The AirTAC SAID32 Double Rod Cylinder SAID32AX950 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 950mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAID32X950 is a double-acting, double-rod ISO 15552 profile cylinder engineered for applications requiring symmetric force and dual-side guidance. Because the piston rod exits both end covers, the annulus area is identical on extend and retract, delivering an equal 483 N of thrust and pull at 0.7 MPa. This 950 mm stroke configuration is a non-standard, made-to-order length exceeding the 32 mm bore's 1000 mm maximum standard limit, requiring extra rear-rod clearance.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though position monitoring requires adding a magnet separately. For high-temperature environments up to +70 C, standard TPU seals are used, with Viton H available as an upgrade.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Drives a workpiece between two stations with identical 483 N push and pull force, ensuring consistent acceleration and deceleration profiles across a 950 mm span.
The twin-rod architecture prevents piston rotation during long 950 mm traverses, maintaining precise angular alignment for downstream pick-and-place tooling.
Mounts a physical cam or limit flag on the protruding rear rod end to trigger external mechanical switches, independent of the primary front-side workpiece actuation.
Selecting this 32 mm bore double-rod cylinder makes sense when a mechanism needs equal 483 N force in both directions, anti-rotation guidance, or a rear rod end to drive a secondary cam. If your application requires less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 739 N both ways. Conversely, if you need to hold a load vertically when air pressure is lost, a standard SAID will drift; you should evaluate the SAIL lock or BSAID clamp-lock variants instead.
As a dimensionally interchangeable ISO 15552 component, this cylinder serves as a direct replacement for other standard profile cylinders. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories. Because the 950 mm stroke creates a long unsupported rod, external guide rails are strongly recommended to prevent rod-bearing bending and premature seal wear under side loads.
Quick checklist
Because the rod occupies both sides of the piston, the effective area is equal in both directions. The SAID32X950 generates 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa for both extension and retraction.
Yes, the SAID32X950 is dimensionally interchangeable per ISO 15552 mounting dimensions. It uses the standard profile barrel footprint and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, though it omits FB, CA, CB, and CR brackets found on single-rod variants.
