Product Overview
This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). It is typically mounted in opposing pairs on a shaft.
Tapered Roller Bearing is composed of an inner ring, outer ring, and tapered rolling elements, bearings can withstand combined loads (axial and radial). In addition, this design allows rolling movement without the rollers slipping off the tracks of the outer and inner rings.
The contact angle of the tapered roller bearings on the rolling tracks is variable, which in each case offsets the application axial and radial loading ratio; at a larger angle, greater ability to withstand axial loads.
Used to moderate speed and heavy-duty applications where durability is required its main aircraft application is the Wheel Assembly.
