About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-20S
The AirTAC SAIJ100X95-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 95 mm stroke with a 20 mm adjustment range, yielding a usable travel window of 75-95 mm. Delivering 3927 N of push force at 0.5 MPa, it is built for heavy-duty positioning. A -S magnet is included for standard position sensing.
This model features a carbon steel rod and PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position at commissioning; it is not a lock and will not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-20S Is Used
Machine Setup & Changeover
Dial in the exact end-position during commissioning or product size changes without swapping cylinders or adding external mechanical stops.
Variable End-Stop Positioning
Utilize the 75-95 mm travel window to fine-tune the retract distance for delicate operations requiring precise physical boundaries.
Heavy-Duty Assembly Lines
Leverage the 3927 N push force at 0.5 MPa to move substantial jigs or fixtures while maintaining the flexibility to adjust the stroke.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-20S the Right Cylinder?
Choose this 100 mm bore when the 50 mm bore's 982 N push force at 0.5 MPa is insufficient, but you want to avoid stepping up to the 125 mm class. The adjustable 75-95 mm travel window is perfect for applications requiring variable end-stops or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. The 25 mm rod and M20x1.5 thread handle high side-loads, though any stroke over 300 mm would require an external guide. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100X95-20S FAQ
The SAIJ100X95-20-S has a rear adjusting screw that allows you to shorten the effective stroke by up to 20 mm. This creates a usable travel window of 75-95 mm, letting you fine-tune the end position without changing the cylinder.
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can deliver up to 7068 N of push force at 0.9 MPa.
