Tapered Roller Bearing Set

Tapered Roller Bearing set 749A-742
The inner and outer ring raceways and rollers of this type of bearing are made with a taper so that the planes of
the surfaces of the raceways and roller axis meet at a point. The rollers are guided by the cone (inner ring). A single row Tapered roller bearing can support a combined radial and axial load. If either a radial load or bi-directional axial load is to be carried, a pair of bearings must be used in a “face-to-face” or “back-to-back” position.
Tapered roller bearings are separable into the components: outer ring = cup, inner ring, and roller assembly = cone. The non-separable inner ring and roller assembly is called the “cone”, and the outer ring is called the “cup”. Internal
clearance is established during mounting by the axial positioning of the cone relative to the cup.
This bearing type can be used in a preload situation to obtain higher rigidity and better running accuracy of the
shaft. We sell most of the tapered rollers made, if you don't see your sizes, please contact us.
