About the Airtac SAID100 Double Rod Cylinder SAID100X85S
The AirTAC SAID100X85-S is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives rods out of both end covers, yielding equal extend and retract forces. It generates 3681 N of thrust each way at 0.5 MPa, utilizing the pull-side annulus area for symmetric power.
This 100mm bore unit includes a magnetic piston (-S) for position sensing. The extruded aluminum barrel features dual sensor grooves, accepting AirTAC CMSE reed and DMSE solid-state switches. Standard carbon steel rods and PT threaded ports ensure robust, reliable operation.

Where the Airtac SAID100 Double Rod Cylinder SAID100X85S Is Used
Symmetric Transfer
Drives a workpiece on the front rod and a counterweight or flag on the rear rod, ensuring equal push and pull forces of 3681N at 0.5MPa for balanced automation.
Anti-Rotation Slides
The twin 25mm carbon steel rods exit both ends to guide heavy loads against rotation, preventing binding in precision material handling slides.
Dual-Side Actuation
Operates two separate mechanisms simultaneously from one cylinder, using the rear rod end to drive a secondary cam or tooling station.
Is the Airtac SAID100 Double Rod Cylinder SAID100X85S the Right Cylinder?
Choose this 100mm bore when an application demands symmetric force and anti-rotation guidance that a single-rod SAI cannot provide. Stepping down to an 80mm bore drops the both-way output to 2268 N at 0.5 MPa, while moving up to 125mm increases it to 5734 N. The twin rods keep the load guided against rotation better than a single rod.
This model uses the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits FB, CA, CB, and CR accessories. Note that a plain SAID does not hold its load when air is lost; the piston drifts. Use a SAIL or BSAID lock cylinder if position holding is required.
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 SAID100 Double Rod Cylinder SAID100X85S FAQ
Because the 25mm rod occupies both sides of the piston, the effective annulus area is identical in both directions. It delivers 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552 as a profile cylinder. However, the SAID mounting set is reduced to Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR accessories used on single-rod SAI cylinders.
