About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-30
The AirTAC SAIJ100X95-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927 N push force at 0.5 MPa. By integrating a 30 mm adjustment mechanism, this unit creates a usable travel window of 65 to 95 mm. This allows operators to dial in the exact retract position during commissioning without swapping out the entire actuator or fabricating external stops.
Beyond its fine-tuning capability, the 25 mm carbon steel rod and M20x1.5 thread provide substantial rigidity for handling heavy loads. The extruded aluminum barrel features sensor grooves on both sides, ready to accept CMSE or DMSE switches if a magnet is specified later. It utilizes a G1/2 port and includes variable air cushions at both ends to manage kinetic energy, though the adjuster acts strictly as a travel stop rather than a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 65-95 mm window during machine commissioning to achieve precise positioning without adding external shims.
Product Changeover
Quickly adapt the stroke length on automated lines when handling different product sizes, minimizing downtime between production runs.
Heavy Assembly Pressing
Leverage the 3927 N push force at 0.5 MPa to seat heavy components, using the adjustable stop to accommodate various part heights safely.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-30 the Right Cylinder?
Choose this 100 mm bore when a smaller 80 mm unit (providing 2513 N push at 0.5 MPa) lacks the necessary thrust, but before stepping up to a 125 mm bore that might be physically oversized for the envelope. The adjustable stroke is specifically beneficial for machine setups requiring variable end-stops or frequent product changeovers, offering flexibility that a fixed-stroke SAI cannot match.
When ordering a direct ISO 15552 replacement, verify the 95 mm stroke, 30 mm adjustment range, PT tapered port thread, and mounting style. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-load risks are moderate, but always ensure adequate external guiding for heavy loads. Note that this cylinder does not hold its position without live air; for positive locking, consider the SAIL or BSAI series.
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 SAIJ100X95-30 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N push at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 95 mm nominal stroke by up to 30 mm. This creates a usable travel window of 65 to 95 mm, though it does not lock the load without continuous air pressure.
