About the Airtac SAID50 Double Rod Cylinder SAID50X160
The AirTAC SAID50X160 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 160mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal extend and retract force of 825 N at 0.5 MPa. A rod protrudes from both end covers, allowing you to mount the primary workpiece on one end and a position flag or secondary cam on the rear.
This through-rod architecture provides superior anti-rotation guidance compared to a single-rod SAI. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a standard carbon steel rod and a PT tapered port thread, operating at speeds from 30 to 800 mm/s.

Where the Airtac SAID50 Double Rod Cylinder SAID50X160 Is Used
Symmetric Transfer
Drives a shuttle mechanism where the equal 825 N push and pull forces ensure consistent momentum transfer in both directions without needing pressure compensation.
Anti-Rotation Slide
The twin through-rods prevent the load from twisting during transit, providing precise linear guidance for a vertical lifting slide.
Rear-Cam Actuation
The front rod drives the primary workpiece while the rear rod end operates a secondary mechanical cam or limit flag for sequenced timing.
Is the Airtac SAID50 Double Rod Cylinder SAID50X160 the Right Cylinder?
Choose this 50mm bore when an application demands symmetric force and speed both ways, outputting 825 N at 0.5 MPa. If your mechanism requires less force, step down to the 40mm bore (528 N both ways); if you need more thrust, the 63mm bore offers 1402 N. The twin-rod design is specifically selected over a single-rod cylinder when dual-side guidance or rear-rod actuation is required. Note that the adjustable air cushions only decelerate the piston near stroke ends; this cylinder will drift and cannot hold a load if air pressure is lost. For secure holding without live pressure, consider an external rod lock or the SAIL series.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard double-rod profile cylinders. Specify the 50mm bore, 160mm stroke, PT port, and mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2) for your RFQ. Since the stroke is 160mm, side loads are moderate, but always ensure proper alignment to avoid rod-bearing bending.

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 SAID50X160 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 extend and retract directions at 0.5 MPa, and 1154 N at 0.7 MPa.
Yes, the SAID50X160 is dimensionally interchangeable per ISO 15552 profile standards. It uses a standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and can serve as a drop-in replacement for other ISO 15552 double-rod cylinders.
