Magnetically Coupled Rodless Cylinder CY3R: High-Precision Manufacturing Solutions for Global Markets

Description

Series CY3R: Direct Mount Magnetically Coupled Rodless Cylinder

High-Precision, Space-Saving Linear Actuation

The Series CY3R is a direct-mount, magnetically coupled rodless cylinder designed for modern automation where space efficiency and mounting rigidity are paramount. This upgraded version features significant enhancements in durability and performance, including a 70% longer wear ring for improved bearing life and an integrated resin lubretainer on the dust seal to ensure consistent lubrication of the cylinder tube.

Performance & Holding Force

The magnetic coupling determines the cylinder’s holding capacity. Exceeding these limits can result in the decoupling of the internal and external sliders.

Engineering & Safety Precautions

1. Alignment: Long-stroke applications increase shaft deflection. For strokes where deflection is a concern, use a floating mechanism (e.g., XC57) to assimilate center axis variations.
2. Vertical Operation: Do not exceed the allowable vertical mass (e.g., 18.5 kg for ø25) to prevent accidental load drops.
3. Intermediate Stops: If using an external stopper, ensure operating pressure stays within safety limits (e.g., 0.65 MPa for ø15–63) to avoid magnetic decoupling.
4. Auto Switch Integration: Small auto switches (D-M9, D-A9) can be mounted flush in the integrated grooves for all sizes ø6 to ø63.
5. Magnetic Safety: The magnets have extremely strong attractive force. Handle with extreme caution during any disassembly or maintenance
