30300 Series Tapered Roller Bearing

Tapered roller bearing is a kind of separated bearing, there being each a tapered raceway on inner & out ring and rollers are tapered. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The roller axes if projected, would all meet at a common point on the main axis of the bearing. This geometry makes themotion of the cones remain coaxial, eliminating sliding motion in the bearing. According to the column numbers of the roller, Tapered roller bearing can be divided into single row, double row and four row tapered roller bearing.

In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction. Applications for tapered roller bearings are commonly used for moderate speed, heavy duty applications where durability is required. Common real world applications are in agriculture, construction and mining equipment, axle systems, gear box, engine motors and reducers, propeller shaft, railroad axle-box, differential etc.
