Product Description

Product Description

Tapered roller bearings feature a cup and cone assembly. The cup is comprised of the outer ring and the cone assembly consists of inner ring, rollers, and cage. This bearing construction accommodates combined loads and provides low friction during operation.

We supply Single row tapered roller bearings, Double row tapered roller bearings, Four row taperedroller bearings.

Applications

Single row tapered roller bearings are typically used in applications with combined loads. Single row tapered roller bearings can also be used in sets. Single row tapered roller bearings can be matched face-to-face, back-to-back or in tandem to deliver specific advantages depending on operating conditions. 

Double row tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills and machines in the mining industry.

Four row tapered roller bearings are used almost exclusively in work roll applications such as rolling mills.

Product Parameters

Technical specification

Four Row Tapered Roller Bearings are mainly used in the bearing configuration of rolling mills with low to medium rolling speeds. Because of its special design, the bearing can withstand the axial load in addition to the radial load that occurs in such applications. Four-row tapered roller bearing also has several different structures according to specific operating conditions.
