About the Airtac SAI80 Standard Air Cylinder SAI80BX35S
The AirTAC SAI80X35-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation. It provides a substantial push force of 2513 N at 0.5 MPa, extending just 35 mm to move heavy loads within confined machinery. The extruded aluminum barrel design eliminates tie rods, ensuring a clean exterior that resists mechanical fouling.
Configured specifically for harsh or washdown environments, this unit features a SUS304 stainless steel piston rod (material code B) and PT tapered port threads. The integrated -S magnet allows direct mounting of CMSE or DMSE sensor switches directly into the dual barrel grooves, streamlining automation feedback without requiring additional brackets.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX35S Is Used
Heavy-Duty Clamping
Generates 2513 N of clamping force at just 0.5 MPa, securing heavy automotive or steel components during machining operations.
Pallet Diverting
Extends rapidly across a 35 mm gap to redirect heavy pallets on high-throughput packaging and material handling conveyor lines.
Short-Stroke Pressing
Applies consistent downward pressure for inserting bearings or pins into housings without requiring a full hydraulic press setup.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX35S the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm variant upgrades thrust from 1559 N to 2513 N at 0.5 MPa, whereas stepping up to a 100 mm bore yields 3927 N. The 35 mm stroke is optimal for rapid clamping or lifting tasks where full extension speed matters more than travel distance.
Because standard SAI cylinders lack a mechanical lock, exhaust or pressure loss will cause the piston to drift. If the application must hold a suspended load safely without live air pressure, specify the SAIL variant with an air-released lock or utilize an external rod lock. For direct retrofits, match the 80 mm bore, 35 mm stroke, PT G3/8 ports, and required mounting accessories like FA flanges or TC trunnions.
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.
