About the Airtac SAID50 Double Rod Cylinder SAID50X45S
The AirTAC SAID50X45-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and a 45mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal push and pull force of 825N at 0.5 MPa. A rod protrudes from both end covers, allowing you to mount the primary workpiece on one side and a secondary cam or position flag on the opposite rear end.
This specific configuration includes a -S magnet for position sensing and uses standard carbon steel rods. The extruded aluminum barrel integrates sensor grooves on both sides, accepting AirTAC CMSE reed and DMSE solid-state switches. Fluid supply is via tapered PT ports, and the unit features adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAID50 Double Rod Cylinder SAID50X45S Is Used
Symmetric Transfer
Drives a transfer shuttle where the equal 825N extend and retract forces ensure consistent timing and smooth motion shifting parts between two stations.
Anti-Rotation Slide
The twin through-rods provide high torsional resistance, guiding a precision slide or gripper carriage without the yaw instability of a single rod.
Rear-Cam Actuation
The protruding rear rod operates a secondary mechanism or mechanical limit flag, while the front rod executes the primary 45mm clamping or positioning task.
Is the Airtac SAID50 Double Rod Cylinder SAID50X45S the Right Cylinder?
Choose this 50mm bore when an application requires balanced 825N thrust in both directions, stepping up from the 40mm bore (528N) for higher capacity, or down from the 63mm bore (1402N) when space is constrained. A double-rod design is selected over a single-rod SAI when the mechanism demands superior anti-rotation guidance, dual-side tooling, or rear-rod limit sensing. Ensure your mounting hardware uses the SAID accessory set: Basic, FA, LB, TC, FTC, TCM1, or TCM2, as FB, CA, CB, and CR are single-rod exclusions.
This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 double-rod cylinders. Note that a plain SAID does not hold its load if air pressure is lost; a SAIL or BSAID lock variant is required for pneumatic position holding. The 45mm stroke is well below the side-load threshold, so standard rod bearing support is sufficient.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAID50 Double Rod Cylinder SAID50X45S FAQ
Because the double-rod design creates equal annulus areas on both sides of the piston, the output force is identical in both directions: 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa.
Yes, the SAID50X45-S is dimensionally interchangeable per ISO 15552 mounting dimensions. You can use it as a drop-in replacement for other ISO 15552 double-rod profile cylinders, provided your port and mounting accessory match.
