About the Airtac SAID50 Double Rod Cylinder SAID50BX5
The AirTAC SAID50X5 is a double-acting, double-rod ISO 15552 profile cylinder featuring a highly compact 5mm stroke. Because a piston rod exits both end covers, the annulus area is identical on both sides. This means the cylinder generates an equal 825 N of force in both extend and retract directions at 0.5 MPa, ensuring perfectly balanced motion control.
This specific variant is configured with SUS304 stainless steel rods (code B) for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel integrates sensor grooves on both sides for CMSE reed or DMSE electronic switches. Note that a 5mm stroke is a non-standard, made-to-order length requiring confirmation from the datasheet for exact overall dimensions.

Where the Airtac SAID50 Double Rod Cylinder SAID50BX5 Is Used
Short-Stroke Clamping
Ideal for brief, high-frequency clamping tasks where the 825 N both-way force secures a workpiece without rotational drift.
Symmetric Transfer
Provides perfectly balanced push-pull dynamics for transferring delicate components across a short 5mm gap.
Rear-Cam Actuation
The protruding rear rod drives a secondary cam or limit flag, sequencing a second mechanism simultaneously.
Is the Airtac SAID50 Double Rod Cylinder SAID50BX5 the Right Cylinder?
Selecting this non-standard 5mm stroke is ideal for extremely short clamping or ejection duties where symmetrical force is critical. If your application requires higher force, stepping up to the 63mm bore yields 1402 N both ways at 0.5 MPa; conversely, dropping to a 40mm bore reduces the both-way output to 528 N. Unlike a single-rod SAI, this double-rod design provides inherent anti-rotation properties and allows mounting a cam or position flag on the rear rod extension.
Remember that a plain SAID cylinder does not hold its load when air pressure is lost or exhausted; the piston will drift. For position holding without live pressure, consider an external rod lock or a SAIL variant. This model is dimensionally interchangeable per ISO 15552 and 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 versions.
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 SAID50BX5 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions. It provides 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
Yes, it is dimensionally interchangeable with ISO 15552 cylinders. However, the SAID series uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not support the FB, CA, CB, or CR brackets used on single-rod SAI cylinders.
