1. TRACK LINKS

Continuous research in steel metallurgy together with computerized management of all working parameters ensure GETT links attain the finest possible quality standards and place them among the best products available for this particular market. 
GETT links excellent wear resistance, even in the most severe working conditions, is assured by modern rail induction hardening systems as well as accurate control systems, complying with ISO9001 International Standards. 
GETT links have a running rail surface hardness of Rockwell C 55, a case depth hardness of Rockwell C 45 (from 5 to 13 mm depending on size) and a core hardness of Rockwell C 30.

2. PIN&BUSHING

Yuchang has given priority to the significant requirement of reducing pin and bushing friction wear in their chains.
These components, track bushings in particular, are of fundamental importance to chain durability and are therefore manufactured by Yuchang on the basis of a specific integral process using the most modern design and production systems.
Track bushings have a surface hardness of Rockwell C 60, a case depth hardness of Rockwell C 50 (from 1.5 to 3.5 mm depending on size), tempered ends (depending on chain type) and a core hardness of Rockwell C 40.
Track pins have a surface hardness of Rockwell C 60 and a case depth hardness of Rockwell C 50 (from 2.5 to 7 mm depending of size).

3. ASSEMBLY

Assembly is another area of vital importance for strong performance in the field.
Yuchang, drawing on its technological and product experience and expertise, has designed and built fully automatic chains assembly lines and,inthe case of lubricated chains, automatic oil seal control and filling devices for the pin cavities.
