X and Y are factors required for the calculation of equivalent dynamic bearing load for single and double row deep groove ball bearing, dependent upon axial load (Fa) and radial load (Fr). Therefore, if P o < F r, P = P o = F r. P o = Axial load and is equal to P o = + Where, F r is the radial force and F a is the Axial Force.

The socalled bearing type value (kf) assumes the actual design of the bearing to be lubricated. This factor can have values between and 10 for kinematically simple ball bearings. For kinematically complex bearings (like axial cylindrical roller bearings with high sliding friction) the kf factor can reach values up to 90.

Fig. 1 shows that there are four basic components The shell, the heads, the ring gear and the trunnions. The heads are usually bolted to the shell. The trunnions are secured to the heads by bolts or made integrally with the head. The ring gear is usually bolted to one head section. The forces acting on the mill are both static and dynamic.

Roller Bearings Information. Roller bearings are used to replace sliding movement with low friction, rolling motion in rotary applications. The principal types of roller bearings are cylindrical, spherical, and tapered. In general, roller bearings offer higher load capacities than ball bearings of the same size.

Bearing internal clearance ( fig. 1) is defined as the total distance through which one bearing ring can be moved relative to the other in the radial direction (radial internal clearance) or in the axial direction (axial internal clearance). Initial internal clearance is the internal clearance in the bearing prior to mounting.
