Understand Vertical Motor Bearings - Efficient Plant

11/4/2018· The thrust bearing is usually at the top of the motor and may consist of one or more angular contact bearings, a spherical roller bearing, or a hydrodynamic plate bearing. The force and direction (upward, downward, or balanced) of the applied axial load dictate the type and nuer of thrust bearings needed to obtain optimum performance and service life.

28/9/2021· 1.) Turbine Bearing Checks:- All the turbine bearings are checked for following:- A.) Visual: No deep Grooves, aberrations.Excessive porosity and localized dents are allowed and are the reasons for rejection of the bearings. B.) Bridge Gap reading : It is the reference of the axis of the shaft with respect to the parting plane of the pedestal.

Operation and Maintenance of Vertical Motors - Pumps and …

17/12/2011· Angular contact ball bearings are the most common thrust bearings in vertical motors. A single bearing is used for normal thrust loads. Two bearings can be used in tandem for 175 percent of normal thrust (see Figure 2), and three bearings can be stacked for 250 percent of normal thrust. Stacks of up to five bearings have been reported.
