Undercarriage represents a significant investment for any tracked machine, that’s why we offer genuine Komatsu undercarriage for all Komatsu excavators and dozers. Komatsu also offers a range of alternative undercarriage products to suit non-Komatsu machines.
Our complete range of Undercarriage component options including: track groups, link assemblies, grouser plates, track rollers, carrier rollers, idlers, sprockets, pins and bushes. All of which can be tailor made to your machine, applications and ground conditions.
Komatsu undercarriage are designed for each machine to deliver long life and to optimize the performance of your Komatsu equipment. This adds up to real costs savings, with fewer work stoppages and reduced labour costs.
GST – GREASED SEALED TRACK
For all excavator models
The Komatsu GST undercarriages use high performance grease to lubricate pins and bushings, and reduce internal wear. Their steel is optimally hardened during manufacturing, to ensure a longer lifetime and maximum reliability.
SALT – SEALED & LUBRICATED TRACKS
Komatsu SALT undercarriages feature lubricating oil between pins and bushings, as well as unique high-performance seals that minimize the risk of link pitch extension and maximize wear life. You can choose from a wide variety of SALT undercarriages tailored to fit different applications.
PLUS – PARALLEL LINK UNDERCARRIAGE SYSTEM
D37, D51, D61, D65
The PLUS undercarriage is ideal for any application – no matter the level of impact and abrasion. Its main feature is a unique rotating bushing that minimizes wear between itself and the sprocket and therefore has a longer track life. All other PLUS components are different from those on a standard undercarriage, and were redesigned to last up to twice as long.
AR – ABRASION RESISTANT TRACK
D41, D51, D61, D65
The bushings of the Abrasion Resistant track (AR) are thoroughly heat treated giving the track a 50% longer life compared to standard tracks. The track is available with heavy duty or standard links, depending on the machine.
HD-AIR TRACK – HD ABRASION IMPACT RESISTANT TRACK
It features AIR bushings that are more impact resistant than on the standard track and more flexible than on the AR track, making the track suitable for both abrasive and impact applications. It is also equipped with Heavy Duty links that are bigger and more durable than standard ones.
DUAL BUSHING TRACK
D275, D375, D475
The Dual Bushing Track is a unique system with two bushings, an inner fixed bushing with an outer bushing that rotates around it which lengthens the life of the track by 100% compared to standard tracks.
