Double Row / Four Row Metric Size Tapered Roller Bearing 33122

Tapered roller bearing

Tapered roller bearing refers to radial thrust type rolling bearing with tapered roller rolling body. There are two kinds of small cone Angle and large cone Angle. Small cone Angle mainly bear radial load mainly radial and axial combined load, often in double use, reverse installation, inner and outer seat ring can be installed separately, radial and axial clearance can be adjusted during installation and use; The large cone Angle is mainly used to bear the combined axial and radial loads mainly based on axial loads. It is generally not used to bear pure axial loads alone, but can be used to bear pure radial loads when it is configured (the same end is installed relatively).

Tapered roller bearings belong to separation bearings, bearing inner and outer rings have tapered raceway. The bearings can be divided into single row, double row and four row tapered roller bearings according to the number of roller rows. Single row tapered roller bearings can withstand radial load and single direction axial load. When the bearing bears radial load, there will be an axial component, so when another bearing that can withstand the axial force in the opposite direction is needed to balance it.

The structure, assembly dimension accuracy and rotation accuracy of inch tapered roller bearings are different from those of metric bearings .It is mainly used for imported machinery or industries with special needs.

The inch tapered roller bearing refers to the tapered roller bearing whose overall dimensions are measured in inches , originated from Britain and the United States.
