Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-10
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-10 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.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-10
The AirTAC SAIJ32X170-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 170 mm travel by up to 10 mm. This creates a precise 160-170 mm usable stroke window, enabling exact end-position tuning during commissioning without swapping the barrel or adding bulky external stops. It features a SUS304 stainless steel piston rod and a PT tapered port thread, matching the 32 mm bore's 12 mm rod diameter and G1/8 port size.
Providing 402 N of push force and 345 N of pull force at 0.5 MPa, this compact actuator operates at speeds between 30 and 800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. The rear adjuster acts purely as a travel stop and deceleration aid alongside the standard air cushions, meaning it does not hold the load without live air pressure. For load-holding requirements without continuous pressure, consider the SAIL or BSAI variants.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-10 Is Used
Machine Changeover
Dial in the 160-170 mm stroke window during product size transitions to set exact retraction points without changing hardware.
Variable End-Stop Setup
Use the 10 mm rear adjustment screw to fine-tune the retract position precisely during initial machine commissioning.
Light-Duty Positioning
Leverage the 402 N push force at 0.5 MPa for compact clamping or positioning tasks requiring exact travel limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-10 the Right Cylinder?
Choose this 32 mm bore when your application requires the lower end of the thrust spectrum, delivering 402 N push at 0.5 MPa. If your process demands higher force, stepping up to the 40 mm bore yields 628 N push at the same pressure. The adjustable stroke is specifically beneficial for machine setups requiring variable end-stops or fine-tuning during product changeover, offering flexibility that a fixed-stroke SAI cylinder cannot provide.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 170 mm nominal stroke, 10 mm adjustment range, PT port thread, and standard mounting configuration. The SAIJ series supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because this model lacks the -S magnet suffix, it does not support CMSE or DMSE electronic sensors without modification.

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 Adjustable Cylinder SAIJ32 SAIJ32BX170-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective travel from the 170 mm nominal stroke down to 160 mm. This stopper sets the travel end and decelerates the load, but it does not lock the position without live air pressure.
