About the Airtac SAI50 Standard Cylinder SAI50BX70
The AirTAC SAI50X70 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force and 825 N of pull force at 0.5 MPa. Its 70 mm stroke provides a compact extension distance well-suited for mid-range actuation tasks. Because it adheres to standardized mounting dimensions, it serves as a direct replacement for other ISO 15552 profile cylinders.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a standard piston magnet. For higher temperature environments up to 150 C, the standard TPU seals can be swapped for Viton (H) alternatives.

Where the Airtac SAI50 Standard Cylinder SAI50BX70 Is Used
Clamping Mechanisms
Provides 982 N of clamping thrust at 0.5 MPa for securing medium-sized metal or composite parts during machining operations.
Package Diverting
Actuates short-stroke diverter arms on packaging lines, utilizing the 70 mm extension to redirect products efficiently.
Gate Control
Operates small access gates or machine guarding doors where the SUS304 rod ensures longevity in mildly corrosive industrial settings.
Is the Airtac SAI50 Standard Cylinder SAI50BX70 the Right Cylinder?
Select this 50 mm bore when a 32 mm bore (providing 402 N at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N at 0.5 MPa) would be physically oversized. The 70 mm stroke is ideal for short, rapid movements. Since this model is supplied without a magnet (-S), position sensing requires external limit switches rather than embedded cylinder sensors.
Keep in mind that standard double-acting cylinders drift when air pressure is removed. If your application requires the piston to hold its position against a load during an air loss or emergency stop, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
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 SAI50BX70 FAQ
