32215 bearing has tapered inner and outer raceways between which tapered roller are arranged. The design of taper rollers makes them particularly suited to accommodating combined axial and radial loads. They are supplied as a cup and cone set (inner and outer).

Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements), and the cage (roller retainer). Tapered roller bearings are uniquely designed to manage both thrust and radial loads between a rotating and non-rotating member. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.

Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearings can withstand axial load in one direction and can limit axial displacement of the shaft or housing in one direction.
