About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-50
The AirTAC SAIJ32X700-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 700mm nominal stroke that can be fine-tuned down by up to 50mm, creating a precise 650-700mm usable travel window for exact end-position calibration.
This variant utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE reed or DMSE electronic switches if a magnet is added later.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-50 Is Used
Product Changeover
Dial in the 650-700mm stroke window during format size changes on packaging lines without swapping out the entire cylinder.
Variable End Stops
Adjust the retract position on the fly for diverter gates handling varying package lengths on a conveyor system.
Machine Setup
Fine-tune the end-of-stroke position during commissioning to perfectly time machine operations without adding external physical stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-50 the Right Cylinder?
Choose this 32mm bore when an application requires 402N push force at 0.5 MPa but demands variable end-stops for product changeovers; if you need greater thrust, stepping up to the 40mm bore yields 628N. Because the 700mm stroke is quite long relative to the 12mm rod diameter, an external guide is highly recommended to prevent excessive side-loading and rod deflection.
The rear adjuster screw acts strictly as a travel stop to decelerate the load alongside the standard air cushions, but it will not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. This model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX700-50 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 50mm from the 700mm nominal length, providing a 650-700mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
