Besides metric design tapered roller bearings, there are also inch designbearings. For the cone assemblies and cups of inch design bearings, exceptfour-row tapered roller bearings, the bearing numbers are approximatelyformulated as follows:
For tapered roller bearings, besides single-row bearings, there are alsovarious combinations of bearings.
The cages of tapered roller bearings are usually pressed steel.

Two standard bearings are combined. The bearing clearances
are adjusted by cone spacers or cup spacers. The cones and
cups and spacers are marked with serial numbers and
mating marks. Components with the same serial number can
be assembled referring to the matching symbols.
The KBE type is a back-to-back arrangement of bearings with
the cup and spacer integrated, and the KH type is a face-to-
face arrangement in which the cones are integrated. Since
the bearing clearance is adjusted using spacers, it is
necessary for components to have the same serial number
for assembly with reference to matching symbols.

CYLINDRICAL ROLLER THRUST BEARINGS
These are thrust bearings containing cylindrical rollers. They can sustainonly axial loads, but they are suitable for heavy loads and have high axialrigidity.
The cages are machined brass.
SPHERICAL THRUST ROLLER BEARINGS
These are thrust bearings containing convex rollers. They have a self-aligning capability and are free of any influence of mounting error or shaftdeflection. Besides the original type, the E type with pressed cages for high
load capacity is also available. Their bearing numbers are suffixed by E.For horizontal shaft or high speed application, machined brass cages are
recommended. For details, contact NSK.Since there are several places where lubrication is difficult, such as the area
between the roller heads and inner ring rib, the sliding surfaces between cageand guide sleeve, etc., oil lubrication should be used even at low speed.
The cages in the original type are machined brass.
