Tapered Roller Bearing 32021 2007121

Taper roller bearings are designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer.

Physical Characteristics:
(1).Taper roller bearings have tapered inner and outer ring raceway between which tapered rollers are arranged.
(2).Three projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes taper roller bearing particular accommodation of combined (racial and axial) loads.
(3).The axial load carrying capacity of the bearings is largely determined by the contact angle.
(4).Taper roller bearing has the logarithmic contact profile that provides for optimum stress distribution over the roller/raceway/contacts.
(5).The special design of the sliding surfaces of the guide flange and large roller ends considerably promotes lubricant film formation in the roller.
