Characteristics of Tapered Roller Bearings

Characteristics of Tapered Roller Bearings

Before buying tapered roller bearings, it is necessary to know the relevant knowledge of original crime stick bearings. This paper will introduce the characteristics and classification of tapered roller bearings so that users can better buy tapered roller bearings.

Tapered roller bearings belong to separate type bearings. Both inner and outer rings of bearings have tapered raceways. The bearing can be divided into single row, double row and four row tapered roller bearings according to the number of rollers installed. Single row tapered roller bearings can withstand radial load and unilateral axial load. When bearings are subjected to radial loads, there will be an axial component, so another bearing that can withstand the reverse axial force is needed to balance it.

Tapered roller bearings can be divided into: single row tapered roller bearings, double row tapered roller bearings, four row tapered roller bearings.

Single row tapered roller bearings have an outer ring, and its inner ring and a group of tapered rollers consist of an inner ring assembly enclosed by a basket cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing profile size standard, the outer ring or inner ring assembly of any standard tapered roller bearing should be able to achieve international interchange with the same type of outer ring or inner ring assembly. The outer ring (or inner ring) of double row tapered roller bearings is a whole. Two inner rings (or outer rings) have similar small end faces, with spacers in the middle. The clearance is adjusted by the thickness of spacers. The thickness of spacers can also be used to adjust the pre-interference of double row tapered roller bearings.

Four-row tapered roller bearings have the same performance as double-row tapered roller bearings, but they bear larger radial load and lower limit speed than double-row tapered roller bearings. They are mainly used in heavy machinery.
