Link Assembly


Komatsu Link Assemblies

Komatsu offers both bulldozer and excavator link assemblies. Bulldozer link assemblies are lubricated for longer life and the excavator link assemblies are sealed & greased.

For bulldozers Komatsu designed three types to address various working environments.

  • Standard undercarriage is available on all models. 
  • For small and medium size dozers Komatsu offers PLUS (Parallel Link Undercarriage System) assemblies which can deliver up to twice the life versus standard. This is an exclusive Komatsu design that features a rotating bushing to minimize wear between segment and bushing.
  • For large size bulldozer Komatsu offers Dual Bushing for
    use in highly abrasive applications. This design also offers a
    rotating bushing to minimize segment and bushing wear.
