A track roller (26) includes a roller shell (28), a roller shaft (76) extending through the roller shell (28), and a collar (60). The collar (60) includes a center body (62) interference-fitted upon the roller shaft (76), and a seal carrier (74). A clearance (96) extends radially between a center body outer surface (72) and a face seal assembly (84) held in axial compression between the seal carrier (74) and the roller shell (28). An oil void (100) is formed in the center body (62) and fluidly connected to the clearance (96) to provide an increased oil volume for lubrication and heat-dissipation.

    Un galet de chenille (26) comprend une coque de galet (28), un arbre de galet (76) s'étendant à travers la coque de galet (28), et un collier (60). Le collier (60) comprend un corps central (62) ajusté par interférence sur l'arbre de galet (76), et un support de joint d'étanchéité (74). Un espace libre (96) s'étend radialement entre une surface externe de corps central (72) et un ensemble joint d'étanchéité de face (84) maintenu en compression axiale entre le support de joint d'étanchéité (74) et la coque de galet (28). Un vide d'huile (100) est formé dans le corps central (62) et relié fluidiquement à l'espace libre (96) pour fournir un volume d'huile accru pour la lubrification et la dissipation de chaleur.
