About the Airtac SAID80 Double Rod Cylinder SAID80BX850
The AirTAC SAID80X850 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 850 mm stroke. Because a piston rod exits both end covers, the annular area is identical on both sides. This yields equal push and pull forces, delivering 2268 N in each direction at 0.5 MPa and 4082 N at 0.9 MPa. The G3/8 PT porting and 36 mm adjustable air cushions manage pneumatic flow efficiently.
This specific unit is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the 850 mm stroke exceeds the standard 1500 mm maximum for this bore, classifying it as a non-standard made-to-order configuration. You must also account for the extra physical clearance required at the rear where the secondary rod protrudes during operation.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX850 Is Used
Symmetric Force Transfer
Drives a heavy transfer carriage with identical 2268 N push and pull forces at 0.5 MPa, ensuring consistent momentum in both directions without speed variation.
Anti-Rotation Slides
Uses the twin-rod structure to guide a vertical welding slide, preventing torsional twist and maintaining precise alignment over the 850 mm travel.
Dual-Station Actuation
Mounts a clamping fixture on the front rod and a mechanical limit flag on the rear rod to sequence two operations simultaneously from one cylinder.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX850 the Right Cylinder?
Choose this 80 mm bore when an application requires symmetric force and dual-side actuation that a single-rod SAI cannot provide. Stepping down to a 63 mm bore yields 1402 N at 0.5 MPa, while stepping up to a 100 mm bore provides 3681 N. This SAID80X850 is ideal for driving a primary workpiece on one end and a position flag or cam on the rear rod.
Since the 850 mm stroke is non-standard and exceeds typical lengths, the 25 mm rod faces increased bending risks over the extended travel. Always use an external guide to prevent side-load damage to the rod bearings. This cylinder is dimensionally interchangeable per ISO 15552, but plain SAID cylinders do not hold loads without live pressure; if position holding is needed, consider a SAIL or BSAID variant. Mounting options are restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAID80BX850 FAQ
The SAID80X850 provides equal force in both extend and retract directions due to its double-rod design. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 mounting interfaces. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR accessories found on single-rod variants.
