The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 100mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI40X100 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 100 mm stroke provides an optimal mid-range extension for general automation tasks. The extruded aluminum barrel design omits tie-rods, presenting a clean exterior that speeds up assembly and maintenance.
This configuration features a standard carbon steel piston rod and a PT tapered G1/4 port thread. Because it lacks a factory magnet, position sensing requires external limit switches. For high-temperature environments up to 70 C, the standard TPU seals handle the job, though Viton H seal variants are available across the SAI family for more extreme thermal demands.

Secures medium-weight machined parts during milling with 879 N of clamping force at 0.7 MPa.
Extends 100 mm to push cartons off a sorting line with rapid 30-800 mm/s actuation speeds.
Cycles lightweight access doors and machine guards using a durable carbon steel rod.
Select the 40 mm bore when an application demands more power than a 32 mm bore (402 N at 0.5 MPa) but does not warrant the bulk of a 50 mm bore (982 N at 0.5 MPa). At a 100 mm stroke, the rod bearing handles side loads effectively without requiring external guides. To mount this unit, utilize standard ISO 15552 accessories like FA flanges or LB foot brackets. Specify a -S suffix if you later require internal CMSE or DMSE sensors.
Remember that standard air cushions only decelerate the piston near the stroke endpoints; they do not lock the rod. If your fixture loses pneumatic pressure, the load will drift. Use a SAIL variant with an air-released lock or an external pilot check valve for fail-safe position holding.
Quick checklist
The SAI40X100 generates 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N.
Yes. The SAI40X100 is dimensionally interchangeable per ISO 15552, meaning it matches the mounting interface and footprint of other standard ISO 15552 profile cylinders.
