Don’t Let That Large-Diameter Bearing Fail. Refurbish it First.

Bearings with diameters between 36 and 169 in. typically cost a lot and have long lead times, forcing end users to keep spare bearings on hand or face extensive downtime should a bearing fail. Therefore, it can make sense to replace a bearing before it degrades. Bearings removed this way often make good candidates for repair or refurbishment. But what qualifies a bearing as repairable? How are repairs carried out? And what kind of resul...

Avoiding bearing wear and damage during start-up and shut down

Massive rotors in hydroelectric generators, large ball mills, rolling mills, large electric motors, and steam and gas-turbine generators normally operate with great efficiency on oil films in sleeve and thrust bearings. But trouble arises when rotational speed is too low, as it is at starting and stopping, to generate a complete oil film. Then frictional drag and wear increase with metal-to-metal contact between the bearing and rotating...

Bearing Mounting

For instrument bearings, certain special considerations should be emphasized: Heavy press fits should be avoided. Accuracy of mounting surfaces should be equal to accuracy of mating bearing surface. Misalignment for low torque and running accuracy should not exceed 1/4°. Loading across the bearing during assembly should be avoided. Axial positioning: Accurate axial positioning of the shaft relative to the housing requires shoulder...

Bearing Speed
Bearing knowledge / 2019-08-01

Limiting speed values for instrument bearings are almost impossible to determine. However, generalizations may be made. Bearing size: Highest speeds may be obtained with the smallest bearing. However, extremely small miniature bearings usually have a thin, weak retainer and their maximum speed is less than medium-size miniatures. Load: Limiting speed is directly affected by the magnitude of applied load. Heavy loads result in ...

Bearing Heat
Bearing knowledge / 2019-07-31

Heat is generated either by shearing of the oil film or by rubbing contact. In hydrostatic and hydrodynamic bearings, heat generation at running speeds is the result of oil shear, and the amount of temperature rise can be estimated if oil viscosity and shear rates are known. Temperature can be regulated by controlling the oil flow through the bearing or by using external cooling. Heat is generated either by shearing of the oil film or b...

Bearing Torque
Bearing knowledge / 2019-07-30

Bearing torque is the moment required to overcome internal friction to start or maintain rotation of one ring while the other is stationary. Torque or friction generally increases when: Bearing size is increased because a larger ball and retainer must be moved. Load is increased because of greater deformation and resistance to rolling motion. Speed is increased because of increased lubricant drag. Lubrication type is a critical torque f...

Bearing Loads
Bearing knowledge / 2019-07-29

In some applications, allowable load seriously influences selection. Major variables affecting load capacity are ball size and number and internal geometry of the bearing.
