The accuracy of industrial robots is a key factor directly related to product quality and production efficiency. Bearings are an important factor affecting the accuracy of industrial robots, and industrial robot bearings are required to have long lifespan, high stiffness, and low friction.Therefore, when selecting industrial robots, not only should their dynamic rated load be considered, but also the suitable values for each structural parameter should be carefully selected. The development of contemporary industrial robots is characterized by their lightweight and thinness.
Manufacturers of different brands of bearings may have their own strengths and expertise in different types of bearings. Here are some well-known imported bearing brands and their preferred bearing types:SKF (Sweden): SKF is a leading global bearing manufacturer, with products covering various types of bearings.
1. Correct mounting: Correct mounting is the first step to protect the bearing. Make sure you select the proper bearing type, the right amount of lubricant, and the correct mounting method. Follow the manufacturer's guidelines and recommendations to ensure that the bearing is properly installed and not over-pressurized or over-loosened. 2. Keep them clean: Bearings should always be kept clean. Prevent dust, dirt, liquids or other contaminants from entering the bearing. Clean the bearings regularly and make sure the surrounding environment is clean to avoid any possible damage.3.
When designing and manufacturing rolling bearings, the selection of bearing materials is generally based on the following principles.1、 Select according to the working conditions of the bearings①. Working temperatureBearings working at room temperature are made of chromium bearing steel. Chromium bearing steel is also used for working temperatures above 150 ℃ and below 250 ℃, but it needs to undergo special heat treatment (requiring tempering at 200 ℃ or 300 ℃).②.
Bearings are an important component in contemporary mechanical equipment, whose main function is to support the rotating body of the machinery, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling element, and retainer. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings.
(1) Based on the size and nature of the load     Large load or impact: Select roller bearings (line contact)     Low load or impact: ball bearing selection (point contact)(2) According to the direction of the load     Pure radial load: deep groove ball bearing, cylindrical roller bearing     Pure axial load: selective thrust bearing     Radial axial load: angular contact bearings, tapered roller bearings     Select deep groove ball bearings  when the axial load is not significant (3) Based on th
In addition to tapered roller bearings, deep groove ball bearings, outer spherical bearings, thrust bearings, and so on.Our company has developed and launched a new type of bearing - Trolley Bearings.It a non-standred type.We can customize according to your needs.Welcome your inquiry.
Recently, a large-scale international bearing exhibition was held in a large exhibition center. The exhibition attracted the participation of bearing manufacturers, suppliers, distributors and professionals from all over the world.Inside the exhibition center, various booths were set up with various types and specifications of bearing products, ranging from common deep groove ball bearings and cylindrical roller bearings to special customized bearings of various brands and models.
In Shanghai,the 2023PTC exhibition was held as scheduled.On October 24-27, the 2023 Asia International Power Transmission and Control Technology Exhibition (PTC ASIA) opened grandly at the Shanghai New International Expo Center. This exhibition highlights the theme of "digital intelligence empowerment, innovation and upgrading", with an exhibition area of nearly 100000 square meters, attracting over 1500 enterprises from multiple countries and regions such as Germany and Italy to participate. As a leading enterprise in the Chinese bearing industry, Renben,TIMKEN,etc.
The linear module affects the operation of many mechanical devices and is also one of the basic elements of the machine. Therefore, the quality of the linear module has a great influence on the operation of the machine. So how can you check the quality of a linear module?
