30203 Tapered Roller Bearing
DESIGN CLASSIFICATION
Single row tapered roller bearing is the most basic and widely used tapered bearing. It consists of the cone assembly and the cup. It is usually fitted as one of an opposing pair. During equipment assembly, single row bearings can be set to the required clearance (endplay) ro preload condition to optimize performance.
Double row tapered roller bearings can bear heavy load with great rigidity. They are suitable for bearing combined load (radial and axial) with certain axial clearance or preload. TDD and TDI are general.
DESIGN FEATURE
Easily installation. High radial and axial rated load.
Tapered roller bearings are generally separable. i.e. the cone consisting of the inner ring with roller and cage assembly can be mounted separately form the cup (outer ring). The projection lines at all the tapered surfaces meet at a common point on the bearing axis.
