End play cold thrust bearing clearance is defined as what?

End play cold thrust bearing clearance refers to the distance the thrust collar can be moved without load. This clearance is critical because it ensures that the thrust bearing operates effectively within its design parameters, allowing for thermal expansion and other operational factors without resulting in mechanical failure.

In a thrust bearing, the thrust collar's movement must be adequately defined to prevent excessive wear or damage during operation. This clearance allows for some axial movement while ensuring that the thrust bearing maintains its functional integrity when loads are applied.

Other options do not accurately describe the concept of cold thrust bearing clearance. For instance, the distance the rotor can rotate pertains to rotational motion rather than axial movement. Similarly, load capacity refers to the bearing's strength and ability to withstand forces rather than the movement of its components. Lastly, the axial distance between rotor and stator does not specifically address the concept of clearance or movement of the thrust collar without load.
