Design classification
1) The most basic and widely used tapered bearing, the single-row
type 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)
or preload condition to optimize performance
2) Double row tapered roller bearings can carry heavy loads and are
stiff. They are suitable for the accommodation of combined (radial
and axial) loads and can locate a shaft axially in both directions
with a given axial clearance or a given preload. Their main use is
in gearboes, hoisting equipment, rolling mills and machines used in
the mining industry, e. G. Tunneling machines
Double row tapered roller bearings are produced in two
configurations and in several different designs
