Track Roller Features:
1. Wheel body:
forged from 50Mn round steel with good hardenability. The heat treatment process of quenching and tempering and medium frequency surface quenching ensures its strength and wear resistance.
two pieces roller shell rim. Heat treated shells for body strength and longer wear life.
Heat treated for a deep uniform hardened depth that provides wear life equal to link wear life.
2.Roller shaft:
shaft and bearing designed to carry and turn with heavy track weight forged and heat treated for strength.
Bearing surfaces are hardened and polished to reduce friction and wear
Center flange absorbs side thrust from roller shell.
3.Cast Iron bushing:
Supports the bronze sleeve bearing.
Cast from iron to absorb loads without permanent deformation.
Large lubricant reservoir to reduce heat build up
4.Bronzed sleeve bearing:
Sleeve design provides a large surface area for better load distribution.
Inner diameter surface is polished to a smooth finish.
Soft bronze coating in the bearing absorbs any small foreign particles before they can damage the shaft and seals.
