Unit Catalog. • After a product is removed from its packaging, it should be placed into service as soon as possible. • When removing a product that is not individually packaged from a bulk pack container, the container should be resealed immediately after the product is removed. • The storage area temperature should be maintained between 0° C and 40° C ( 32° F and 104° F); temperature fluctuations should be minimized. • The relative humidity should be maintained below 60 percent and the surfaces should be dry. • The storage area should be kept free from airborne contaminants such as, but not limited to, dust, dirt, harmful vapors, etc. • The storage area should be isolated from undue vibration. • Extreme conditions of any kind should be avoided. Due to the fact that Timken is not familiar with your particular storage conditions, we strongly suggest following these guidelines. However, you may be required by circumstances or applicable government requirements to adhere to stricter storage requirements. When you receive a bearing shipment, do not remove products from their packaging until they are ready for mounting so they do not become corroded or contaminated. Store bearings and bearing housings in an appropriate atmosphere so they remain protected for the intended period.

Following are some of the basic principles that are used. The loads on bearings are either radial or thrust. The sketch at the top of Figure 1 shows that radial loads act perpendicular to the bearing axis of rotation and thrust loads act parallel to the axis of rotation.

  • Long Term Storage Procedure - Large AC Motors Storage Storage Requirements for Motors That Will Not Be Placed in Service for at Least Six Months from Date of Shipment
    Long Term Storage Procedure - Large AC Motors Storage Storage requirements for motors that will not be placed in service for at least six months from date of shipment. Improper motor storage will result in seriously reduced reliability and failure. An electric motor that does not experience regular usage while being exposed to normally humid atmospheric conditions is likely to develop rust in the bearings or rust particles from surrounding surfaces may contaminate the bearings. The electrical insulation may absorb excess moisture leading to motor winding failure. Preparation for Storage If the motor is to be stored for any period of time prior to installation, it should be placed in an area that is clean, dry and warm. 1. Motors are to be kept in their original containers or provided with equivalent protection and stored in a location that is free from extremes in temperature, humidity and corrosive environments. If the storage location is cold, damp or severe humidity changes exist, the space heaters must be energized. 2. Motor must be stored in an environment with low vibration levels (less than 2 mils). If unusual vibration levels exist at the storage location, the motor should be protected with isolation pads Note: High environmental vibration can result in bearing damage or failure. 3. All breathers and drains are to be operable while in storage and/or the moisture drain plugs removed. Motors must be stored so the drain is at the lowest point. 4. Lubrication Requirements a. Motors with grease lubricated anti-friction bearings are shipped with the correct amount of grease in the bearings and do not require lubrication during storage periods up to 12 months.

  • LECTURE NOTES on MACHINE DESIGN II III B.Tech II Semester
    LECTURE NOTES ON MACHINE DESIGN II III B.Tech II Semester UNIT 1 JOURNAL BEARINGS 1.1 WHY TO STUDY FRICTION, WEAR & LUBRICATION? Moving parts of every machine is subjected to friction and wear. Friction consumes and wastes energy. Wear causes changes in dimensions and eventual breakdown of the machine element and the entire machine. The loss of just a few milligrams of material in the right place, due to wear can cause a production machine or an automobile to be ready for replacement. If we imagine the amount of material rendered useless by way of wear, it is startling! Lots of materials ranging from Antimony to zinc, including titanium, vanadium, iron, carbon, copper, aluminum etc., would be lost. It is therefore essential to conserve the natural resources through reduction in wear. Lubrication plays a vital role in our great and complex civilization. 1.2 BEARINGS A bearing is machine part, which support a moving element and confines its motion. The supporting member is usually designated as bearing and the supporting member may be journal. Since there is a relative motion between the bearing and the moving element, a certain amount of power must be absorbed in overcoming friction, and if the surface actually touches, there will be a rapid wear. 1.2.1 Classification: Bearings are classified as follows: 1. Depending upon the nature of contact between the working surfaces:- a) Sliding contact bearings b) Rolling contact bearings. a) SLIDING BEARINGS: Hydrodynamically lubricated bearings Bearings with boundary lubrication Bearings with Extreme boundary lubrication. Bearings with Hydrostatic lubrication. b) ROLLING ELEMENT BEARINGS: .
