The AirTAC Airtac SAIJ40 Adjustable Cylinder SAIJ40BX195-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 195mm stroke, G1/4 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 SAIJ40X195-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the effective travel by up to 100 mm. This creates a highly flexible usable stroke window of 95 to 195 mm, letting you fine-tune the retract end-position during commissioning without swapping out the barrel or adding external stops. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa.
Built with a SUS304 stainless steel rod (option B), this unit is well-suited for environments where corrosion resistance is a priority. It uses a PT tapered port thread and includes variable air cushions at both ends to decelerate the load smoothly. The rear adjuster acts strictly as a travel stop for end-position tuning, so it does not hold the load without live air pressure.

Dial in the exact retract position from 95 to 195 mm during product size transitions without disassembling the cylinder or adding external stopper blocks.
Perfect the final resting position of a tooling plate during commissioning by turning the rear adjuster screw to absorb mechanical tolerance.
Leverage the SUS304 stainless steel rod for packaging or food-grade washdown lines where standard carbon steel rods would rust.
Choose this 40 mm bore when you need 628 N of push force at 0.5 MPa, stepping up from a 32 mm bore that provides 402 N, or stepping down from a 63 mm bore that yields 1559 N. The massive 100 mm adjustment range is ideal for machines that undergo frequent product-size changeovers, replacing the need to maintain an inventory of fixed-stroke SAI cylinders for every variant.
When configuring your ISO 15552 replacement, match the 40 mm bore, 195 mm stroke, PT port thread, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. Because this is a 195 mm stroke, side loading is minimal, but for any stroke of 300 mm or more, you should add an external guide to support the rod.
Quick checklist
At 0.5 MPa operating pressure, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 128 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 195 mm stroke by up to 100 mm. This provides a usable travel window of 95 to 195 mm. The adjuster only sets the end position and does not lock or hold the load without continuous air pressure.
