About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-50
The AirTAC SAIJ32X170-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 170 mm travel by up to 50 mm. This creates a precise 120 to 170 mm usable window, enabling exact end-position tuning at commissioning without adding external stops. It delivers 402 N of push force at 0.5 MPa and reaches a maximum of 724 N at 0.9 MPa.
Equipped with a SUS304 stainless steel rod and PT tapered ports, this 32 mm bore unit runs at 30-800 mm/s. The extruded aluminum barrel includes dual sensor grooves, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-50 Is Used
Machine Setup
Dial in the exact 120 to 170 mm end-position during commissioning to perfect part ejection without swapping out the physical cylinder.
Product Changeover
Quickly adapt the stroke window on packaging lines when handling slightly different carton sizes, reducing downtime between production runs.
Variable End Stops
Use the 50 mm rear adjustment range to fine-tune the retract position on testing fixtures, ensuring components meet precise dimensional checks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-50 the Right Cylinder?
Select this 32 mm bore model when your setup requires a variable end-stop within a 120-170 mm range, making it more practical than a fixed-stroke SAI cylinder for product changeovers. If your application needs greater thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. To replace an ISO 15552 cylinder, match the 170 mm stroke, 50 mm adjustment, PT ports, and the chosen mounting accessory.
Because the 170 mm stroke is relatively short for the 32 mm bore, side-load risks are minimal, though the 12 mm rod and M10x1.25 thread handle standard loads well. For any load-holding requirements without continuous air pressure, this cylinder is insufficient; consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a lock.
Quick checklist
- ✓ 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 SAIJ32BX170-50 FAQ
This 32 mm bore cylinder generates 402 N of push force and 345 N of pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster screw lets you shorten the 170 mm nominal stroke by up to 50 mm, providing a usable travel window of 120 to 170 mm for fine-tuning the retract end position.
