LOAD ACTING ON BEARING

LOAD ACTING ON BEARING

The Bearing work under to types of loads Axial load and Redial loads . As the bearing we use to take the friction less motion in an assembly. The act on these two loads.


                                                       




P = XF_r + YF_a

where
P	=	equivalent dynamic bearing load [kN]
Fr	=	actual radial bearing load [kN]
Fa	=	actual axial bearing load [kN]

The two load simultaneously act on bearing, the bearing selection always consider the load on which bearing will work. But there is no ideal condition where bearing take only single type of bearing load.To consider the both load we calculate the dynamic load.

now look at one method for selecting a rotary  bearing given a load/life specification. The following table gives a qualitative overview of the characteristics of each rotary bearing type. We use this table to select the configuration of the bearing.

In salaction of the bearing  the load is important to consider the right type of bearing ,to know more about the types of bearing please see TYPES OF BEARING.
