About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-50S
The AirTAC SAIJ32X165-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 115-165 mm usable travel window, allowing you to dial back the 165 mm nominal stroke by up to 50 mm during machine commissioning. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers a 345 N pull force at 0.5 MPa.
The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports CMSE reed and DMSE electronic solid-state switches for exact end-position detection. The rear adjuster acts purely as a travel stop for fine-tuning end positions without adding external stops, but it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-50S Is Used
Machine Setup Tuning
Dial in the exact 115 to 165 mm end-position during commissioning without machining external stoppers or changing the cylinder.
Product Changeover
Quickly adjust the travel window on packaging lines when handling different carton sizes, ensuring precise stops on the fly.
Assembly Positioning
Fine-tune the retract stroke on automated fixtures to accommodate part tolerances, relying on the integrated magnet for sensor feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-50S the Right Cylinder?
Choose this 32 mm bore when your application requires a 345 N pull force at 0.5 MPa and on-the-fly stroke tuning. If your setup demands higher thrust, stepping up to the 40 mm bore yields a 528 N pull force at the same pressure. The adjustable stroke is ideal for product changeovers where the exact end-position varies, saving you from swapping out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 165 mm stroke, 50 mm adjustment range, PT port thread, and the -S magnet requirement. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Because the 165 mm stroke is relatively short, side-load risks are minimal, but always ensure the M10x1.25 rod thread is aligned to prevent binding.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ32BX165-50S FAQ
The cylinder has a 165 mm nominal stroke, but the rear adjuster allows you to shorten the effective travel by up to 50 mm, creating a usable window of 115 to 165 mm.
Because this model includes a magnet (-S), it works seamlessly with AirTAC CMSE reed switches and DMSE electronic solid-state sensors mounted in the dual-side barrel grooves.
