About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-50
The AirTAC SAIJ100X95-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 45 to 95 mm, allowing you to dial back the nominal 95 mm stroke by up to 50 mm during commissioning without adding external stops. It delivers a robust 3927 N of push force at 0.5 MPa.
This model uses a G1/2 port and a 25 mm carbon steel rod with an M20x1.5 thread, providing high rigidity against side loads. It supports a speed range of 30-800 mm/s and includes adjustable air cushions at both ends. The extruded aluminum barrel features sensor grooves on both sides, though this specific SKU is configured without a magnet for position sensing.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-50 Is Used
Machine Setup & Changeover
Fine-tune the retract end-position during product changeovers, utilizing the 45-95 mm travel window to adapt machinery to new component sizes instantly.
Variable End Stops
Set precise retraction limits on assembly presses without swapping out the entire cylinder or fabricating custom external mechanical stops.
Press Fit Tuning
Dial in the exact insertion depth for press-fit operations, ensuring consistent assembly force and depth across varying batch tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-50 the Right Cylinder?
Choose this 100 mm bore when 50 mm (982 N at 0.5 MPa) lacks the necessary thrust, but you want to avoid the larger footprint of a 125 mm cylinder. The 50 mm adjustment range is ideal for product size changeovers on a line, letting you set variable end positions on the fly. For any stroke at or near 95 mm, ensure proper alignment, but note that longer unsupported strokes generally require an external guide to prevent rod bending.
This cylinder is dimensionally interchangeable per ISO 15552 standards. It uses a PT tapered port thread and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding without pressure, 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 SAIJ100X95-50 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw allows you to shorten the 95 mm nominal stroke by up to 50 mm, creating a 45 to 95 mm usable travel window. This stopper decelerates the travel end but does not lock the load without live air pressure.
