increased load capacity

Single row tapered roller bearings can be supplied matched in “DB” or “DF” arrangement. These matched bearings are manufactured so that, when mounted opposite each other, the pair should have an established initial axial clearance and a uniform distribution of the loading. Matched bearings are used when the load carrying capacity of a single bearing is insufﬁcient, or when the thrust loads have to be carried at a certain axial clearance in both directions.

Dimensions in accordance with ISO 355-2007

Tapered roller bearings are designed to take radial and thrust loads from one direction.

They consist of the inner race (cone), with cage guided rollers, and the outer race (cup).

The track has the same profile as the tapered rollers. The extension of the contact lines

meet at a common point on the bearing axis of rotation. The cone and cup are

seperable. By using two bearings as opposed mountings, they can carry thrust loadings

in both directions.

Single row tapered roller bearings can be supplied matched in “DB” or “DF”

arrangement. These matched bearings are manufactured so that, when mounted

opposite each other, the pair should have an established initial axial clearance and a

uniform distribution of the loading. Matched bearings are used when the load carrying

capacity of a single bearing is insufficient, or when the thrust loads have to be carried at

a certain axial clearance in both directions.

Axial clearance

The axial clearance of single tapered roller bearings is adjusted on assembly. With matched bearings, as with double and 4 row bearings,

axial clearance is achieved by the addition of spacer rings ground to give the required clearance. Radial clearances for double

and four row tapered roller bearings are shown in the technical section. The radial clearance is transformed into axial clearance by the

following relation:

Axial clearance = Radial clearance / 2 tan a

a = contact angle between rollers and the outer ring raceway
