The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 170mm stroke, G1/8 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 SAIJ32X170-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 170 mm stroke that can be fine-tuned down by up to 40 mm, yielding a usable travel window of 130-170 mm to perfectly dial in retract end positions. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnetic piston (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid supply is routed through PT tapered G1/8 ports. The rear adjuster functions strictly as a travel stop for deceleration and positioning, not as a load-holding lock.

Dial in the exact retract distance within the 130-170 mm window during machine commissioning to accommodate varying workpiece lengths without external stops.
Quickly adjust the stroke by up to 40 mm on packaging lines when switching between different product sizes, minimizing downtime.
Leverage the SUS304 stainless steel rod for precise component positioning tasks in environments where standard carbon steel rods would degrade.
Select this 32 mm bore adjustable cylinder when an application requires exact end-position tuning during commissioning or product changeover without swapping out physical components. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa; conversely, dropping to a smaller bore sacrifices too much power for most standard fixtures. Because this model features a 170 mm stroke, it remains well within the 1000 mm maximum standard stroke limit for this bore size.
The -40 mm adjustment window is ideal for accommodating minor dimensional variances in workpieces. For holding a load securely without live air pressure, this cylinder is insufficient since the rear screw is only a stop—you would need to specify a SAIL pneumatic lock or an external rod lock. This SAIJ configuration includes a -S magnet, PT ports, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, ensuring seamless dimensional interchangeability with ISO 15552 cylinders.
Quick checklist
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it achieves 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its 170 mm nominal length down to 130 mm. It is a travel stop for setting end positions, not a lock, and does not hold the load without continuous air pressure.
