Cylindrical roller bearings with tapered bores are usually used to allow easier adjustment of internal clearance. When the radial internal clearance becomes negative, the cylindrical roller bearings are preloaded. Generally, cylindrical roller bearings for the front end (fixed end) of the spindle are preloaded during operating. Bearing for the rear end (free end) are adjusted to produce a slight clearance during operating. The amount of radial internal clearance after mounted is based on several factors such as rotating speed, load, bearing size, required rigidity, etc.

Bearing life is usually expressed as the number of hours an individual bearing will operate before material fatigue develops on either the raceways or the rolling element. The usual life rating for industrial applications is called “L10” life. The L10 life is the number of hours which that 90% of bearings will survive； or, conversely, 10% of bearings will have failed in the L10 number of service hours. One thing to be noticed that, roller bearing has different factor when it comes to bearing life calculation.
