Roller Bearing

Antifriction bearings are

• oil lubricated bearings

• bush bearings

• ball and roller bearings

• boundary lubricated bearings

Rolling contact bearings as compared to sliding contact bearings have

• lower starting torque

• require considerable axial space

• generate less noise

• high friction

In an application, the bearing is subjected to radial as well as axial loads. Which type of rolling contact bearings you would suggest?

• cylindrical roller bearing

• needle roller bearing

• thrust ball bearing

• taper roller bearing

In an application, the bearing is subjected to radial as well as axial loads. Which type of rolling contact bearings you would suggest?

• angular contact bearing

• spherical roller bearing

• taper roller bearing

• any one of above three types

The rolling contact bearing is known as

• sleeve bearing

• thin film bearing

• antifriction bearing

• bush bearing

The balls of rolling contact bearings are made of

• case hardened steel

• plain carbon steel

• high carbon chromium steel

• free cutting steel

The rollers of rolling contact bearings are made of

• case hardened steel

• plain carbon steel

• high carbon chromium steel

• free cutting steel

Taper roller bearing is used to take

• only radial load

• only axial load

• only torque

• both axial and radial loads

Rolling contact bearings are classified according to

• a.) type of rolling element

• b.) direction of load

• c.) magnitude of load

• a and b

Ball and roller bearings in comparison to sliding bearings have

• more accuracy in alignment

• low starting and running friction

• small overall dimensions

• all of these
