The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 175mm 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 SAIJ100X175-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 155 and 175 mm. Delivering a robust 3927 N of push force at 0.5 MPa, it is built to handle demanding actuation tasks while maintaining standard ISO 15552 mounting dimensions.
This model features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered ports. It includes adjustable air cushions at both ends to manage kinetic energy, but note that these cushions and the rear stopper only decelerate the load; they do not hold it without live air pressure. For position holding, consider a SAIL or BSAI series cylinder.

Dial in the exact retraction end-stop within the 155-175 mm window when switching product sizes on a packaging line, eliminating the need to swap out the entire actuator.
Fine-tune the stroke at commissioning to compensate for mechanical tolerances, ensuring the 3927 N push force hits the exact target point without adding external stopper blocks.
Leverage the SUS304 stainless steel rod in environments requiring higher moisture or chemical resistance while maintaining standard ISO 15552 footprint compatibility.
Choose this 100 mm bore when you need higher thrust than a neighboring 80 mm cylinder, which provides 2513 N of push force at 0.5 MPa. The SAIJ100X175-20 is selected over a fixed-stroke SAI when a machine setup requires a variable end-stop to dial in the exact retraction point during commissioning or product changeover. When matching an ISO 15552 replacement, verify the 100 mm bore, 175 mm stroke, 20 mm adjustment, PT G1/2 port, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Quick checklist
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. It can reach a maximum push force of 7068 N at 0.9 MPa.
The rear adjusting screw allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 155 to 175 mm. This stopper sets the end position but does not lock the load without live air pressure.
