Details:
1. Less coefficient of friction, High limiting speed, Large size range, Variations of structure.
2. Tapered Roller Bearings are designed such like cup. Cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis.
3. Single-row tapered roller bearing is able to carry radial and axial load in one directions simultaneously because an axial component of produced when this type of bearings loaded radically, two bearings are used together facing one another, or two or more bearings are matched and used.
Application:
For mounting wherever axial and radial loads are expected
For most parts for torque transmission
Home appliances, electric motors, automotive components
