Single Row Tapered Roller Bearings (Inch Series)

Single Row Tapered Roller Bearings (Inch Series)

HM321245/HM321210

Description

Product Description:
Single row tapered roller bearings can bear radial load and single direction axial load. When the bearing bears radial load, it will produce an axial component force, so another bearing that can bear the axial force in the opposite direction is needed to balance it.
The single row tapered roller bearing has an outer ring, its inner ring and a set of tapered rollers are enclosed by a basket-shaped cage to form an inner ring assembly. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing outline dimension standard, the outer ring or inner ring assembly of any standard type of tapered roller bearing should be able to achieve internationality with the outer ring or inner ring assembly of the same model. exchange. That is to say, in addition to the external dimensions and tolerances of the outer ring of the same model, which must comply with the requirements of ISO492 (GB307), the cone angle and component cone diameter of the inner ring components must also comply with the relevant regulations for interchange.

use:

Tapered roller bearings are widely used in industries such as automobiles, rolling mills, mining, metallurgy, and plastic machinery.
