About the Airtac SAID50 Double Rod Cylinder SAID50AX135S
The AirTAC SAID50X135-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and a 135mm non-standard made-to-order stroke. Because a rod exits both end covers, the annulus area is identical on both sides, yielding an equal extend and retract force of 825N at 0.5 MPa. This symmetric output is ideal for mechanisms requiring consistent push and pull dynamics.
This specific configuration includes an -S magnet for position sensing and a SUS420J2 stainless steel rod for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches precisely where needed. The through-rod design also permits mounting a cam or limit flag on the rear rod to trigger secondary mechanisms.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX135S Is Used
Symmetric Force Transfer
Drives transfer shuttles where the 825N push and pull forces must be perfectly matched to prevent motor stall or uneven acceleration across the stroke.
Twin-Station Actuation
Uses the front rod end to drive a primary workpiece while the rear rod end simultaneously operates a secondary valve or clamps a parallel fixture.
Anti-Rotation Slides
Leverages the dual-rod guidance to keep the load perfectly aligned and prevent torsional twisting during vertical lifting or pressing tasks.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX135S the Right Cylinder?
Choose this 50mm bore double-rod cylinder when your application demands equal bidirectional force and anti-rotation guidance that a single-rod SAI cannot provide. If you need less force, the 40mm bore offers 528N both ways at 0.5 MPa; stepping up to the 63mm bore yields 1402N. Remember that a plain SAID does not hold a load when air is exhausted—use a SAIL or BSAID for locking requirements. This model is dimensionally interchangeable per ISO 15552, requiring PT G1/4 ports and mounting accessories from the SAID set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAID50AX135S FAQ
Because the double-rod design occupies volume on both sides of the piston, the effective area is equal in both directions. It provides 825N of force both extending and retracting at 0.5 MPa, and 1154N at 0.7 MPa.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on single-rod variants.
