1. An undercarriage track roller, comprising: a shaft;at least one collar operatively associated with the shaft, the collar having a top portion and a bottom portion;a guard plate operatively associated with the collar;at least one rim rotatably associated with the shaft and interfacing with the collar;a labyrinth formed between the collar and the rim, the labyrinth being at least partially overshadowed by the guard plate; anda variably angled face disposed on the collar, the variably angled face interfacing with the rim and forming the labyrinth between the collar and the rim, wherein the variably angled face of the collar is closer to the rim along the top portion of the collar and further from the rim along the bottom portion of the collar such that the labyrinth is larger along the bottom portion of the collar than the top portion of the collar to allow particles of debris to escape through the labyrinth. 2. The undercarriage track roller of claim 1, wherein the guard plate includes a solid upper portion along the top portion of the collar and includes at least one recess along a lower portion of the guard plate on an inner face of the guard plate interfacing with the rim. 3. The undercarriage track roller of claim 1, wherein the guard plate includes a solid upper portion along the top portion of the collar and has at least one gap along a lower portion of the guard plate. 4. The undercarriage track roller of claim 1, wherein the guard plate is integral with the collar. 5. A machine, comprising: a chassis;at least one continuous track supporting the chassis;an undercarriage including at least one undercarriage track roller configured to support and guide the at least one continuous track, the at least one undercarriage track roller including; a shaft;at least one collar operatively associated with the shaft, the collar having a top portion and a bottom portion;a guard plate operatively associated with the collar;at least one rim rotatably associated with the shaft and interfacing with the collar;a labyrinth formed between the collar and the rim, the labyrinth being at least partially overshadowed by the guard plate; anda variably angled face disposed on the collar, the variably angled face interfacing with the rim and forming the labyrinth between the collar and the rim, wherein the variably angled face of the collar is closer to the rim along the top portion of the collar and further from the rim along the bottom portion of the collar such that the labyrinth is larger along the bottom portion of the collar than the top portion of the collar to allow particles of debris to escape through the labyrinth. 6. The machine of claim 5, wherein the guard plate is integral with the collar. 7. The machine of claim 5, wherein the guard plate is annular. 8. The machine of claim 5, wherein the guard plate has at least one void. 9. The machine of claim 8, wherein the void is a recess along an inner face of the guard plate and the inner face interfaces with the rim. 10. The machine of claim 9, wherein the recess is disposed on a lower portion of the guard plate. 11. The machine of claim 8, wherein the void is a gap. 12. The machine of claim 11, wherein the gap is disposed on a lower portion of the guard plate. 13. The machine of claim 5, wherein the guard plate has at least one recess and at least one gap. 14. An undercarriage track roller, comprising: a shaft;at least one collar operatively associated with the shaft, the collar having a top portion and a bottom portion;at least one rim rotatably associated with the shaft and interfacing with the collar;an annular guard plate operatively associated with the collar, the guard plate including an inner face which interfaces with the rim;a labyrinth formed between the collar and the rim, the labyrinth being at least partially overshadowed by the guard plate;a variably angled face disposed on the collar, the variably angled face interfacing with the rim and forming the labyrinth between the collar and the rim, wherein the variably angled face of the collar is closer to the rim along the top portion of the collar and further from the rim along the bottom portion of the collar such that the labyrinth is larger along the bottom portion of the collar than the top portion of the collar to allow particles of debris to escape through the labyrinth; andwherein the guard plate includes a solid upper portion along the top portion of the collar and wherein a lower portion of the guard plate includes one or more voids, the one or more voids configured to allow particles of debris to escape the undercarriage track roller after falling through the labyrinth. 15. The undercarriage track roller of claim 14, wherein the one or more voids include one or more of at least one recess bounded within the inner face of the guard plate interfacing with the rim and at least one gap formed through the guard plate. 16. The undercarriage track roller of claim 14, wherein the one or more voids are along an outer perimeter of the guard plate. 17. The undercarriage track roller of claim 16, wherein the one or more voids include at least one gap formed through the guard plate.
