Track Roller Main Features:
1.Forged from deep hardening steel and heart treated for internal strength to resist bell mounting and to increase rebuilding ability.
  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.



Excavator and Dozer Lower Roller Functions:
1.Support the track as its most between the sprocket and idler.
2.Guide the track between the sprocket and idler
3.Strength to resist failure before tread wear life is utilized.
4.Treads wear life matched to track links.
5.Treads and flanges rebuild able on forged shells.
6.Thru-hardened flanges to resist bending and improve rebuild ability.
