YDTech® manufacturer of precision tapered rollers and tapered roller bearings! Supplier of loose tapered rolling elements in china.
tapered rollers as an rolling elements for tapered roller
bearing. bearings consist of components: inner/outer ring;
the cup; the tapered rollers; and the cage.
tapered roller gauge value in the same batch, with a
maximum average diameter of a single plane with the
smallest average diameter of a single plane, the difference between its
average diameter of a single plane.
SDw : basis of the end surface of a roller from the roller at 1.2 times the maximum chamfer dimensions, and
the center line of the circumference of the roller axis, each pitch on this circumference of a radial axial plane
of maximum and minimum distance poor.
tapered rollers radius of basis end facesSR: in either inside a roller axial plane, roller cone surface
intersection of the two Plain line extension line is center of
the sphere to the distance between the intersection and
reverie corners to make a spherical radius, spherical roller
benchmark is part of the end face , the radius of the
sphere is the basis of the end face of the radius, also
known as ball base radius.
regulation values of tapered rollersIn the middle of the length of the roller radial plane, the
average diameter of the roller single plane deviates from
the nominal diameter, the diameter of The lower deviation
defined deviation range.
tapered rollers nest hole diameter rollers allow the range of 40% to 55% of the diameter,
the other dimensions required by the provisions of Table 6, the cavity clean and free of
debris, regular shape, no obvious defects.
