Rolling Contact Bearing

Double row angular contact ball bearings can bear radial load and axial load at the same time. It can work at higher speeds. The larger the contact angle, the higher the axial load-carrying capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.

High-temperature resistance, durability, high ductility
The material of the deep groove ball bearing is GCr15, which has wear resistance, high-temperature resistance, and high ductility.

Low noise, high speed
Use noise measurement equipment to test the bearings, and use brand-name lubricants to make the bearings run at high speed and stable

What Is a Rolling Contact Bearing?

A rolling contact bearing is a type of bearing that has an inner and outer race between which metal balls or rollers roll. These balls or rollers then rotate smoothly against each other.

They are usually made from stainless steel or aluminum alloys. They are used in a variety of industries.

Rolling contact bearings have several different components that work together to make them function properly. Rings (races), rolling elements, and cages all help to allow a bearing to rotate stably and smoothly.

When a bearing’s rings rotate, they cause the rolling elements to roll. Without a cage in place, this can create a problem because the rolling elements will come into contact with each other and disrupt the rolling motion.

This is why cages are necessary to keep the rolling elements separated. This allows them to roll smoothly and reduces friction.

Cages are often made of steel or polyamide plastic, depending on the application and environment in which the bearing will be placed. The cages also serve to secure the balls within the bearing, preventing them from shifting around and reducing friction.

The lubrication of a bearing is another very important component that keeps it functioning properly. Using the correct lubricant helps to minimize friction in the rolling motion and prevent abrasion from occurring.

The design of rolling contact bearings includes selecting the correct size and material for the application. The size and materials are determined based on the load-carrying capacity for static loads and dynamic loads as well as the required service life.

A common type of rolling element bearing is the ball bearing. It consists of round metal balls or rollers that move between a fixed and rotating race.

These bearings can handle radial or axial loads as well as heavy shock loads. They are available in bore dimensions ranging from 20 mm to 900 mm.

They can also be designed to handle misalignment and shaft deflection. They can be sleeved or mounted with a retainer. They are usually made of steel, but they can be made from other materials as well. The lifetime needed for a bearing depends on the application and can be extended by cooling, lubrication, and sealing. The materials used for the bearing need to be free of microscopic defects.

Bearings are a vital part of modern equipment and machinery. They reduce friction, allow for different types of loads to be carried and ensure that machine components are stable during operation.

To maintain these qualities, a variety of materials are used in the manufacturing of rolling contact bearings. These include chrome steel, carbon steel, and stainless steel.

Among these materials, chrome steel is the most common. It is mainly composed of carbon and contains 1.5 percent chromium, which allows for corrosion resistance and increased hardness levels when it undergoes controlled processing methods.

It is also highly resistant to bending stresses and fatigue cracking due to its high core toughness level. However, it may be susceptible to abrasion, fatigue, and pressure-induced welding when used in applications where the bearing elements have to be pressed together repeatedly.

Unlike stainless steel, carbon steel is cheaper to manufacture and has a lower melting point. It can handle less heavy loads, but it is less ductile and can be difficult to operate at high speeds.

A rolling contact bearing is an integral component of most mechanical machines. It reduces friction, heat generation, and wear and tear by replacing sliding motion with low-friction rolling.

Rolling contact bearings are used to support a rotating shaft resisting radial and axial loads, and they are available in a wide variety of designs. They may be self-aligning or non-self-aligning, depending on the type.

The life of a rolling contact bearing is typically determined by a combination of operating speeds and load. Under these conditions, the calculated life is normally a minimum of one million revolutions.

The three usual limits to the lifetime or load capacity of a ball, roller, or race are abrasion, fatigue, and pressure-induced welding. These problems are caused by the microscopically rough surface of these components, which deforms slightly under abrasion and stresses when pressure-induced welding occurs. It is these flattened spots that degrade the lubricant and cause wear and damage to the rolling elements.
