The role of tapered roller bearings

Update:2018-03-12

Tapered roller bearings are mainly subjected to radial and axial combined load. The bearing bearing capacity depends on the raceway angle of the outer ring. The larger the angle, the greater the bearing capacity. This type of bearing is a separate type bearing and is classified into single row, double row and four row tapered roller bearings according to the number of rows of rolling elements in the bearing. The single-row tapered roller bearing clearance needs to be adjusted by the user during installation; double-row and four-row tapered roller bearing clearances are already specified according to the user's requirements at the time of shipment, and do not require user adjustment.
Tapered roller bearings have a conical inner ring and an outer ring raceway with tapered rollers arranged in between. The projection lines of all cone surfaces converge at the same point on the bearing axis. This design makes the tapered roller bearing particularly suitable for supporting composite (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the α angle, the higher the axial load capacity. The size of the angle is expressed by the calculation coefficient e; the greater the value of e, the greater the contact angle, the greater the applicability of the bearing to axial loads.
Tapered roller bearings are usually of a separate type, ie a cone inner ring assembly consisting of an inner ring with a roller and cage assembly can be mounted separately from the outer ring of the cone.
Tapered roller bearings are widely used in the automotive, rolling mill, mining, metallurgy, plastics machinery and other industries.
