About the Airtac SAID50 Double Rod Cylinder SAID50BX195
The AirTAC SAID50X195 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 195 mm stroke. Because a SUS304 stainless steel rod exits both end covers, the annulus area is identical on both sides. This yields equal push and pull forces, delivering 825 N each way at 0.5 MPa and 1154 N at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This through-rod design provides superior anti-rotation guidance compared to a single-rod SAI cylinder. You can mount the primary workpiece on one end and attach a position flag, cam, or secondary mechanism to the rear rod. The PT tapered port threads and adjustable air cushions at both ends ensure reliable, shock-free operation in demanding pneumatic setups.

Where the Airtac SAID50 Double Rod Cylinder SAID50BX195 Is Used
Symmetric Force Transfer
Drives loads that require identical push and pull dynamics, using the through-rod design to ensure equal 825 N force and speed in both directions.
Anti-Rotation Slides
Utilizes the twin SUS304 rods to guide loads and prevent rotation, ideal for precision machining slides where a single rod would allow unwanted deflection.
Dual-Mechanism Actuation
Mounts the primary tool on the front rod end and a secondary cam or position flag on the rear rod end to trigger external sensors or secondary mechanisms.
Is the Airtac SAID50 Double Rod Cylinder SAID50BX195 the Right Cylinder?
Choose this 50 mm bore when an application requires symmetric force and speed in both directions, offering 825 N at 0.5 MPa. If you need less force, step down to the 40 mm bore (528 N); if you need more, step up to the 63 mm bore (1402 N). Unlike a single-rod SAI, this double-rod configuration is selected when dual-side guidance, anti-rotation control, or rear-rod sensing is required. It uses the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod variants.
Since this is a 195 mm stroke, it falls under standard lengths and does not require external side-load guides, though long unsupported strokes always benefit from proper mounting. Remember that a plain SAID does not hold its load when air is exhausted or the valve is centered; the piston will drift. For position holding without live pressure, consider the SAIL (air-released lock) or BSAID (clamp-lock) series. This model is dimensionally interchangeable per ISO 15552, making it a drop-in replacement for other ISO 15552 double-rod cylinders.

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 SAID50BX195 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides, resulting in equal force for both extend and retract strokes. It provides 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa in both directions.
Yes, the SAID50X195 is dimensionally interchangeable per ISO 15552 and can serve as a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a G1/4 port and supports the standard SAID mounting accessories (Basic, FA, LB, TC, FTC, TCM1, TCM2).
