Designed for slower wear
The rotating bushing design of the Cat® Abrasion undercarriage greatly reduces wear between the bushing and the sprocket. The sprocket segments and center tread idlers can thus be re-used through at least two undercarriage lives. The new center tread idlers are narrower and have a larger diameter. They don’t touch the links, only the bushing, which eliminates link rail scalloping. The idler has a longer life because it touches a rotating bushing.
The larger diameter of the new carrier rollers means a longer life, therefore better timed intervals that fit with other components’ maintenance.
There are additional features and benefits related to a better resistance to wear:
Lower operating costs:
-
Savings between 35% and 70% compared to the original Cat undercarriage
-
Less maintenance thus less downtime
-
Extended components' lifespan More reliable
Reduced maintenance:
-
Balanced components' lifespan, regardless of use
-
Elimination of bushing turns
-
Sprockets and idlers last longer than two sets of chains
-
Improved joint integrity due to the new factory-sealed cartridge
Smoother ride:
-
Less vibration
-
Center tread idlers provide better guiding to the link assembly
-
The Cat® Abrasion undercarriage can now be adapted to D3 to D6 track-type tractors
-
Cat® Abrasion is actually the undercarriage found on D6R machines and is optional for D3 to D6N machines
-
This innovative undercarriage is also available for 953 and 963 track-type loaders
-
Cat® Abrasion was subjected to a rigorous on-site verification, logging over 160,000 hours on more than 160 machines for different applications and types of ground cover
