Ordinary belt with a core
     Common with the core belt with wire rope core is mostly core, using a small part of the carcass band core. Since these two fibers with a core structure are twisted or prepared in belt clip each operation between the fibers with a core cause gradual elongation. Therefore, the use of wire rope core and fabric belt with a common core production can only be applied at low load transmission systems.

Special belt with a core
     Special belt with a core of polyester polymer with steel core using brown silk overall solid core rod with a core structure. Because brown silk polyester steel solid core untwisted structure as a whole, good adhesion, resistance, flex, high strength, do not run long, not only greatly improve the life of the rubber belts and belt body life balance, companies can do maintenance, periodic replacement. November 22, 2010, brown silk polyester steel skeleton material through the Committee of Experts identification: brown silk with polyester steel skeleton belt material as with conventional polyester soft rope, hard rope, aramid fiber rope skeleton structure belt material life than 5-10 times increase, is a leading international level. Special belt with a core effective solution to the high load heavy horsepower belt drive system change frequently common problems, much favored heavy industry around the world.
