Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-100
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 650mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-100
The AirTAC SAIJ100X650-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 550-650 mm usable travel window, allowing you to trim up to 100 mm off the 650 mm nominal stroke during commissioning without adding external stops. It delivers a robust push force of 7068 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This model incorporates a 25 mm carbon steel rod with an M20x1.5 thread, providing substantial rigidity and side-load resistance. It uses a G1/2 port and includes variable air cushions at both ends to decelerate the load. The extruded aluminum barrel features dual sensor grooves, and because no magnet is specified, you would add the -S option if you later need CMSE reed or DMSE electronic solid-state switches.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-100 Is Used
Variable End Stops
Dial in the exact 550 to 650 mm retract position when feeding different width materials on a conveyor line without changing the cylinder.
Machine Changeover
Quickly reconfigure the stroke length during product size changeovers to minimize setup downtime on automated packaging equipment.
Heavy-Duty Positioning
Leverage the 7068 N push force at 0.9 MPa to move heavy jigs into exact alignment, using the 100 mm adjustment window for final calibration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-100 the Right Cylinder?
Choose this 100 mm bore when the 80 mm variant (providing 4523 N push at 0.9 MPa) is insufficient for your load. The adjustable stroke is ideal for product changeovers, letting you fine-tune the retract end-position on the fly rather than swapping to a fixed-stroke SAI cylinder. When matching your ISO 15552 replacement, verify the 650 mm stroke, 100 mm adjustment range, G1/2 PT threaded port, and your mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Because the stroke is 650 mm, the extended rod is highly susceptible to bending under offset loads; always use an external guide to prevent side-load damage. Additionally, the rear adjuster acts only as a travel stop, not a brake—this cylinder will not hold its load without live air. For fail-safe load holding, 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 SAIJ100X650-100 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 100 mm, providing a usable travel window between 550 mm and 650 mm. It acts as a mechanical stop to fine-tune the end position.
At 0.9 MPa, the 100 mm bore provides a push force of 7068 N and a pull force of 3681 N. It operates at speeds between 30 and 800 mm/s.
