About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-50S
The AirTAC SAIJ32X750-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 700-750mm usable travel window by allowing you to dial back the nominal 750mm stroke by up to 50mm. This bore generates 563N of push force at 0.7 MPa and operates at speeds of 30-800 mm/s.
Equipped with a SUS304 stainless steel rod, it handles corrosive environments better than standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-50S Is Used
Changeover Calibration
Dial in the exact end-stop from 700 to 750mm during product size changeovers without adding external physical stops to the machine frame.
Variable Positioning
Fine-tune the retract distance on a packaging conveyor to accommodate different package widths on the fly during line setup.
Sensor Setup
Leverage the dual-side sensor grooves and built-in magnet to easily set DMSE electronic switch trip points alongside the mechanical stroke limit.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-50S the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your machine setup requires fine end-position tuning during commissioning or product changeover without swapping out the entire actuator. If your application requires more thrust, stepping up to the 40mm bore yields 879N of push force at 0.5 MPa. For load-holding without continuous air pressure, this standard SAIJ is insufficient; consider the SAIL air-released lock or BSAI clamp-lock series instead.
This SAIJ32X750-50-S configuration features a PT tapered port, a 12mm rod with an M10x1.25 thread, and a built-in magnet for position sensing. Because the stroke is 750mm, the extended rod is highly susceptible to side-loading; an external guide is strongly recommended to prevent premature seal wear. It supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.

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 SAIJ32BX750-50S FAQ
The rear adjuster is a mechanical stop that lets you shorten the effective travel from 750mm down to 700mm. It is used for fine-tuning end positions at commissioning but does not lock or hold the load without live air pressure.
At 0.7 MPa operating pressure, the SAIJ32X750-50-S provides 563N of push force and 345N of pull force. The maximum operating pressure is 1.0 MPa.
