The rolling body is a centripetal rolling bearing with cylindrical rollers. The internal structure of cylindrical roller bearings adopts rollers arranged in parallel, with spacer keepers or isolation blocks between the rollers, which can prevent the tilting of the rollers or mutual friction between the rollers, effectively avoiding the increase of rotating torque.
Single row cylindrical roller bearings are usually only subject to radial force, compared with the same size ball bearings, radial load carrying capacity increased 1.5-3 times, good rigidit; comparedy, impact resistance, it is particularly suitable for rigid support, but also support for short shafts, thermal elongation caused by axial displacement of the shaft and the installation and dismantling needs to be separated from the type of bearing of the machine accessories.
It has two rows of cylindrical roller and can withstand larger radial load; compared with single-row cylindrical roller bearings, the bearing capacity is stronger and has better rigidity; with higher rotary accuracy and lower coefficient of friction, it can ensure smoother operation.
Single-row full complement cylindrical roller bearing is a type of cylindrical roller bearing. Its main features include having a large number of cylindrical rollers closely arranged in the bearing, which can withstand large radial loads; line contact between the rollers and the raceway; strong load carrying capacity; due to the full complement of rollers, it has a higher load carrying capacity under the same size; the structure is relatively simple, and the operation is relatively smooth.
Double Row Full Complement Cylindrical Roller Bearings are cylindrical roller bearings designed to carry heavy loads. It has an extremely high load-carrying capacity compared to conventional type bearings with cages at the same width and a small radial cross-section to save space.
Sealed Double Row Full Complement Cylindrical Roller Bearings is a sealed structure added on the basis of double row full complement cylindrical roller bearings, which can effectively prevent external pollutants, water vapor and other harmful substances from entering into the bearing interior, thus improving the service life and reliability of the bearings.
Cylindrical roller bearings are widely used in machinery manufacturing, metallurgy, petroleum, chemical industry, electric power, aviation, shipping, rail transportation and other fields. In industrial production, their applications are very wide, such as: lifting equipment, wheeled excavators, metallurgical machinery, oilfield drilling rigs, hydropower machinery, ships, high-speed trains and so on.
Thrust cylindrical roller bearings can be dismantled into thrust cylindrical roller and cage assemblies, shaft rings and seat rings. These bearings can withstand very large axial loads in one direction but not radial loads, and they have no self-aligning capability.
Automobile engines, transmissions, differentials and wheel axles, cranes, excavators, drilling rigs and other heavy machinery, etc.
QJ218-N2-MA belongs to a four-point contact ball bearing. It has an inner diameter of 90mm, an outer diameter of 160mm, a thickness of 30mm, a single-row bearing with locating grooves, a solid brass cage and an outer ring guide.
There are countless brands of linear motions, and it is often difficult to choose when purchasing. Today we will take stock of the characteristics of the world's 10 ten linear motion brands. Understanding these brands will help you make targeted choices.
Bearings, as one of the key components of mechanical equipment, their normal operation is critical to the performance and life of the equipment. However, when abnormal sounds occur in bearings, it often signals potential problems and failures. In this essay, we will discuss in depth the causes, effects and coping strategies of abnormal bearing sounds.
Our Shandong Tefule Bearing Factory is located in the Bearing Industry Base of Liaocheng, Shandong Province. It is committed to the production and creation of automotive bearings and agricultural machinery bearings.
The ABEC grading system uses odd numbers - 1, 3, 5, 7, and 9 - as classification levels. The five different grades are listed in descending order of tolerance.
Automotive bearings, as critical components, play an integral role in the performance and reliability of vehicles.
Different choices of bearing materials will bring different performances to the bearing itself. Please follow us below to learn about the material knowledge of bearings and explore their different properties and applications.
