bearingHub Bearing makes itself felt usually when it is time to replace. His fault motorists usually hear from maintenance foremen, and the nature of the noise machine. It happens quite often because the bearing is daily exposed to extreme loads. Women are also affected by climate, environment, but mostly the road surface and the load-side dynamic parts of the car – steering, braking system and drive.

Types of bearings

Just the design of the vehicle found two types – rolling bearings and sliding. And the number of their tens. Almost all parts of the vehicle are the bearings.

wheel bearings front

Bearing

This type and includes the hub bearing. It consists of two rings – external and internal, separator and rolling elements. These “body” have different shape, rotate or “ride” in the grooves created between the two rings. Depending on the shape of the rolling element bearing is still a ball or roller. In the latter case, the rollers can be of various shapes: cylindrical, needle, conical, or any other.

Bearing front hub

In cars with rear wheel drive it is the following: by type – roller, the number of rows – single-row, in the form of rolling elements – conical. In General, the node applies two such bearing. They can withstand heavy loads both radial and axial.

Service life

The Highest load, as already mentioned, the bearing suffers from uneven roads, and in our country very much. However, don't underestimate the factor of the environment such as temperature changes. If in the first case, the bearing will likely have to change, in the second it is possible to save a lubricant, whereby the friction is reduced, be a partial dirt repellent and corrosion protection. For such purposes, is well suited to various materials grease for lubrication. Because of the possibility of danger this node the vehicle should be periodically checked, about every 20-30 thousand kilometers. This is done by checking the backlash, the presence of noise when the wheel rotates. If your car has the single row bearing, it is necessary to periodically pay attention to the axial clearance and time to change the lubricant. If you have sealed bearings, you sometimes need to check the seals for integrity. The life of this site depends on the timely control and proper installation. If you resort to replacing the self-node, then first you should read the manufacturer's instructions. Some bearings are installed under pressure.

For the owners of VAZ suitable manufacturers, such as SKF, KOYO. Even better would be to install the stock factory bearings, because some motorists are convinced of the quality of such parts. This can be attributed to equipment installation, which may not be followed. So before buying bearings it is best to consult with experts, and then contact them for replacement parts.
