Bearing installation and removal basics

Installing a radial ball or roller bearing properly is critical to achieve the full service life of the component an electric motor's shaft rotates with the rotor Therefore the inner ring of the bearing will require a press fit and the outer ring will be a line-to-line or a clearance fit Bearings less than 50

What's normal: The role of temperature in bearing

The ball bearings used in most electric motors are pre-greased shielded ball bearings Normal motor bearing operating temperatures range from 140 to 160F As in all bearing applications this measurement should be taken at the bearing outer ring If the outer ring is inaccessible take the measurement at the housing and add 15 to 20F

Guidelines for motor installations

Bearings Ball roller or sleeve bearings may be chosen in accordance with the apparatus involved Antifriction bearings including ball and roller types reduce starting friction and take up less space on the shaft than the sleeve type Usually they're used for totally enclosed motors and where the motor is to be operated in various positions

Basic electric motor bearing types loads and applications

Cyndi Nyberg Former EASA Technical Support Specialist There are two main types of load that act on the bearings of a motor – radial and axial Radial – A radial load is defined as a load that is applied perpendicular to the shaft An example of a radial load would be an overhung load such as with a sheave Axial – An axial load also referred to as thrust is a load that acts parallel

Electric Motor Ball Bearings Types Options

Jun 29 2016Most electric motors in industrial facilities consist of rolling element bearings either ball bearings or roller bearings We will explore these different types of bearings and sealing methods in this article Ball Bearing Used in direct coupled applications These can handle axial as well as radial loads Roller Bearing

Difference Between Roller Bearing and Ball Bearing

May 01 2011Most mechanical devices make use of one or the other type of bearings for their spinning parts Though both roller and ball bearings serve the same basic purpose their differences lie in their design and load bearing capacities Ball bearings make use of hardened spherical balls that can handle both radial as well as thrust loads

Rolling Bearing Lubrication for Critical Running Conditions

A greased roller bearing in an electric motor is offered to demonstrate the possible grease service life In general the suspension of rotors with grease-lubricated roller bearings is a widely used and well-known application and is a good example for a bearing subjected to various influencing factors
