Tapered Roller Bearing from China
The inner and outer ring raceways are segments of cones and the rollers are also made with a taper
so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a
common point on the main axis of the bearing.
This conical geometry is used as it gives a larger contact patch, which permits greater loads to be
carried than with spherical (ball) bearings, while the geometry means that the tangential speeds of
the surfaces of each of the rollers are the same as their raceways along the whole length of the and
no differential scrubbing occurs. This avoids rapid wear and greatly reduces. The rollers are guided
by a flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum.
The larger the half angles of these cones, the larger the axial force the bearing can sustain.
Thanks & best regards
