About the Airtac SAID50 Double Rod Cylinder SAID50X150S
The AirTAC SAID50X150-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 150mm stroke. Because a carbon steel rod exits both ends, the effective piston area is identical on extend and retract, yielding a perfectly balanced 825N of force in either direction at 0.5 MPa. The included -S magnet enables position tracking via AirTAC CMSE reed or DMSE solid-state sensors.
This through-rod architecture allows you to mount the primary workpiece on one end and a secondary cam, limit flag, or guidance mechanism on the opposite rear end. The extruded aluminum barrel integrates sensor grooves on both sides, while adjustable air cushions at both ends ensure smooth deceleration across the 30-800 mm/s speed range.

Where the Airtac SAID50 Double Rod Cylinder SAID50X150S Is Used
Symmetric Transfer
Provides equal 825N force in both directions, making it ideal for pushing and pulling loads identically in automated transfer lines.
Anti-Rotation Slides
The twin-rod design prevents mechanical twisting under offset loads, keeping precision sliding fixtures perfectly aligned.
Through-Rod Sensing
Mount the primary tool on the front rod and a DMSE sensor target flag on the rear protruding rod for dual-station verification.
Is the Airtac SAID50 Double Rod Cylinder SAID50X150S the Right Cylinder?
Choose this 50mm bore when an application demands equal push/pull forces and anti-rotation guidance that a single-rod SAI cannot provide. If your project requires less force, stepping down to the 40mm bore yields 528N both ways, while moving up to the 63mm bore provides 1402N. The SAID50X150-S is dimensionally interchangeable per ISO 15552, using a PT G1/4 port and supporting Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts (omitting FB, CA, CB, and CR).
Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If your system loses air pressure or the valve is centered, the cylinder will drift, requiring an external pilot-operated check valve or a SAIL/BSAID lock cylinder for position holding.
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 SAID50X150S FAQ
Because the double-rod design occupies both sides of the piston, the effective annulus area is equal in both directions. It generates 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa on both extend and retract strokes.
Yes, the SAID50X150-S is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses a PT G1/4 port and supports standard mounts like FA, LB, and TC, though it omits FB, CA, CB, and CR accessories.
