About the Airtac SAI100 Standard Air Cylinder SAI100BX65S
The AirTAC SAI100X65-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning, delivering a robust 3927 N of push force at 0.5 MPa. Its 65 mm stroke provides a compact extension distance for high-force clamping or short-stroke ejection tasks in confined machinery.
Configured with a highly corrosion-resistant SUS304 stainless steel rod (material code B) and standard PT tapered port threads, this variant is built for harsh environments. The integrated magnet (-S) enables direct mounting of CMSE or DMSE sensor switches along the extruded aluminum barrel grooves for precise end-of-stroke detection.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX65S Is Used
Heavy-Duty Stamping
Provides the 3927 N push force required to seat bearings or form sheet metal components in compact press setups.
Short-Stroke Clamping
Ideal for securing large, heavy workpieces during machining operations where a short 65 mm travel distance is needed.
Part Ejection
Delivers rapid, high-force ejection of finished metal parts from tight mold cavities or machining centers.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX65S the Right Cylinder?
Select this 100 mm bore when 80 mm (2513 N at 0.5 MPa) lacks the necessary thrust for your heavy fixtures, but you want to avoid the physical mass and larger port sizing of the 125 mm bore. The 65 mm stroke is optimal for short, powerful movements. For longer travel requirements exceeding 300 mm, consider transitioning to a guided cylinder to prevent rod-bearing bending under side loads.
As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, matching standard mounting foot, flange, and trunnion accessories. Note that the standard adjustable air cushions only decelerate the piston near stroke end; if the application requires holding a load without live air pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant.
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 SAI100 Standard Air Cylinder SAI100BX65S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force.
Yes, the SAI100X65-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can reuse existing mounting accessories and footprint dimensions, provided the port size (G1/2) and stroke match.
