SKF production tapered roller bearings have various designs and size to fit for multiple purposes. They can be divided into the following categories:

- single row circular cone roller bearings (figure 1),
-- matching single row circular cone roller bearings (figure 2),
- double row circular cone roller bearings (figure 3), and
-- four row circular cone roller bearings (figure 4).

Below in the corresponding section four points under the title that these bearings.

SKF is made based on circular cone roller bearings with seal, grease and adjustment of the bearing unit, for example

-- passenger auto-hub bearing unit (FIG. 5),
- trucks, wheel hub bearing unit (FIG. 6), and
Railway vehicle - with tapered roller bearings unit (figure 7).

Design features
Taper roller bearings taper has inner ring and outer groove, tapered roller are arranged in between. All lines of conical surface projection of the same point in bearing axis. This design makes tapered roller bearings specially suitable for composite (bear radial and axial load). Axial load bearing capacity is mostly decided by the contact Angle (figure 8), Alpha Angle, the greater the axial load capacity is higher (FIG 9). By calculating coefficients of Angle size to e, E, the greater the contact Angle, bearing the applicability of the axial load.

Taper roller bearings are usually separated type, namely the belt roller and maintains a component within the circle of inner cone circles with conical outer (components can separate inner).

SKF tapered roller bearings with logarithmic contact, in the shape of roller/groove interface provides the best stress distribution. Guide roller main sliding flange and special design, the surface will significantly promote roller surface/flange contact surface oil film formation. And benefits, including the operation reliability of reduced sensitivity.
