Yes, NAF deep groove ball bearings made of materials such as stainless steel or ceramic can be used in high-temperature applications. However, it is important to ensure that the bearing lubrication is also suitable for high temperatures to prevent damage or failure. The maximum temperature that a ball bearing can withstand will depend on the specific materials and design of the bearing. It is recommended to consult with a bearing manufacturer or engineer to ensure the appropriate bearing is selected for the specific application.
