Taper Roller BearingROWISS offers the most extensive line of tapered roller bearings in the world. Tapered bearings consist of four interdependent components: the cone (inner ring), cup (outer ring), tapered rollers (rolling elements) and cage (roller retainer). They manage both thrust and radial loads on rotating shafts and are available in three
configurations:
Single-row Tapered Roller Bearings: Most basic and widely used tapered bearing. Usually fitted as one of an opposing pair. During equipment assembly, can be set to the required clearance (end play) or preload condition to optimize performance.
Double-row Bearings: Two-row tapered bearing arrangements offer increased load capacity over single types.
Four-row Bearings: Combine the inherent high-load, radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings into assemblies of maximum load rating in a minimal space.

FEATURES OF TAPERED ROLLER BEARINGS
The inner ring assembly of a tapered roller is referred to as the cone, while the outer ring is called the cup.
Tapered rollers are guided by the cone back face rib.
This bearing design is suitable for heavy radial loading and a sizeable amount of axial loading.
The taper of the rollers and the cone raceways have a common apex on the bearing axis.
The angle between the cup raceway and the bearing axis is the contact angle.
The larger the contact angle the greater the bearings axial load capacity.
The cone and cup are separable simplifying bearing mounting.
Single row bearings can accommodate radial load and axial load in one direction.
Two single row bearings are used opposing each other to simplify setting of the proper clearance between the two rows.
The two row design can handle radial load and an axial load in either direction.
The two row design is available as a TDO (double outer race), or a TDI (double inner race).
Two row taper designs are normally supplied with spacers to provide a pre-adjusted assembly.
The four row design is commonly used on rolling mill roll necks for their large load carrying capacity.
Cages used can be a pressed steel or a pin type.
