About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-50
The AirTAC SAIJ32X260-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 50 mm adjustment range, allowing you to fine-tune the effective travel anywhere between 210 and 260 mm during commissioning. Delivering 563 N of push force at 0.7 MPa, this 32 mm bore actuator is built with a SUS304 stainless steel rod for superior corrosion resistance.
Unlike a fixed-stroke SAI, the external stopper screw lets you dial in exact end positions without adding external stops or swapping the cylinder. The extruded aluminum barrel features sensor grooves on both sides, and fluid supply is routed through a PT G1/8 port. The rear adjuster functions strictly as a travel stop, not a lock, meaning it cannot hold a load without continuous air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-50 Is Used
Product Changeovers
Quickly dial in the 210 to 260 mm travel window when switching between product sizes on a packaging line, avoiding mechanical rebuilds.
End-Position Tuning
Fine-tune the retract stroke during machine commissioning to achieve exact material placement without adding external stopper blocks.
Corrosive Environments
Leverage the SUS304 stainless steel rod for light-duty positioning tasks in food processing or chemical areas prone to moisture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-50 the Right Cylinder?
Choose this 32 mm bore when your application requires 563 N of push force at 0.7 MPa but demands variable end-positioning. If your setup needs less force, stepping down is not an option in this size class, but moving up to a 40 mm bore yields 879 N at 0.7 MPa. The adjustable stroke is ideal for product-size changeovers on a line, whereas a standard SAI cylinder is better suited for fixed repetitive motions. For load-holding without live air pressure, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 260 mm nominal stroke, 50 mm adjustment, PT G1/8 port, and your required mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Since the 260 mm stroke is relatively long for this compact bore, ensure adequate external guidance to prevent excessive side-loading on the rod.
Quick checklist
- ✓ 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 SAIJ32BX260-50 FAQ
At 0.7 MPa, this 32 mm bore cylinder provides 563 N of push force and 345 N of pull force. It operates at a speed range of 30-800 mm/s.
The rear adjuster acts as a stopper screw that lets you mechanically shorten the stroke by up to 50 mm, providing an effective travel window of 210 to 260 mm. It is a travel stop, not a locking mechanism.
