About the Airtac SAID32 Double Rod Cylinder SAID32X45
The AirTAC SAID32X45 is a double-acting, double-rod pneumatic cylinder built on the ISO 15552 profile standard, featuring a non-standard 45mm stroke made-to-order for specific spatial requirements. Because a rod exits both end covers, the effective piston area is identical in both directions, yielding an equal extend and retract force of 483N at 0.7 MPa. The carbon steel rod and PT tapered port threads are standard, while the extruded aluminum barrel includes sensor grooves on both sides.
This twin-rod architecture is designed for applications requiring dual-side guidance or anti-rotation control. You can mount the primary workpiece on the front rod and affix a cam or position flag to the rear protruding rod. Note that the overall length is longer than a single-rod SAI variant, requiring additional rear clearance. The adjustable air cushions at both ends decelerate the piston near stroke end but do not lock the load if air pressure is lost.

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.

Where the Airtac SAID32 Double Rod Cylinder SAID32X45 Is Used
Symmetric Force Transfer
Push and pull identical loads at 483N without speed variation, utilizing the equal annular area on both sides of the 32mm piston.
Anti-Rotation Slides
Prevent rod twisting during vertical or horizontal movement by utilizing the twin-rod design for inherent dual-side guidance.
Rear-Rod Cam Actuation
Drive the primary tool on the front rod while using the rear protrusion to mechanically trip an external limit valve or cam.
Is the Airtac SAID32 Double Rod Cylinder SAID32X45 the Right Cylinder?
Choose this 32mm bore double-rod cylinder when your mechanism requires equal push and pull forces (483N at 0.7 MPa) and inherent anti-rotation guidance that a single-rod SAI cannot provide. If your application needs less force, stepping down is not an option within the SAID range, but stepping up to a 40mm bore yields 739N at 0.5 MPa. The 45mm stroke is non-standard and made-to-order; ensure your design accommodates this exact length. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants found on single-rod models.
Because this is a non-standard 45mm stroke, verify the exact overall dimensions with the datasheet before finalizing your CAD layout. The cylinder lacks a magnet (-S), so position sensing requires external switches or a rear-rod cam rather than embedded CMSE or DMSE sensors. If the machine must hold a load vertically without continuous air pressure, a plain SAID will drift; you should specify an SAIL (air-released lock) or BSAID (clamp-lock) cylinder instead.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID32 Double Rod Cylinder SAID32X45 FAQ
The double-rod design means the push and pull forces are equal. It provides 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa in both directions.
Yes, it is dimensionally interchangeable per ISO 15552. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR styles.
