Definitions
- the track joint assembly may include a first link having a first bore.
- the track joint assembly may also include a second link having a second bore.
- the track joint assembly may include a pin positioned at least partially within the first bore.
- the track joint assembly may also include an inner bushing positioned coaxially around the pin, and at least partially within the second bore.
- the track joint assembly may include an outer bushing positioned coaxially around the inner bushing.
- the track joint assembly may also include a seal assembly positioned between the first link and the second link to form a hermetic seal between the first link and the second link.
- links 110a and 110b need not be offset links. Rather, in some embodiments, links 110a and 110b may be inner links and outer links. In such embodiments, both ends of each opposing pair of inner links would be sandwiched between ends of opposing outer links, as is known in the art.
