To retain the lubricant in the housing and to keep foreign materials from entering a bearing, a seal is used. Seals are specifically designed for this purpose and help ensure proper bearing function.

Explanation:

To retain the lubricant in the housing and to keep foreign materials from entering a bearing, a seal is used. While a shield (also called a shroud) may also serve a protective function for bearings, it is not specifically designed to retain lubricant within the housing. The seal's primary purpose is to prevent lubrication from escaping and to block contaminants from entering the bearing assembly, which can ensure proper functioning and longevity of the bearing.

To retain the lubricant in the housing and to keep foreign materials from entering a bearing, a seal is used. A seal is a device that is used to prevent the escape or entry of fluids or particles. It creates a physical barrier between the bearing and its surroundings, ensuring that the lubricant remains inside and contaminants stay out.
