yellow colour picture is sprocket by forging

1. Cast steel for optimum internal grain flow

2. Single shot Induction hardening for high surface hardness(HRC>50)

3. Effective hardened depth 4-10mm for HRC45

4. Tempered to resist cracking and chipping including harding and tempering one the whole sprocket

5. Optimized design to reduce stress concentration areas

6. Hunting tooth design extends wear life

7. Accurate machinine of the mounting surfaces ensure best performance
