Bearing Tips: wheel bearings Lubrication

Most of bearing lubrication in wheel bearings under heavy low-speed operating conditions of work, the use of general type of lubricating grease filling the bearing lubrication and can be subjected to extremely satisfied with the results achieved, grease is commonly used calcium-based grease, lithium grease, aluminum grease and high temperature grease, the user can choose the most suitable grease depending on the circumstances.

Sealed wheel bearings sealed bearings are already filled with grease to prevent outward leakage, but also to prevent outside dust, impurities and moisture intrusion inside the bearing and affect the normal work. Since wheel bearings are mostly in the low-speed operation under heavy load, so the seal type bearings with rubber ring seal and labyrinth seal two structures. The rubber ring seal itself has a simple structure. Small footprint, reliable sealing performance, etc. has been widely used, but its shortcomings are at high temperature rubber lip seal is easy to premature aging and loss, it is at a high temperature working conditions, working wheel bearings should labyrinth seal.
