Cable Beads

Introduction:

Cable bead adopts structure of cable with a core ringing the center; The outer layer is composed of multiple　strands of wire winded on the ring core, and the cross section of bead is circular. The outer layer can be one　or more, between the layers the direction of winding　can be either the same or different.

Compared with the traditional structure of bead(such　as hexagon), cable bead has no sharp corners. As a　result, It is not easy to form stress concentration or　have a cutting effect on the carcass cord, which leads　to a better performance in protecting the tire.

Advantage of cable Beads:

Tire performance:
1. The light weight -- helps to lower the rolling resistance of the tire.
2. High strength -- the cable bead is about 20% lighter for the same tensile strength.
3. Tire bead area strength is high – Less deformation after vulcanization.
4. The uneven stress of hexagonal bead is solved.
5. The stress of the bead in tire: the hexagonal bead has a larger deformation ratio and stress value than cable bead.

Main application of cable Beads:
1. Aircraft tires &Aero tires
2. Racing tires
3. EV tires

4. Air spring system
