The AirTAC SAI63 Standard Cylinder SAI63X145 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 145mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI63X145 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa and 1402 N of pull force. Its 145 mm stroke provides the precise mid-range travel needed for clamping, lifting, and indexing tasks. The extruded aluminum barrel eliminates tie-rods, resulting in a cleaner profile that drops directly into standardized ISO 15552 mounting footprints.
This configuration features a standard carbon steel piston rod and PT tapered port threads. Because no magnet is specified, it operates without sensor tracks; add the -S suffix if you need CMSE or DMSE switches for position detection. For operations requiring position holding without continuous air pressure, consider the SAIL variant.

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.
Provides 1559 N of secure clamping force at 0.5 MPa for holding heavy machined parts during milling or drilling operations.
Utilizes the 145 mm stroke to push cartons smoothly between adjacent conveyor lanes in high-speed sorting facilities.
Delivers rapid ejection of molded parts from press beds, using adjustable cushions to absorb kinetic energy at stroke end.
Select this 63 mm bore when a 50 mm cylinder (providing 982 N at 0.5 MPa) lacks the power to move your load, but an 80 mm bore (2513 N) would be excessive and consume too much air volume. The 145 mm stroke hits a sweet spot for compact machinery. To match an existing installation, verify the G3/8 port, M16x1.5 rod thread, and ISO 15552 mounting accessories like FA flanges or TC trunnions.
Since this is a standard double-acting actuator, it will drift if air pressure is lost or the control valve is centered. The adjustable air cushions at both ends only decelerate the piston near the stroke ends to prevent impact damage; they do not lock the load. Use an external pilot-operated check valve if you need static holding power.
Quick checklist
At 0.5 MPa operating pressure, this cylinder generates 1559 N of push force and 1402 N of pull force. If you increase pressure to 0.7 MPa, the push force rises to 2182 N.
Yes. The SAI63X145 is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts using standard FA, LB, or TC accessories, provided your setup matches the G3/8 port and M16x1.5 rod thread.
