About the Airtac SAI32 Standard Cylinder SAI32X70
The AirTAC SAI32X70 is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 563 N at 0.7 MPa, this 32 mm bore unit with a 70 mm stroke is tailored for precise, short-distance movements. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior that resists debris accumulation.
Equipped standard with a carbon steel piston rod and PT tapered port threads, it integrates seamlessly into existing pneumatic setups. For high-temperature environments up to 70 C, the standard TPU seals handle typical demands, while operators requiring position feedback can specify the -S magnet option to utilize CMSE or DMSE switches in the dual sensor grooves.

Where the Airtac SAI32 Standard Cylinder SAI32X70 Is Used
Component Clamping
Ideal for securing small machined parts during milling or drilling, utilizing its 563 N push force to hold workpieces firmly without deformation.
Package Diverting
Provides rapid actuation for diverting small cartons on packaging lines, where the 70 mm stroke offers fast response times and compact footprint.
Gate Control
Actuates small pneumatic gates and valves in material handling systems, benefiting from the adjustable air cushions to prevent end-of-stroke impact.
Is the Airtac SAI32 Standard Cylinder SAI32X70 the Right Cylinder?
Selecting the SAI32X70 is optimal when application forces hover around 500 N; if your load requires less than 400 N, stepping down to a 20 mm bore saves space, while loads exceeding 800 N warrant the 40 mm bore delivering 879 N at 0.7 MPa. This 70 mm stroke provides quick actuation without the side-load risks inherent to longer extensions.
As a dimensionally interchangeable ISO 15552 component, it serves as a direct replacement for other standard profile cylinders. Match your mounting hardware using FA or LB accessories, ensure your PT port fittings align with the G1/8 thread, and add the -S magnet if sensor tracking is required. Note that this standard cylinder relies on air pressure to maintain position; it will drift if pressure is lost, so use a SAIL variant if mechanical locking is needed.
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 SAI32 Standard Cylinder SAI32X70 FAQ
