What is the function of bearings?

Bearing is a mechanical element that limits relative movement to the desired range of motion and reduces friction between moving parts. Bearings are designed to provide free linear motion of the moving parts or free rotation around a fixed axis, and to prevent motion by controlling the vector of normal forces acting on the moving parts. Most bearings facilitate the desired motion by reducing friction. Bearings can be broadly classified according to different methods, such as the type of operation, the allowed movement, or the direction of load (force) applied to the part. FAG company can provide cylindrical roller bearings.

Rotary bearings support rotating components such as rods or shafts in mechanical systems and transfer axial and radial loads from the load source to the structure that supports it. The simplest type of bearing is the plain bearing, which consists of a shaft that rotates in a hole. Reduce friction by lubrication. In ball bearings and roller bearings, in order to reduce sliding friction, a rolling element with a circular cross section roller or ball is placed between the raceways or journal of the bearing assembly. Multiple bearing designs can correctly meet different application requirements to maximize efficiency, improve reliability and durability. FAG company can provide cylindrical roller bearings.

Basic performance of spherical roller bearings

Wear resistance

When the bearing (spherical roller bearing) works, not only the rolling friction between the ring, the rolling element and the cage, but also the sliding friction, so that the bearing parts continue to wear. In order to reduce the wear of bearing parts, maintain the stability of bearing accuracy and prolong the service life, bearing steel should have good wear resistance.

Contact fatigue strength

Under the action of cyclic load, the contact surface is prone to fatigue damage, that is, cracking and spalling, which is the main form of bearing damage. Therefore, in order to improve the service life of bearings, bearing steel must have high contact fatigue strength.

hardness

Hardness is one of the important qualities of bearing quality, which directly affects the contact fatigue strength, wear resistance and elastic limit. The hardness of the bearing steel in use should generally reach HRC61~65, so that the bearing can obtain higher contact fatigue strength and wear resistance.

Rust resistance

In order to prevent bearing parts and finished products from being corroded and rusted in the process of processing, storage and use, bearing steel is required to have good rust resistance.

Processing performance

In the production process of bearing parts, there are many hot and cold processing procedures. In order to meet the requirements of large-scale, high efficiency and high quality, bearing steel should have good processing performance. For example, cold and hot formability, cutting performance, hardenability and so on.
