About the Airtac SAI50 Standard Cylinder SAI50BX50
The AirTAC SAI50X50 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 50 mm stroke is ideal for short-travel clamping, gating, and compact ejection tasks. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that speeds up machine integration and sensor placement.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in wet or chemically exposed settings. It uses PT tapered port threads, and because no magnet is specified, it is optimized for purely mechanical actuation without sensor feedback. The standardized ISO 15552 mounting dimensions ensure it drops directly into existing footprints without requiring structural redesign.

Where the Airtac SAI50 Standard Cylinder SAI50BX50 Is Used
Short-Stroke Clamping
Provides reliable 982 N holding force at 0.5 MPa for securing workpieces during light machining and assembly operations.
Package Diverting
Actuates routing gates and pusher arms on packaging lines where a compact 50 mm stroke is sufficient to redirect product flow.
Material Ejection
Delivers rapid, repeatable ejection of finished parts from press beds, utilizing the durable SUS304 rod to withstand repetitive impact.
Is the Airtac SAI50 Standard Cylinder SAI50BX50 the Right Cylinder?
Choose this 50 mm bore when a 40 mm bore (yielding 628 N at 0.5 MPa) is too weak, but a 63 mm bore (1559 N) is physically oversized. For this 50 mm stroke, side-load stress on the rod bearing is minimal, making it highly reliable for rigid short-throw applications. If your workflow demands position holding upon air loss, note that standard air cushions only decelerate the piston at stroke end; you must specify an SAIL locking variant or an external pilot-operated check valve for secure load holding.
To match this cylinder exactly for a replacement, confirm the 50 mm bore, 50 mm stroke, PT G1/4 port, and your required mounting accessory (such as an FA flange or LB foot). Since this unit lacks a magnet, do not expect CMSE or DMSE sensors to function; if proximity detection is needed, select an SAI50X50-S model instead.
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 SAI50 Standard Cylinder SAI50BX50 FAQ
The SAI50X50 generates 982 N of push force and 825 N of pull force at a 0.5 MPa operating pressure, scaling up to 1374 N push at 0.7 MPa.
Yes. The SAI50X50 is dimensionally interchangeable per ISO 15552, allowing it to direct replace other profile cylinders with a 50 mm bore and G1/4 ports without modifying the mounting footprint.
