Company Overview

In the field of tapered roller bearings, Timken's deep knowledge of metallurgy, tribology and mechanical power transmission helps improve the efficiency and reliability of equipment, machinery and vehicles around the world. Today, Henry Timken's vision of making the world run more efficiently and reliably is at the heart of Timken's business. In the 1890s, Henry Timken, a carriage maker in St. Louis, Missouri, USA, discovered that heavy freight carriages often had difficulty turning sharp corners. To solve this problem, he used a tapered roller bearing design that could withstand radial (weight) and axial (side reaction) loads. The results of this application were very exciting and brought many benefits to customers. First, this application made the carriage run smoother, reducing repair and replacement costs. In some cases, the bearings also improved the performance of the carriage, thereby reducing the number of mules and horses used. More importantly, smoother turns reduced the chance of lost goods. Henry Timken always had the interests of the customer in mind, and soon discovered that there were many other applications where tapered roller bearings could also improve equipment performance. Henry Timken and his two sons, HH Timken and William Timken, founded Timken Roller Bearing & Axle Company in 1899, laying the foundation for the global enterprise that keeps the world turning. Over the years, Timken has helped customers succeed with a clear corporate vision, industry focus, advanced processes and global expansion. From 1899 to today, Timken has continued to drive global industry. Henry Timken's patent for tapered roller bearings is the foundation on which Timken has been built. Since 1899, Timken has significantly expanded its product portfolio through innovation and acquisitions, while earning a high reputation by solving tough problems on Earth and in space. In the 1950s, automated high-volume bearing production had reached new speeds, driving Timken's production and profits to new levels, but Timken never stopped improving. In 2014, Timken introduced the DeltaX program, a major investment to accelerate product development and expand product lines. As early as the beginning of the 20th century, Timken entered the overseas market through a licensing agreement signed in the UK, and then achieved large-scale overseas expansion in the 1960s and the following decades. Today, Timken serves customers and markets around the world through a global network. Timken in China Timken entered the Chinese market in 1992. In China, Timken has not only established a strong business team, but also invested in the construction of manufacturing bases with global production or service capabilities.

Slewing Bearing Information

What is Slewing Bearing

A slewing bearing is a kind of large-sized bearing that can bear axial force, radial force and tilting moment simultaneously. It is mainly used in mechanical equipment that needs to rotate around a fixed axis, such as cranes, excavators, wind turbines, and radar antennas. It consists of an inner ring, an outer ring, rolling elements, and a retaining cage. The inner and outer rings have raceways, and the rolling elements are arranged between the raceways to achieve smooth rotation.

History of Slewing Bearing

The history of slewing bearings can be traced back to the early days of industrial development. In the past, simple rotary support structures were used in some large machinery, but with the continuous improvement of industrial technology and the increasing demand for large-scale and high-load machinery, the slewing bearing gradually emerged and developed. In the mid-20th century, with the development of materials science and manufacturing technology, the performance and quality of slewing bearings were continuously improved, and they were widely used in various fields.

Purpose of Slewing Bearing

The main purpose of slewing bearings is to provide support and rotation function for large mechanical equipment. It can enable the equipment to rotate smoothly around a fixed axis, and at the same time bear various loads during the rotation process, such as axial load, radial load and tilting moment. In different application fields, the specific functions of slewing bearings are also different. For example, in cranes, slewing bearings are used to realize the rotation of the boom; in wind turbines, they are used to support the rotation of the rotor.

Principle of Slewing Bearing

The working principle of slewing bearings is based on the rolling friction between the rolling elements and the raceways of the inner and outer rings. When the inner or outer ring is subjected to an external force, the rolling elements roll in the raceways, thereby realizing the relative rotation between the inner and outer rings. The design and selection of rolling elements, raceway shapes and materials have a direct impact on the performance and load-bearing capacity of slewing bearings.

Features of Slewing Bearing

High load-bearing capacity: It can bear large axial, radial and tilting loads, meeting the requirements of heavy-duty machinery.

Double-row ball slewing bearings: It has two rows of balls, which can bear larger axial and radial loads. It is widely used in cranes, excavators and other equipment.
Single-row crossed roller slewing bearings: The rollers are arranged in a crossed manner, which can bear large radial and tilting moments. It is often used in high-precision and high-load applications.
Double-row tapered roller slewing bearings: It can bear large axial and radial loads, and has good rigidity and accuracy. It is suitable for heavy-duty machinery.

Precautions for using Slewing Bearing

Proper installation: Follow the installation instructions carefully to ensure that the slewing bearing is installed correctly. Improper installation may cause uneven load distribution and affect the service life of the bearing.
Regular lubrication: Regularly add lubricating oil or grease to reduce friction and wear between the rolling elements and the raceways. The type and quantity of lubricants should be selected according to the working conditions of the bearing.
Sealing protection: Ensure the sealing performance of the slewing bearing to prevent dust, water and other impurities from entering the bearing, which may cause damage to the rolling elements and raceways.
Overload prevention: Do not exceed the rated load of the slewing bearing to avoid damage to the bearing structure and reduce its service life.
Regular inspection: Regularly check the operation status of the slewing bearing, including the rotation accuracy, noise and vibration, and deal with problems in a timely manner.[!--empirenews.page--]

Things to consider when purchasing Slewing Bearing

Load requirements: According to the actual working conditions of the equipment, accurately calculate the axial, radial and tilting loads that the slewing bearing needs to bear, and select a bearing with appropriate load-bearing capacity.
Rotation speed: Consider the rotation speed of the equipment to ensure that the selected slewing bearing can meet the requirements of rotation speed and has good stability at high speeds.
Accuracy requirements: If the equipment has high requirements for rotation accuracy, select a slewing bearing with high accuracy grade.
