About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-100S
The AirTAC SAIJ100X800-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers robust thrust, generating 7068N of push force at 0.9 MPa, making it suitable for heavy-duty positioning tasks. The integrated -S magnet enables position sensing across both sensor grooves using CMSE reed or DMSE electronic solid-state switches.
This model features an 800 mm nominal stroke paired with a 100 mm adjustment range, yielding a usable travel window of 700-800 mm. This built-in adjustability allows you to fine-tune the retract end-position during commissioning or product changeovers without swapping the cylinder or adding external stops. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while omitting tie-rods.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract position within the 700-800 mm window during machine commissioning to accommodate different product sizes without mechanical rework.
Heavy-Duty Forming Press
Leverage the 7068N push force at 0.9 MPa to actuate heavy forming or stamping assemblies, using the rear stop to precisely set the bottom dead center.
Long-Stroke Diversion Gate
Control large diverters on material handling lines, relying on the 800 mm travel to span wide conveyors while adjusting the stopper to match lane widths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-100S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 4523N push at 0.9 MPa) is insufficient for your load requirements. The adjustable stroke is ideal for applications requiring variable end-stops or precise setup tuning, whereas a fixed-stroke SAI cylinder is better for repeatable, single-position tasks. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock, a SAIL air-released lock, or a BSAI clamp-lock cylinder.
Because this cylinder features an 800 mm stroke, the 25 mm carbon steel rod and M20x1.5 rod thread will experience leverage forces under side-loading. An external guide mechanism is strongly recommended to prevent premature seal wear and rod bending over this long travel distance. This configuration includes a PT tapered port thread, operates at speeds of 30-800 mm/s, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting options.

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 SAIJ100X800-100S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder generates a push force of 7068N and a pull force of 3681N. The maximum thrust at 1.0 MPa is 801 kgf.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 100 mm, providing a usable travel window of 700-800 mm. It only sets the end position and does not lock the load without continuous air pressure.
