An apparatus comprising:
- a bearing having a bearing surface with a groove, the bearing positioned adjacent to a shaft, the groove facing the shaft;
- and
- a negative thermal expansion (NTE) material positioned in the groove, the NTE material at least partially filling the groove.
An apparatus comprising:
- a bearing having a cavity positioned in a surface of the bearing, the surface at least partially surrounding a longitudinal axis of the apparatus;
- and
- a negative thermal expansion (NTE) material positioned in the cavity, the NTE material at least partially filling the cavity.
An apparatus comprising:
- at least one surface having a groove;
- and
- a negative thermal expansion (NTE) coating at least partially covering one or more walls of the groove, the NTE coating positioned closer to an inner portion of the groove than the at least one surface.
