The concept of embeddability of a bearing primarily refers to the ability of the bearing material to allow small particles to embed within it, which enhances the protective properties of the bearing surface. This property can play a significant role in the performance and longevity of bearings, as it aids in the prevention of wear by creating a sort of buffer against friction and abrasive particles.

When particles embed themselves into the softer material of the bearing, they can help to reduce surface contact between the moving parts, thereby minimizing damage and wear. This is an important characteristic, especially in conditions where contaminants are present, as it can lead to a more effective sealing and less direct contact between the bearing and shaft surfaces.

In contrast, the other answer choices do not accurately describe embeddability. Thickness relates to the physical dimensions of the bearing but does not involve its interaction with other materials. The idea of molding to the crankshaft shape pertains more to fit and installation rather than the performance attribute of embeddability. The capacity to withstand heat is related to the bearing's thermal characteristics, which does not directly correlate with its ability to embed particles. Understanding embeddability is crucial for selecting and maintaining bearings in automotive applications to ensure optimal performance and durability.
