TAPERED ROLLER BEARINGS TYPES

● Single row bearings 

● Single row 

   This is the basic and the most widely used type of tapered roller bearing. It consists of the inner-ring assembly and the outer

   ring. 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.

● Single-row,with flanged outer ring 

   The is a variation on the basic single-row bearing. bearings have a flanged outer ring to facilitate axial location and accurately

    aligned seats in a through-bored housing.

● Double-row bearings 

● Double outer ring 

   This has a one-piece (double) outer ring and two single inner rings. It is usually supplied complete with an inner-ring spacer 

   as a pre-set assembly. This configuration gives a wide effective bearing spread and is frequently chosen for applications 

   where overturning moments are a significant load component. Bearings can be used in fixed (locating) positions or allowed

   to float in the housing bore, for example, to compensate for shaft expansion. TDOCD outer rings also are available in most 

   sizes.These outer rings have holes in the O.D. that permit the use of pins to prevent outer ring rotation in the housing.

● Double inner ring  

● Double inner ring with tapered bore

   Both comprise a one-piece (double) inner ring and two single outer rings. They are usually supplied complete with an 

   outerring spacer asa pre-set assembly. Bearings can be used at fixed (locating) positions on rotating shaft applications. For

   rotating housing applications, the double inner ring of type  can be used to float on the stationary shaft. has a tapered bore

   to facilitate removal when an interference fit is essential, yet regular removal is required.
