ABOUT QUALITY

1. Roller Body: Material is 40Mn2 ---hard wearing,  so, that can extend the roller's service life.

3. Pin: The material is 42Cr

4. Floating seals: the size of Floating seals must 100% match the roller. If not, the oil will spilling.

5. The most important process is Hardening and Tempering if the rollers are not undereardening and tempering, the Mechanical  Properties, Yield Strength and Tensile Strength will not be good, the roller will be slip easily.
