In addition to protecting the bearing from external contaminants, dust seals also help to retain lubricants within the bearing housing. This is important because lubricants help to reduce friction and heat generation within the bearing, which can lead to wear and eventual failure. By keeping the lubricant in place, dust seals help to ensure that the bearing operates smoothly and efficiently

In terms of application, metal cased oil seals are widely used in automotive transmissions, axles, and engines. They are also prevalent in industrial pumps, compressors, and other equipment where oil or other fluids must be contained without leakage They are also prevalent in industrial pumps, compressors, and other equipment where oil or other fluids must be contained without leakage

metal cased oil seals. The ability of these seals to maintain a reliable seal under varying speeds and pressures makes them indispensable in many mechanical systems.


1. Leak Prevention One of the primary functions of a hub oil seal is to prevent oil leaks. If the oil seal fails, the lubricant can escape, leading to insufficient lubrication of the bearings and other critical components. This can result in increased wear and tear, decreased performance, and eventually, catastrophic failure.
