The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 155mm 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 SAIJ32X155-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 105 to 155 mm. Delivering 402 N of push force at 0.5 MPa, it is equipped with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread for reliable pneumatic sealing.
This extruded aluminum profile cylinder includes variable air cushions at both ends to manage end-of-stroke impact. The rear adjustment mechanism acts purely as a mechanical stop to fine-tune the retract position during commissioning; it does not lock or hold the load without live air pressure.

Dial in the exact retract distance from 105 to 155 mm during packaging format changes without adding external physical stops to the machine frame.
Fine-tune the end-of-stroke position during initial commissioning to dial out mechanical play or account for sensor bracket offsets.
Adjust the travel limit on the fly for testing different component heights or varying process parameters in a laboratory environment.
Choose this 32 mm bore model when an application requires precise end-position tuning without swapping cylinders, offering a 50 mm adjustment range that steps down from the 40 mm bore's 628 N push force. For load-holding without continuous air pressure, consider the AirTAC SAIL or BSAI series, as the SAIJ adjuster is strictly a travel stop.
To replace an ISO 15552 cylinder, match the 32 mm bore, 155 mm stroke, PT port thread, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Because this unit lacks a magnet, it does not support CMSE or DMSE sensors; if position feedback is needed, select an -S designated model.
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. The standard speed range is 30-800 mm/s, driven by a G1/8 port.
The rear adjuster screw allows you to shorten the effective travel from the nominal 155 mm down to 105 mm, providing a 50 mm tuning window. This stopper sets the retract end position but does not hold the load if air pressure is removed.
