The AirTAC SAI50 Standard Cylinder SAI50AX290S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 290mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI50X290-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 290 mm stroke provides the extended travel needed for mid-range material handling and automated positioning tasks.
This variant features a SUS420J2 stainless steel piston rod for superior corrosion resistance compared to standard carbon steel. The integrated magnet (-S) enables seamless position detection using CMSE or DMSE switches mounted directly into the dual sensor grooves on the extruded aluminum barrel.

Extends 290 mm to push medium-weight cartons off a main conveyor belt with 982 N of thrust at 0.5 MPa.
Drives a machined part into a fixture using precise CMSE sensor feedback to confirm proper seating depth.
Pushes standardized totes or trays onto a waiting pallet at 30-800 mm/s operating speeds.
Choose this 50 mm bore when a 40 mm bore (628 N at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (1559 N at 0.5 MPa) would be physically oversized. Because the 290 mm stroke creates an extended unsupported rod length, external guides or a dedicated guided cylinder are recommended to prevent rod-bearing bending under side loads.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement matching the 50 mm bore, 290 mm stroke, PT G1/4 port, and standard mounting accessories like FA flanges or TC trunnions. Note that air pressure is required to maintain position; if the load must be held during pressure loss, specify the SAIL lock variant.
Quick checklist
This double-acting cylinder provides 982 N of push force and 825 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 1374 N.
Yes, this specific model uses a SUS420J2 stainless steel piston rod (material code A) which offers better corrosion resistance than standard carbon steel.
