About the Airtac SAID63 Double Rod Cylinder SAID63X900S
The AirTAC SAID63X900-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and a 900mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding exactly 1402 N of output force at 0.5 MPa on both extend and retract. Equipped with a magnet (-S), it integrates seamlessly with AirTAC CMSE reed and DMSE solid-state sensors mounted in the dual-side barrel grooves.
The through-rod design allows one end to drive the primary workload while the opposing rear end mounts a secondary cam, position flag, or external guide. This carbon-steel rod configuration provides superior anti-rotation stability compared to a single-rod SAI. As a genuine ISO 15552 extruded-aluminum cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders without relying on proprietary tie-rod footprints.

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 SAID63 Double Rod Cylinder SAID63X900S Is Used
Symmetric Transfer
Equal 1402 N force in both directions makes this cylinder ideal for pushing and pulling parts across a machining cell without needing pressure adjustments.
Dual-Station Actuation
Mount the primary workpiece on the front rod and a secondary cam or tooling on the rear protruding rod to sequence two operations in perfect mechanical sync.
Anti-Rotation Slides
The twin carbon-steel rods prevent piston twist during long 900mm traverses, keeping guided loads perfectly aligned without external torsion.
Is the Airtac SAID63 Double Rod Cylinder SAID63X900S the Right Cylinder?
Selecting this 900mm stroke means operating beyond the 63mm bore standard maximum of 1500mm, classifying it as a non-standard made-to-order unit. When sizing force, remember the twin rods make push and pull forces equal at 1402 N (0.5 MPa); if your application needs less force, step down to the 50mm bore (825 N), or step up to the 80mm bore (2268 N) for heavier loads. The PT tapered porting matches the G3/8 interface. Mounting options are limited to the SAID subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
Because the stroke is 900mm, the long unsupported rod length increases the risk of rod-bearing bending under side loads; an external linear guide is highly recommended to prevent premature wear. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end and do not hold a load. If the mechanism must maintain position without live air pressure, use a SAIL pneumatic lock, a BSAID clamp-lock cylinder, or an external pilot-operated check valve.

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 SAID63 Double Rod Cylinder SAID63X900S FAQ
The double-rod design means the effective area is the same on both sides, so it provides 1402 N of force at 0.5 MPa in both the extend and retract directions. At 0.7 MPa, it provides 1962 N both ways.
Yes, the SAID63X900-S is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses the standard SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and features a G3/8 port.
