The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X300-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 300mm 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.
The AirTAC SAIJ100X300-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 7068N push force at 0.9 MPa and features a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors. The integrated rear adjusting screw allows you to fine-tune the end position, providing a usable travel window of 290-300 mm for this 300 mm nominal stroke.
This 100 mm bore unit uses a G1/2 port and a durable M20x1.5 rod thread, handling speeds of 30-800 mm/s with variable air cushions at both ends. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster functions strictly as a travel stop for commissioning precision, not a load-holding lock, meaning live air pressure is required to maintain position.

Dial in the exact 290-300 mm travel window during machine commissioning to perfect pressing or clamping depth without adding external stopper blocks.
Quickly adapt the cylinder's retract end position on packaging lines when switching product formats, using the rear screw to accommodate new size requirements.
Leverage the 7068N push force at 0.9 MPa to move heavy pallets or fixtures, relying on the adjustable stop to fine-tune the final resting position.
Choose this 100 mm bore adjustable cylinder when your application requires heavy thrust (7068N push at 0.9 MPa) alongside precise end-position tuning during machine setup or product changeover. If your force requirements are lower, stepping down to an 80 mm bore yields 4523N push at 0.9 MPa, whereas moving up to 125 mm provides 11045N. The 10 mm adjustment window is ideal for dialing in exact 290-300 mm travel without swapping physical cylinders.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 300 mm stroke, G1/2 PT port, and desired mounting hardware. Because the nominal stroke is 300 mm, an external guide is recommended to prevent excessive side-load on the rod. For applications needing true load-holding without continuous air pressure, select a SAIL or BSAI lock model instead of this standard SAIJ, as the rear adjuster only sets the travel end and does not brake the load.
Quick checklist
This 100 mm bore cylinder generates 3927N push and 3681N pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 7068N, with a maximum rated force of 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 10 mm, creating a 290-300 mm usable travel window. It is a travel stop for fine-tuning end positions, not a load-holding lock, so live air is required to maintain position.
