providing an effective usable travel window of 60 to 90 mm. It sets the end position but does not lock the load without continuous air pressure.
