Low-friction, abrasion resistant replaceable bearing surface

1. A low-friction, abrasion resistant system of replaceable bearing surfaces, comprising:

a device with at least one recess with a wall, the at least one recess including a first hole in the wall, the first hole having a first diameter;

at least one bearing surface configured to be inserted into and removed from the at least one recess, the at least one bearing surface including a second hole with a second diameter that is less than the first diameter;

at least one cross-pin configured to be positioned within the first hole and the second hole; and,

at least one washer positioned within the recess and configured to provide a biasing force to urge the bearing surface upward.

2. The system of claim 1 , wherein a surface of the least one cross-pin is configured to at least one of a) not contact and b) just contact a bottom surface of the first hole of the device when a force is applied to the bearing surface.

3. The system of claim 1 , wherein the biasing force of the washer urges a surface of the at least one cross-pin into contact with a top surface of the first hole of the device when no force is applied to the bearing surface.

4. The system of claim 1 , wherein the bearing surface is comprised of one of a steel and a Polycrystalline Diamond Compact (PDC).

5. The system of claim 1 , wherein the washer is one of a conical spring and a Belleville washer.

6. The system of claim 1 , further comprising at least one guard positioned within the recess between the bearing surface and the device.

7. The system of claim 1 , wherein the bearing surface includes a domed outer surface.

8. The system of claim 7 , wherein the outer surface of the bearing surface extends beyond an external surface of the device.

9. The system of claim 1 , wherein the device is one of a drill bit, a reamer, a cam shaft, a bearing, or an axle.

10. The system of claim 1 , wherein the cross-pin is at least one of a spiral pin, a roll pin, and a spring pin.

11. A method of replacing a bearing surface in a device, comprising:

obtaining the device with at least one recess with a wall, the at least one recess including a first hole in the wall, the first hole having a first diameter;

removing the bearing surface from the recess;

inserting at least one washer within the recess, the at least one washer being configured to provide a biasing force;

obtaining a replacement bearing surface, the replacement bearing surface including a second hole with a second diameter that is less than the first diameter;

inserting the replacement bearing surface into the at least one recess; and,

inserting at least one cross-pin into the first hole and the second hole.

12. The method of claim 11 , wherein the washer is inserted such that the biasing force of the washer urges a surface of the at least one cross-pin into contact with a top surface of the first hole of the device.

13. The method of claim 11 , wherein the bearing surface is comprised of one of a steel and a Polycrystalline Diamond Compact (PDC).

14. The method of claim 11 , wherein the washer is one of a conical spring and a Belleville washer.

15. The method of claim 11 , further comprising at least one guard positioned within the recess between the bearing surface and the device.

16. The method of claim 11 , wherein the bearing surface includes a domed outer surface.

17. The method of claim 16 , wherein the outer surface of the bearing surface extends beyond an external surface of the device.

18. The method of claim 11 , wherein the device is one of a drill bit, a reamer, a cam shaft, a bearing, or an axle.

19. The method of claim 11 , wherein the cross-pin is at least one of a spiral pin, a roll pin, and a spring pin.
