About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-50S
The AirTAC SAIJ100X95-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 7068N of push force at 0.9 MPa. It features a carbon steel piston rod and a PT tapered G1/2 port. With the integrated -S magnet, it supports CMSE reed and DMSE solid-state sensors housed neatly within the dual-side extruded aluminum barrel grooves.
This model provides a usable travel window of 45-95 mm, allowing you to dial back the nominal 95 mm stroke by up to 50 mm. This built-in rear stopper enables precise end-position tuning during commissioning or product changeovers without adding external stops. The adjuster acts solely as a travel stop to set deceleration alongside the variable air cushions, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-50S Is Used
Product Changeover
Dial the stroke back from 95 mm to 45 mm instantly to accommodate different product lengths on the same conveyor line without swapping hardware.
Commissioning Tuning
Fine-tune the exact end-of-travel position during machine setup using the rear screw, ensuring perfect alignment without external shims.
Assembly Pressing
Leverage the 7068N push force at 0.9 MPa for light pressing tasks, adjusting the press depth precisely to match varying component heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-50S the Right Cylinder?
Choose this adjustable-stroke unit over a fixed SAI cylinder when your application demands frequent end-stop adjustments or variable product sizes on a single line. If you need to step down the bore size, the 80 mm variant offers 4523N of push force at 0.9 MPa, while moving up to the 125 mm bore yields 11045N. For load-holding without continuous air pressure, this cylinder is not a lock; you should instead look at the SAIL or BSAI series, or employ an external rod lock.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 95 mm stroke, 50 mm adjustment range, PT G1/2 port, and your required mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this unit utilizes a 25 mm rod and M20x1.5 thread to handle higher side loads, any stroke of 300 mm or more on this bore size would still require an external guide to prevent rod deflection.
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 SAIJ100X95-50S FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder generates 7068N of push force and 3681N of pull force. It reaches a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 95 mm down to 45 mm. This creates a 45-95 mm usable window for fine-tuning the retract end position during setup.
