Metalworking spindles traditionally use oil lubrication with set feed rates, return lines, and a reservoir for cooling the oil. These high duty cycle metal working spindles sometimes require the added cooling effect on the bearings that this oil circulation provides. Conversely, most woodworking spindles now use grease with a sealed bearings.

The so-called bearing type value (kf) assumes the actual design of the bearing to be lubricated. This factor can have values between 0.9 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.

The ball mills are rotary equipment used in mining plants in grinding, which uses steel balls to reduce the particle size of the ore as shown in Fig. 1. The rotating assembly of the mill is supported by two bearings, called trunnion bearings indicated in Fig. 2. The bearings are static components having bushings, on which the mill rotates.

The large alternating stresses placed on ball mill trunnions and heads are a great example.
The use of a long trunnion cannot be avoided if hydrodynamic plain bearings are to be used, since such mill bearings are usually designed with a width/diameter ratio of approximately 0.4. This is because the oil film thickness is heavily influenced by this ratio. If the bearings are too narrow, the side leakage flow will be high …
