| Producing Method | Specification | Material |
|---|---|---|
| Casting Steel | It has suitable ductility for general structural use and also has excellent strength. | SC460 |
| It can be manufactured using various materials according to customer requirements. | SC490 | |
| Casting Iron | Because of its high carbon content, it has low ductility and strength. | CI, FC, FCD |
| However, it has excellent wear resistance because it can absorb vibrations and has its own lubricating ability. | ||
| Welding | Welded sheaves are manufactured by dividing them into Rim Disk and Boss and welding them together. | S35C |
| Rim disk made by S35C or S45C, and the groove part is hot-formed to provide excellent lubricity and wear resistance. | S45C | |
| Forged | It is manufactured by machining forged materials. | S45C |
