About the Airtac SAI32 Standard Cylinder SAI32X850S
The AirTAC SAI32X850-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and an 850mm stroke. Because this stroke exceeds the standard 500mm limit for this bore, it is manufactured as a non-standard, made-to-order unit. It generates 563N of push force and 345N of pull force at a 0.5MPa operating pressure, making it suitable for extended reach automation.
This model includes an integrated magnet for use with CMSE and DMSE sensor switches, which ride securely in the extruded aluminum barrel's dual sensor grooves. The piston rod is constructed from standard carbon steel, and the body utilizes a tie-rod-less profile design that conforms strictly to ISO 15552 dimensional interchangeability standards.

Where the Airtac SAI32 Standard Cylinder SAI32X850S Is Used
Extended Reach Ejection
Ideal for pushing parts out of long machining centers or conveyor lines where a standard 500mm stroke falls short.
Material Transfer
Transfers lightweight components across wide conveyor gaps, utilizing the 563N push force at 0.7MPa effectively.
High Bay Diversion
Actuates diverter arms in high-bay storage systems, taking advantage of the long 850mm travel distance.
Is the Airtac SAI32 Standard Cylinder SAI32X850S the Right Cylinder?
When sizing this cylinder, consider stepping up to a 40mm bore if your application requires greater thrust, as the 40mm version provides 628N of push force at 0.5MPa compared to the 32mm's 402N. Conversely, if the extended 850mm stroke is unnecessary, dropping to a standard 500mm stroke reduces cost and lead time.
Because the 850mm stroke is well over 300mm, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, pair this cylinder with an external guide rail or use a fully guided cylinder for heavy offset loads. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If pressure is lost, the rod will drift. Use a SAIL variant with an air-released lock or a BSAI clamp-lock for position holding. For direct replacements, match the 32mm bore, 850mm stroke, PT G1/8 port, and the -S magnet option.
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 SAI32X850S FAQ
