Rolling Contact Bearing
Rolling contact (plural rolling contacts)Â Any contact between rotating bodies such that the relative velocity of the two contacting surfaces is zero at the point of contact.
What are rolling contact bearings?
Rolling contact bearings are various bearings that use spherical balls or other types of rollers between fixed and moving elements. • The most common bearing types support rotating shafts and carry purely radial loads or a combination of radial and axial (thrust) loads.
What are the problems with rolling contact bearings?
Evidence of bearing issues appears in many forms, including:
Grooving: Contaminants wedged in soft cage material can incise grooves in rolling elements. …
Noise: Bearing damage can be distinguished by unusual yet characteristic noise using sound detection instruments during an operation.
Peeling: Caused by hairline cracks.
Rolling contact bearing and sliding contact bearing
What is a Bearing? A bearing (Sliding contact bearing or Rolling contact bearing) is a mechanical element which allows relative motion between two rotating parts, with minimum friction. An example of such rotating parts are shaft and its housing.
Application of rolling contact bearing
Some of the widely used applications of roller bearings are aviation cargo systems, engines, agriculture industry, heavy equipments and machinery, solar panels, medical equipments, automobile industry, power houses and many others.

What are the advantages of rolling contact bearings?
Advantages of Rolling Contact Bearings
Low starting and running friction except at very high speeds.
Ability to withstand momentary shock loads.
Accuracy of shaft alignment.
Low cost of maintenance, as no lubrication is required while in service.
Small overall dimensions.
Reliability of service.
Easy to mount and erect.
Rolling contact bearing are classified according to
Roller bearings on the other hand are classified according to the shape of the rollers:Â cylindrical, needle, tapered and spherical. Rolling bearings can be further classified according to the direction in which the load is applied; radial bearings carry radial loads and thrust bearings carry axial loads.
What is the most common bearing failure?
The majority of bearing failures occur because of improper lubrication. Lubrication failure can occur if the wrong lubricant is used, if not enough lubricant is applied, or if the bearing has been exposed to excessive temperatures that have caused the lubricant to degrade.
