1. Overview
The SMC CY3B-Z series is a magnetically coupled rodless cylinder. Instead of a piston rod, the piston inside the tube is coupled to an external slider through strong magnets. This design eliminates the need for a projecting rod, reduces air leakage, and saves installation space, especially in applications requiring long strokes.
2. Key Features
Magnetic coupling: no mechanical connection between piston and slider → no external air leakage.
Space-saving design: compact, suitable for long-stroke movement within a limited installation area.
Reduced weight: redesigned cylinder body and end caps (approx. 16% lighter for ø32, 100 mm stroke).
Improved lubrication: equipped with a lube retainer that maintains a lubricant film, extending service life.
Longer wear ring: enhances smooth sliding motion and durability.
Custom options available:
Axial port type
Heat-resistant version
Hard chrome-plated tube
Oil-free exterior
High-speed type, dust-resistant, or anti-magnetic environment options
