Taper Roller Bearings

FRB BEARINGS Tapered roller bearings are a unique subset of axial roller bearings in which the rollers are tapered rather than straight right cylindrical. The roller shape allows thrust loads to be withstood in addition to the radial loads.

The inner and outer ring raceways and rollers of these bearings are made with a taper so that the surface planes of the raceways and roller axis meet at a point.The rollers are guided by a flange on the inner ring.Tapered roller bearings are separable, and have the following components: outer ring,inner ring and roller assembly. The non-separable inner ring and roller assembly is called the 'cone', and the outer ring is called the 'cup'. Internal clearanceis established during mounting by the axial position of the cone relative to the cup.

Roll-neck applications in rolling mills, transmissions gear reducers, geared shafting, steering mechanisms, and machine-tool spindles.Where speeds are low, grease lubrication suffices, but high speeds demand oil lubrication and very high speeds demand special lubricating arrangements.

Depending on the application, Taper Roller Bearings are divided into four types:

1.Single-row Tapered roller bearings

FRB BEARINGS producesSingle-row Tapered roller bearings are the most widely used tapered roller bearings. They have a high radial capacity and a thrust capacity about 60% of radial capacity. The exact percentage depends on the size of the tapered roller bearing. Variations within the type include tapered bores for frequent removal, pin cages and hollow rollers for higher capacity, and steep roller angles for higher thrust capacity.

2.Two-row Tapered roller bearings
FRB BEARINGS produces Double-row Tapered roller bearings can replace two single-row tapered roller bearings mounted back-to-back or face-to-face when the required capacity exceeds that of single-row tapered roller bearings. If the tapered roller bearing contact lines converge away from the bearing axis, the bearing is more tolerant to misalignment. If they converge toward the axis, the tapered roller bearing has higher resistance to moment loading, but lower tolerance for misalignment.

3.Four-row Tapered roller bearings
FRB BEARINGS produces Four-row Tapered roller bearings have characteristics similar to two 2-row tapered roller bearings mounted side-by-side. These tapered roller bearings are used to provide high capacity or to accommodate special mounting problems.

4.Inch Tapered roller bearings
FRB BEARINGS produces Inch Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at common point on the bearing axis. Their design makes taper roller bearings particularly suitable for the accommodation of combined (radial and axial)loads.
