About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-75S
The AirTAC SAIJ32X200-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 200 mm stroke that can be fine-tuned backward by up to 75 mm, yielding a usable travel window of 125-200 mm. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. This variant includes a magnet for position sensing and features a SUS304 stainless steel rod for superior corrosion resistance.
The rear adjuster acts purely as a mechanical stop to tune the retract end-position during commissioning or product changeovers without swapping the cylinder. It does not lock the load; for holding position without live air pressure, an external pilot-operated check valve or a related SAIL lock cylinder is required. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered ports are G1/8.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-75S Is Used
Product Size Changeover
Dial in the retract distance from 125 to 200 mm on the fly when adapting a packaging line to different carton sizes without changing hardware.
End-Stop Calibration
Fine-tune the final resting position of a pick-and-place tool during machine commissioning to avoid mechanical crashes and ensure precise placement.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable, repeatable clamping in light chemical washdown areas where carbon steel would degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-75S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your setup requires precise end-position tuning across a 125-200 mm window. If your application needs less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore increases push force to 628 N at 0.5 MPa. The integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors for exact position feedback. Because this is a 200 mm stroke, ensure external guiding if side loads are present.
The SAIJ mounting set is a reduced subset of the standard SAI line, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 options while omitting FB, CA, CB, and CR. To match this exact ISO 15552 interchangeable replacement, specify: 32 mm bore, 200 mm stroke, 75 mm adjustment, PT G1/8 port, SUS304 (B) rod material, and the -S magnet.

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 SAIJ32BX200-75S FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 75 mm. This creates a usable travel window of 125 to 200 mm, enabling fine-tuning of the end position without adding external stops.
At 0.5 MPa operating pressure, the SAIJ32X200-75-S generates 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
