About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-50S
The AirTAC SAIJ32X270-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 270 mm travel by up to 50 mm. This creates a usable 220-270 mm end-position window, letting you fine-tune the retract stop at commissioning without adding external stops or swapping the cylinder. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches. The extruded aluminum barrel includes sensor grooves on both sides. It uses a PT G1/8 port and M10x1.25 rod thread, and relies on variable air cushions at both ends to decelerate the load.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-50S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 220 and 270 mm during machine commissioning to accommodate varying material thicknesses without replacing the actuator.
Product Changeover
Quickly adjust the stroke end-position on packaging lines when switching between different product sizes, minimizing downtime and avoiding external stop hardware.
Corrosive Assembly Tasks
Leverage the SUS304 stainless steel rod in light-duty assembly or washdown environments where precise positioning and material rust resistance are both required.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-50S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke model when your application requires precise end-position tuning during machine setup or product changeover, rather than a fixed-stroke SAI cylinder. If you need higher thrust, stepping up to a 40 mm bore increases the push force to 628 N at 0.5 MPa; conversely, smaller bores reduce the footprint. Because the stroke is 270 mm, the 12 mm rod and M10x1.25 thread have limited side-load capacity, so an external guide rail is recommended for heavy lateral loads.
For ISO 15552 replacement matching, specify: 32 mm bore, 270 mm stroke, 50 mm adjustment range, PT G1/8 port, SUS304 (B) rod material, magnet included (-S), and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For true load-holding without continuous air, consider an AirTAC SAIL or BSAI 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 SAIJ32BX270-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can achieve up to 724 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 270 mm down by up to 50 mm, creating a 220-270 mm usable window. It only sets the end position and does not lock the load without continuous air pressure.
