Description:

1. Selection overview
Hub bearings are very important part in terms of vehicle safety. Selecting the type of bearing most suited
to the vehicle ensures safety and is very important for exhibiting the required performance. To select the
best bearing, one must consider and evaluate the bearings from a variety of angles. The procedure for
selecting hub bearings is provided in the form of a flowchart.

2. Life calculation
Life of hub bearings is calculated by inputting reaction force (radial load and axial load) on the wheel given
as set traveling conditions as load. Each bearing is a "unit bearing" consisting of two rows of bearings. Life
of the bearings is calculated separately for the each of the bearings. Bearing life is calculated for the outer
and inner bearings. The shorter of the calculated values is considered the calculated life of hub bearings.

3. Hub bearing materials1 Raceway and rolling element materialsInnovations in steel manufacturing technologies such asvacuum gas removal, out-of-furnace smelting and continuouscasting have notably reduced harmful non-metallic inclusion,thus realizing longer bearing life. CX selects quality materialsthat best suit each type of bearing.

4. Lubrication The objective of lubricating bearings is to form a film of oil onrolling or sliding surfaces to prevent the metals from makingdirect contact with each other. Lubrication has the followingeffects: (1) Reduces friction and wear. (2) Extends bearing life
