3.Products advantage

1.Forgedsteel deep-hardened
2.High strength of roller body to avoid bell mounting effect
3.Lifetime lubrication for no maintenance requirements
4.Specially designed excavator rollers for high impactapplications
5. Dozer roller designed for high wear load
6.Special Boron-Manganese modified fine grain alloy to ensure   quality and consistency
7.Differential hardening process provides hardness in high wearareas and an elastic core to resist shock and impact loads
8.Uniform hardening to provide maximum wear life of track chainsand rollers and to all of the components that are in frictionalcontact, like (idlers, pins, bushings and sprockets)
