Tapered roller bearing
Detail

The tapered roller bearing belongs to separable bearing. The inner and outer rings of tapered roller bearings have tapered raceway. According to the roller rows, this type bearings include single-row, double-row and four -row. The single-row tapered roller bearing can bear radial load and axial load in one direction. When give radial load, the axial force formed inside the bearing must be offset. It is suggested that two of the bearings be put in face-to-face or back-to-back arrangements in application.


The sinlgle-row tapered roller bearing can bear axial load, and the capacity depends on the contact angle, that is the angle degree of outer raceway. The greater contact angle is, the bigger capacity will be. The single-row tapered roller bearing is very popular. The small size double-row tapered roller bearings are used on automobile wheels (fromer side). The four-row tapered roller bearing is used in large-size cold or hot rolling mill and heavy-duty machine.

The single-row tapered roller bearing has one outer ring,the inner ring and one set of tapered rollers are packed to a inner ring part by cage. The outer ring can seperate from the inner ring part. According to the ISO tapered roller bearing dimension standard, the outer ring and inner ring parts can be changed with the same model.

Usually, the tapered angle of outer ring raceway (on single-row tapered roller bearing) is in 10°~19°, can bear the axial load and radial load. The greater the tapered angle is, the capicity of axial load is bigger. The bearing with big tapered angle, the post code add B, the tapered angle in 25°~29°, this kind of bearing can bear large axial load. In addition, the clearance can be adjusted during installation.
