3. Combined charge
In many real applications, bearings are subjected to both axial and radial loads simultaneously. Special types of bearings, such as angular contact ball bearings, are adopted to support such loads. Consider a car driving in a straight line. Radial loads are often exerted on the wheel bearings by their weight. However, at the moment of turning, there is an axial "thrust" load due to lateral forces pushing the wheel outward or inward along its axis.

Distribution of the elements of the landing
Rolling element: These elements can be balls or rollers. exchange data They are located between two surfaces that move relative to each other.

Inner and outer races: These hold the rolling elements together. These are circular tracks through which the rolling elements move.

Cage or retainer: Their purpose is to maintain correct spacing between rolling elements and prevent them from coming into contact with each other. This facilitates smooth operation.

Lubrication: Grease or oil is applied to the bearing to prevent friction and wear. The lubricant forms a protective film between the rings and rolling elements and minimizes metal-to-metal contact.

Seal: This is an important part of the bearing. It is essential for cleaning and maintaining the lubricant inside the bearing.

2RS have rubber seals on each side of the outer cover, which is a contact type of sealing. They are ideal for use in environments where moisture, dust and other contaminants are present.
ZZ have metal shields on both sides. They help block large particles and create less friction than rubber seals, making them more suitable for high speeds and better efficiency.
Types of bearings and their characteristics
1. Ball bearings
(i) Deep groove ball bearings:
These are the most common types of bearings. They consist of a row of balls as rolling elements sandwiched between raceways. They can accommodate axial and radial loads, but are limited to low weights. They require minimal maintenance and are easy to install. They have low friction and low noise and are suitable for high-speed applications such as electric motors
