Bearing

Bearing is a kind of mechanical element that limits the relative motion to the required range of motion and reduces the friction between moving parts. The design of bearings can provide free linear motion of moving parts or free rotation around a fixed axis, and can also prevent movement by controlling the vector of normal force acting on the moving parts. Most bearings promote the required movement by minimizing friction. Bearings can be widely classified according to different methods, such as the type of operation, the allowable movement or the direction of the load (force) applied to the part.
Rotating bearings support rotating parts such as rods or shafts in the mechanical system, and transfer axial and radial loads from the load source to the structure supporting it. The simplest bearing is a plain bearing, which consists of a shaft rotating in a hole. Reduce friction by lubrication. In ball bearings and roller bearings, in order to reduce sliding friction, a roller or ball rolling element with a circular cross-section is placed between the race or journal of the bearing assembly. Various bearing designs can correctly meet different application requirements to maximize efficiency and improve reliability and durability.
The word bearing comes from the verb “bearing”. A bearing is a machine element that allows one part to support (i.e. support) another part. The simplest bearing is the bearing surface. By cutting or forming into parts, the shape, size, roughness and position of the surface are controlled to varying degrees. Other bearings are independent devices installed on the machine or machine parts. In the equipment with the most stringent requirements for precision, the manufacturing of precision bearings needs to meet the highest standards of current technology.
