About the Airtac SAID50 Double Rod Cylinder SAID50BX65
The AirTAC SAID50X65 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and a 65mm non-standard stroke. Because the piston rod extends from both end covers, the effective annulus area is identical on extend and retract. This means you get equal push and pull force, delivering exactly 825 N of thrust in both directions at 0.5 MPa. The SUS304 stainless steel rods are highly corrosion resistant and provide excellent dual-side guidance to prevent load rotation.
The through-rod design allows you to mount the primary workpiece on one end and a position flag, cam, or secondary drive on the opposite rear rod end. It features adjustable air cushions at both ends and extruded aluminum barrel with dual-side sensor grooves. Note that because the rear rod protrudes continuously, you must allow extra clearance behind the rear cover for the stroke length.

Where the Airtac SAID50 Double Rod Cylinder SAID50BX65 Is Used
Symmetric Force Transfer
Ideal for pressing or transferring parts where the extend and retract forces must match exactly, utilizing the 825 N both-way output to push and pull with identical energy.
Anti-Rotation Slides
The twin SUS304 rods provide superior torsional rigidity and guidance, preventing the attached tooling plate from twisting during heavy side-loaded positioning tasks.
Through-Rod Sensing
Mount the primary workpiece on the front rod and attach a cam or position flag to the rear protruding rod end to actuate external mechanical limit switches.
Is the Airtac SAID50 Double Rod Cylinder SAID50BX65 the Right Cylinder?
Choose this 50mm bore double-rod cylinder when your mechanism requires perfectly symmetric force and speed in both travel directions, or when you need anti-rotation guidance and rear-rod sensing that a single-rod SAI cannot provide. If your application needs less force, the 40mm bore variant offers 528 N both ways at 0.5 MPa; if you need more power, stepping up to the 63mm bore yields 1402 N. This non-standard 65mm stroke is made-to-order, so confirm lead times.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders for drop-in replacements. It uses a PT tapered G1/4 port and supports the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR accessories. Remember that a plain SAID does not hold its load when air pressure is lost or exhausted; the cushions only decelerate the piston near stroke end. For position holding without live pressure, consider a SAIL or BSAID variant.
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 SAID50BX65 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers an equal force of 825 N in both the extend and retract directions at 0.5 MPa (1154 N at 0.7 MPa).
Yes, it shares the ISO 15552 mounting interface, but the double-rod design uses a reduced accessory set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not support the FB, CA, CB, or CR mounts found on single-rod cylinders.
