SMC Magnetically Coupled Rodless Pneumatic Cylinder CY3B6-50

SMC Magnetically Coupled Rodless Pneumatic Cylinder CY3B6-50 Precision High-Strength Piston Rod

Attribute	Value
Stroke	50mm
Bore	6mm
Manufacturer Series	CY3B
Action	Double
Maximum Operating Pressure	7 bar

Improved lubrication

A Lube-retainer is installed to support lubrication retention on the piston and to ensure a lubrication film. (Bore size: ø15 to ø63)

Stable operation

Lengthening of the wear ring on the body side by, 30% at maximum, helps to achieve smooth movement.

MThe specifications, magnet holding force, and mounting dimensions are the same as those of the existing CY3B series model.

Max. Weight of Connection Bracket to the Body

The CY3B series is guided by an external axis (such as a linear guide) without directly mounting the load. When designing a metal bracket to connect the load, make sure that its weight will not exceed the value in the table on the right. (For connection methods, refer to the Operation Manual.)

• Max. Connection Bracket Weight

Vertical Operation

It is recommended that the load is guided by a ball type bearing (linear guide, etc.). If a slide bearing is used, sliding resistance increases due to the load mass and moment, which may cause malfunctions. When the cylinder is mounted vertically or on an angle, be sure to use an external stopper, etc., for positioning. In addition, as the slider may move downward toward the stroke end due to its self-weight or the mass of the workpiece, use an external stopper, etc., for positioning if accurate positioning is required.

Bore size [mm]	Model	Allowable load mass (Wv) [kg]	Max. operating pressure (Pv) [MPa]
