Clearance ratio should be increased for bearings of diameter less than

Explanation:

Clearance

• The effects of varying dimensions and clearance ratios are very significant in a bearing design.
• The radial clearance c as shown in the figure is contingent to some extent on the desired quality.
• Suitable values to be used for radial bearing clearance rely on factors that include materials, manufacturing accuracy, load carrying capacity, minimum film thickness, and oil flow.
• Furthermore, the clearance may increase because of wear.
• The clearance ratio (c/r) typically varies from 0.001 to 0.002 and occasionally as high as 0.003.
• It would seem that large clearance increases result in a decrease in minimum film thickness.
• Clearance ratio should be increased for bearings of diameter less than 0.1 m
