Rolling Contact Bearing - ppt video online download

Rolling Contact Bearing - ppt video online download: Advantages 1. Low starting and low running friction. Low friction can be obtained in case of sliding bearing incase of the full film lubrication. It is possible in hydrostatic lubrication and it is very costly. 2. Ability to withstand momentary shock loads. 3. Accuracy of shaft alignment. 4. Low cost of maintenance, as no lubrication is required while in service. 5. Rolling bearing gives warning prior to failure, whereas sliding bearing failure is sudden and hence more dangerous compared to rolling bearing. 6. Reliability of service. 7. Easy to mount and erect. 8. Cleanliness. Disadvantages 1. More noisy at very high speeds. 2. Low resistance to shock loading. 3. More initial cost. 4. Design of bearing housing complicated.
