Tapered Roller Bearing

Tapered roller bearings are designed such that the outer ring, inner ring, and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis.
Along with metric series bearings, inch series bearings are also available.
This type of bearing is suitable for applications that involve heavy or impact loading.

About Single-Row Tapered Roller Bearings

Able to carry radial and axial load in one direction simultaneously.
Because an axial component of force is produced when this type of bearing is loaded radially, two bearings are used together facing one another, or two or more bearings are matched and used.
There are standard, medium, and steep types that are different in contact angle size.
Medium-tapered metric series bearings are identified by the supplementary code "C" which is added as a suffix to bearing numbers.
Bearings whose outer ring width, outer ring small inside diameter, and contact angle are determined in accordance with ISO 355 specifications are identified by the supplementary code "J" as a suffix.
Inner ring assemblies and the outer rings of such bearings are interchangeable with those of bearings produced abroad if the bearing numbers are the same.
