About the Airtac SAID80 Double Rod Cylinder SAID80X85S
The AirTAC SAID80X85-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a piston magnet for position sensing. Because a rod extends from both end covers, the effective piston area is identical in both directions, yielding an equal extend and retract force of 2268 N at 0.5 MPa. This through-rod geometry provides superior anti-rotation stability for guided loads compared to a single-rod SAI.
This 80mm bore variant features a 25mm carbon steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches wherever fits best. You can attach a workpiece to the front rod end and a cam or position flag to the rear, driving two mechanisms in perfect synchronization.

Where the Airtac SAID80 Double Rod Cylinder SAID80X85S Is Used
Symmetric Force Transfer
Drives a transfer carriage where the push and pull strokes must move identical masses at the exact same speed, leveraging the 2268 N equal both-way thrust.
Anti-Rotation Slides
Guides a heavy machining fixture using both rod ends to prevent rotational drift under high lateral loads, ensuring precise tool alignment.
Through-Rod Sensing
Actuates a clamping mechanism on the front stroke while the rear rod end trips a DMSE electronic sensor to confirm full extension to the control system.
Is the Airtac SAID80 Double Rod Cylinder SAID80X85S the Right Cylinder?
Select this 80mm bore when an application demands symmetric thrust of 2268 N both ways at 0.5 MPa, stepping up from the 63mm bore (1402 N) for heavier loads, or down from the 100mm bore (3681 N) if you need to save space. The double-rod design is chosen over a single-rod cylinder when the mechanism requires dual-side guidance to prevent rotation, or when a rear rod end is needed to trip a limit switch. To match this cylinder for an ISO 15552 drop-in replacement, specify the 80mm bore, 85mm stroke, PT G3/8 port, and the -S magnet option.
Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. If air pressure is lost, the cylinder will drift, so an external pilot-operated check valve or a BSAID clamp-lock cylinder is required for position holding. The 85mm stroke is short enough to avoid rod-bearing bending, but always ensure the rear rod has adequate clearance to protrude safely.
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 SAID80 Double Rod Cylinder SAID80X85S FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. It delivers 2268 N both ways at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, the SAID80X85-S is dimensionally interchangeable per ISO 15552. It uses the standard mounting interface and accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, but omits FB, CA, CB, and CR mounts.
