SKF Tapered Roller Bearing 32008

The inner and outer ring Rare Segments of cones and the rollers are tapered

and the roller axes if Projected,

would all meet at a common point on the main axis of the bearing.

This Geometry makes the motion of the cones remain coaxial,

with no sliding motion between the Raceways and the outside Diameter of the rollers.

This conical Geometry creates a linear contact patch.

which have point contact.

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 contact patch and no Differential Scrubbing occurs.

The larger the half angles of these cones the larger the axial force that the bearing can sustain.

Tapered roller Bearings are Separable into a cone Assembly and a cup.

The Non-separable cone Assembly Consists of the inner ring, the rollers, and a cage that retains and evenly spaces the rollers.

The cup is simply the outer ring.
