30232JR Tapered Roller Bearing

Single row bearings can bear radial load and unidirectional axial load, and double row bearings can bear radial load and bidirectional axial load.Suitable for bearing heavy load and shock load. According to the different contact Angle (α), it can be divided into three types: small cone Angle, middle cone Angle and large cone Angle. The larger the contact Angle is, the greater the axial load capacity is. Outer ring and inner assembly (inner ring and roller and cage assembly) can be separated for easy assembly and disassembly. Bearings with rear auxiliary code "J" or "JR" have international interchangeability.

What is a taper roller bearing used for?

Tapered Roller Bearings are designed to reduce friction and, in turn, reduce the heat that can cause bearing structures to fail. This bearing is used in many industrial applications and is optimal for those undergoing excess loads.

Tapered roller bearings contain an inner ring, outer ring, and a number of tapered rollers. Looked at individually, the inner and outer bearing rings are also tapered, resembling a cone segment. Due to the large surface area contact, tapered roller bearings are able to withstand heavy axial and radial loads.

The most common material for ball bearing, roller bearing, and tapered roller bearing is chrome SAE 52100 bearing steel. This bearing can be made by high carbon content of 1.5% and has Rockwell hardness of about 64 HRC.

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.
