7 66140 Tapered roller bearings SKF
Single-row

Bearing series 302
Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers
are arranged. The projection lines of all the tapered surfaces meet at a common point on the
bearing axis. Tapered roller bearings are therefore particularly suitable for absorbing combined
loads (radial and axial at the same time). Because of their internal design, single row tapered roller
bearings cannot be used alone, but only together with a second bearing (figure 1) or as paired
bearings (figure 2).
Tapered roller bearings are generally not self-retaining. The inner ring with the rollers and cage can
be installed separately from the outer ring.
