Forged from deep hardening steel and heart treated for internal strength to
resist bell mounting and to increase rebuild ability.
2 pieces roller shell
rim. Heat treated shells for body strength and longer wear life.
Heat treated
for a deep uniform hardened depth that providers wear life equal to link wear
life.
Thru-hardened flanges to resist bending and improve rebuild
ability
Roller Shafts
Shafts 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.
Cast Iron Bushing
Supports the bronze sleeve
bearing.
Cast from iron to absorb loads without permanent
deformation.
Large lubricant reservoir reduce heat build up.
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.
Functions:
Support the track as its most
between the sprocket and idler.
Guide the track between the sprocket and
idler.
Strength to resist failure before tread wear life is
utilized.
Treads wear life matched to track links.
Treads and flanges
rebuild able on forged shells.
