Introduction

Double row tapered roller bearing is a widely used rolling bearing, which mainly consists of four parts: inner ring, outer ring, roller, and cage. Its rolling body is conical, and the angle formed by the inner and outer conical surfaces is called taper, usually 1:12 or 1:30. This design enables double row tapered roller bearings to withstand large radial and axial loads, and can be used in high-speed rotation and heavy load situations.

The advantages of double row tapered roller bearings include:

1. Strong ability to withstand high radial and axial loads, suitable for applications under heavy and impact load conditions.

2. Easy installation and maintenance.

3. Able to maintain good stability during high-speed operation.

4. It has adjustable axial clearance.

5. Capable of withstanding loads in two directions, with flexible and diverse usage.

The application range of double row tapered roller bearings is very wide, including various fields such as steel, mining, machinery, automobiles, aviation, etc. It is most widely used in industries such as machine tools and automobiles.

It should be noted that during installation, the alignment between the inner cone surface and the roller end face must be maintained to reduce the contact stress between the roller and the inner and outer circles. For harsh working environments, it is necessary to use high-quality bearings and lubrication devices to ensure their stability and durability. For example, for situations with high friction and high requirements for smooth operation, high-quality lubricating materials such as calcium based grease or lithium based grease should be used.
