Radial and Axial Load Rating Information for S Bearings

Heavy duty bearing types such as 6200 or 6300 series may take axial loads of up to 50 percent of the static radial load rating. Thin-section deep groove ball bearings can only support axial loads of between 10 and 30 percent of the bearing''s static radial load rating due the shallower raceways. Please note, these figures are based on pure axial

Understand Vertical Motor Bearings - Efficient Plant

11/4/2018· Angular-contact ball bearings are the most common types of thrust bearings. A single bearing is used for normal thrust loads; two bearings in tandem (Fig. 3) for 175% of normal thrust (placing two bearings in tandem does not double the thrust capacity); and a stack of three bearings for 250% of normal thrust (see table above).
