Classification of tapered roller bearings
Aug 12, 2018

A single row of tapered roller bearings has an outer ring, its inner ring and a set of tapered rollers made from a basket holder. The outer ring can be separated from the inner ring components. According to the ISO taper roller bearing profile and size standards, any standard type of taper roller bearing outer ring or inner ring components shall be internationally interchangeable with the same type of outer ring or inner ring components. That is, the outer ring of the same model should conform to ISO492(GB307) in addition to the external size and tolerance, the cone Angle of the inner ring component and the cone diameter of the component must also meet the relevant provisions of the interchange.

Usually, single row tapered roller bearing outer ring raceway of cone Angle between ° ~ 10 ° 19, able to withstand the axial load and radial load combination. The larger the cone Angle, the greater the ability to withstand axial loads. Big cone Angle of the bearing, post code to add B, Angle between 25 ° ~ 29 °, it can withstand large axial load. In addition, single row tapered roller bearings can adjust the size of the clearance during mounting.

The outer ring (or inner ring) of a double row tapered roller bearing is integral. The two inner rings (or outer rings) are close to each other on small ends, and the clearance is adjusted by the thickness of the spacer, or the thickness of the spacer can be used to adjust the preload of double-row tapered roller bearings.

Four-row tapered roller bearings, the performance of this bearing and double-row tapered roller bearings are basically the same, but than double-row tapered roller bearings to withstand greater radial load, limit speed slightly lower, mainly used for heavy machinery.

Multi - seal double - and four-row tapered roller bearings, ZWZ provides long - life, multi - seal double - and four-row tapered roller bearings. The bearing is designed in a new and personalized way, and the traditional design method of the fully sealed bearing is changed. Compared with the open-type structure bearing, the multi-seal double and four-row tapered roller bearing can increase its life by 20%~40%. Reduce lubricant consumption by 80%.
