The AirTAC SAI50 Standard Cylinder SAI50AX135 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 135mm 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 SAI50X135 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 135 mm stroke is a non-standard, made-to-order length, providing exact travel for specialized assembly operations.
This actuator features a SUS420J2 stainless steel piston rod for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes dual sensor grooves, allowing for flexible mounting of CMSE or DMSE switches if a magnet is added later.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
The exact 135 mm stroke is ideal for specialized jigs requiring precise travel without the slack of a longer standard cylinder.
Provides 982 N of push force at 0.5 MPa, easily handling medium-weight cartons on a sorting line.
The SUS420J2 stainless steel rod offers reliable performance in humid or lightly corrosive industrial environments.
If your application requires less thrust, stepping down to the 40 mm bore yields 628 N at 0.5 MPa. For heavier payloads, the 63 mm bore provides 1559 N. Since this 135 mm stroke is custom, expect a slightly longer lead time.
This model uses a PT tapered port thread. Because a standard SAI cylinder relies on air pressure to maintain its position, it will drift if pressure is lost; for fail-safe load holding, consider the SAIL pneumatic lock variant. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, as a genuine ISO 15552 profile cylinder, its mounting interface is dimensionally interchangeable with other ISO 15552 cylinders, allowing for seamless direct replacement.
