Product introduction
30317 Taper Roller Bearing is a type of rolling-element bearing used to
support radial and axial loads in rotating machinery. It is
designed to handle both radial (perpendicular to the shaft) and
axial (parallel to the shaft) loads simultaneously.
(Make high-end bearings and sell them at factory prices)
The inner and outer rings have tapered raceways, which are
inclined to the bearing axis. The tapered rollers are arranged in a
way that their axes converge at a common point on the bearing axis,
creating a "cone" shape.
This design allows the rollers to transmit loads in a way that
produces a rolling motion, reducing friction and enabling smooth
rotation
