The AirTAC SAI63 Standard Cylinder SAI63X170S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 170mm 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 SAI63X170-S is a double-acting ISO 15552 profile cylinder engineered for mid-range automation tasks. Delivering a push force of 1559 N at 0.5 MPa, this 63 mm bore unit paired with a 170 mm stroke hits a sweet spot for moving substantial jigs or clamping heavy workpieces. Its extruded aluminum barrel omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes a piston magnet (-S) for position detection, allowing seamless integration with CMSE or DMSE reed switches along the dual sensor grooves. It features a standard carbon steel piston rod and utilizes a PT tapered port thread (G3/8) for reliable pneumatic sealing. For environments requiring higher heat resistance, the standard TPU seals can be swapped for Viton (H) or NBR (N) variants.

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 clamping thrust at 0.5 MPa to secure heavy metal castings during CNC machining operations.
Uses the 170 mm stroke to push heavy pallets smoothly onto secondary processing lines without overshooting.
Cycles rapidly at up to 800 mm/s to eject formed parts from hydraulic presses, utilizing the integrated magnet for timing confirmation.
Selecting this 63 mm bore makes sense when a 50 mm cylinder (offering 982 N push at 0.5 MPa) lacks the thrust for your payload, but an 80 mm unit (2513 N) would be physically oversized and consume excess air. The 170 mm stroke provides ample travel for indexing parts without the extreme space requirements of longer strokes. Because the stroke is under 300 mm, rod-bearing bending stress is minimal, though external guides should still be used for heavy off-center loads.
As a true ISO 15552 cylinder, this model is dimensionally interchangeable with other standard profile cylinders of the same bore. To complete your assembly, match the 63 mm bore, 170 mm stroke, G3/8 PT port, and your desired mounting accessory (such as an LB foot or TC trunnion). Note that this standard cylinder relies on adjustable air cushions at both ends to decelerate the piston; it does not hold position pneumatically. If your application requires the load to remain fixed during a pressure drop, specify the SAIL lock or BSAI clamp-lock variant instead.
Quick checklist
At a standard operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X170-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mountings matching the 63 mm bore and 170 mm stroke, provided your port and accessory clearances align.
