Description

Spherical Roller Thrust Bearings have become increasingly popular in recent years due to their high-quality design and efficiency in a wide range of applications. These bearings are commonly used in heavy-duty machinery, automotive and aerospace industries, where there is a need for high-speed rotation and precise, stable operation. As a leading manufacturer in China, we are proud to offer a comprehensive range of Spherical Roller Thrust Bearings, engineered to the highest quality standards.

Our Spherical Roller Thrust Bearings have been designed to provide a variety of features that make them stand out from the competition. One of the most important features is their ability to support high axial loads, along with a moderate radial load. This makes them a perfect choice for applications where high-level loads are placed on the bearing. Additionally, these bearings are self-aligning, which means they can be used in applications where there is misalignment between the shaft and housing.

Our Spherical Roller Thrust Bearings are of the highest quality, thanks to the advanced techniques we use in the manufacturing process. We use only the best materials, ensuring that our products meet and exceed the standards set by international regulatory bodies. Our manufacturing processes are also closely monitored to ensure that we meet our quality standards, and we perform rigorous testing before any product is shipped.

One of the most significant benefits of choosing our Spherical Roller Thrust Bearings is their high durability. These bearings have been engineered to withstand harsh environments and extreme conditions, making them ideal for applications where the machine or equipment is exposed to high heat, dust, and other contaminants. This ensures that the bearings function smoothly and efficiently for an extended period of time, with minimal maintenance and repair cost.

Another significant advantage of our Spherical Roller Thrust Bearings is their versatility. We offer a wide range of designs and sizes to meet the needs of various applications. Whether you need a bearing for heavy-duty machinery, equipment used in chemical processing, or automotive application, our bearings are designed to suit your needs. We also offer customized solutions, allowing you to have bearings that meet your specific requirements.

Our Spherical Roller Thrust Bearings are also relatively easy to install, thanks to their durable design and high-quality materials. Whether you need a single bearing or a larger supply, our team of experts is ready to help you with the installation process. We offer installation support and guidance, ensuring that the bearings are correctly installed and functioning.

In summary, our Spherical Roller Thrust Bearings are designed to meet the most demanding applications. With their high load capacity, self-aligning ability, and durability, they offer an efficient and cost-effective solution for most industrial and automotive applications. We are proud to offer a comprehensive range of Spherical Roller Thrust Bearings that are engineered to meet and exceed international standards. Contact us today to learn more about our range of products and how we can help you meet your needs.

● Introduction

Spherical roller thrust bearings consist of a shaft washer, a race and a set of asymmetric spherical rollers. The bearing is a separable roller bearing. The cage includes the shaft washer and the spherical roller into a component. The seat ring and the component can be separated, the inner and outer rings can be installed independently. The action line of the rolling element load and the bearing axis obliquely form a certain contact angle, which can bear heavier axial load and radial load, but the radial load shall not exceed 55% of the axial load. The spherical thrust bearing has self-aligning performance, which allows the relative inclination of the shaft washer and the seat washer, which can compensate for misalignment, deflection of the shaft and deformation of the bearing seat. When the bearing bears one-way axial load, it can limit the one-way axial displacement of the bearing, so it can be used for one-way axial positioning. The spherical roller thrust bearings has large bearing capacity, small relative sliding, and high allowable speed. It needs oil lubrication when used.

Bearings are suitable for working at high speed, mostly used in oil drilling rig spindles, iron and steel making machinery, hydraulic generators, vertical motors, propeller shafts for ships, tower cranes, extruders, reducers for rolling screws in rolling mills, forming machines, etc.

● Bearing Series

The types of the bearings include 292 series, 293 series and 294 series.

● Production Details

◆ Quality requirements for the machined surface of bearing rings

1. After quenching, the roughness of the surface that does not need to be ground should meet the requirements of the enterprise standard.

2. After turning, no forging marks (black skin, cracks, etc.), burrs, acute angles, depressions, nicks, surface wrinkles (turning tool vibration marks, pits), deep scratches and material defects are allowed on the surface.

3. After soft grinding, the scratch depth of the non-reference end face does not exceed 1/3 of the total allowance, and the scratch depth of the reference end face does not exceed 1/4 of the total allowance. The surface that is not ground after quenching should not be ground. There should be no visible burns, bumps and other mechanical damage on the surface.

4. The marking quality of the ferrule must meet the requirements of national standards and industry standards.

◆ Bearing failure analysis method

1. Surface topography analysis methods: naked eye, macroscopic magnifying glass, stereo (or optical) microscope, scanning electron microscope (SEM) and transmission electron microscope.

2. Micro-area and surface composition analysis methods.

3. Structure, surface orientation and stress analysis: macroscopic stress analysis, microscopic stress analysis, phase structure analysis and crystal plane orientation analysis.

● Vibration of Bearings

During the operation of the rolling bearing, an elastic vibration system is formed due to the elastic contact between the raceway and the rolling elements. In addition, the forced vibration system caused by the manufacturing error of the bearing parts and the self-excited vibration system caused by the sliding between the bearing parts will cause the bearing vibration. In particular, when its vibrational energy is transmitted into the air, the noise of the bearing is formed. The vibration and noise levels of rolling bearings are a comprehensive reflection of the dynamic performance quality of the bearing.
