About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-75S
The AirTAC SAIJ32X900-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 825-900 mm without adding external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
This specific configuration uses a SUS304 stainless steel rod (material code B) for superior corrosion resistance and features a PT tapered port thread. The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear adjuster acts purely as a travel stop to set deceleration and end positions, so it will not hold a load safely without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-75S Is Used
Variable End-Position Tuning
Dial in the exact retract distance within the 825-900 mm window during machine commissioning to accommodate different material lengths without changing hardware.
Product Size Changeover
Quickly adjust the stroke stop on packaging or sorting lines to handle varying box dimensions on the fly, minimizing downtime between production runs.
Light-Duty Positioning
Leverage the 402 N push force at 0.5 MPa for precise component placement and ejection tasks where exact end-stop control is critical.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-75S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your machine setup requires variable end-stops or frequent product changeovers rather than a fixed-stroke SAI model. If your application demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because this 900 mm stroke is long and unsupported, the 12 mm rod and M10x1.25 thread still require an external guide to prevent excessive side-loading and binding.
For a true ISO 15552 replacement match, verify the 32 mm bore, 900 mm nominal stroke, 75 mm adjustment range, PT port thread, and the -S magnet option. Keep in mind that neither the rear adjuster nor the adjustable air cushions function as a lock; if you need true load-holding without continuous air pressure, consider the SAIL or BSAI series instead.

- ✓ 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 SAIJ32BX900-75S FAQ
The rear adjuster screw acts as an external stop that lets you shorten the effective stroke by up to 75 mm. This provides a usable travel window of 825-900 mm, allowing you to fine-tune the end position at commissioning without swapping the cylinder.
At 0.5 MPa operating pressure, it generates 402 N of push force and 345 N of pull force. It can reach a maximum thrust of 82 kgf at 1.0 MPa.
