Deep groove ball bearing
Deep groove ball bearings are the most common types of rolling bearings. A basic deep groove ball bearing consists of an outer ring, an inner race, a set of steel balls, and a set of retaining structures. Deep groove ball bearings are of two types, single row and double row. The deep groove ball structure is divided into two kinds of sealing and open structure. The open type means that the bearings are not sealed. The sealed deep groove ball is divided into dustproof sealing and oil tight sealing. Dust seal cover material for steel stamping, only to play a simple way to prevent dust into the bearing raceway. The oil proof type is a contact type oil seal, which can effectively prevent the grease from overflowing in the bearing.
Single row deep groove ball bearings, type 6, double row deep groove ball bearings, code number 4. The utility model has the advantages of simple structure and convenient operation, and is the most popular and widely used type of bearing.
Deep groove ball bearings are mainly subjected to radial load and radial load and axial load simultaneously. When it is only subjected to radial load, the contact angle is zero. When the deep groove ball bearings have larger radial clearance, they have the performance of angular contact bearings and can bear larger axial load, and the friction coefficient of deep groove ball bearings is very small, and the limit speed is very high.
Deep groove ball bearings are simple in structure and easy to achieve higher manufacturing accuracy than other types, so they are easy to be manufactured in large quantities and have lower manufacturing costs. Deep groove ball bearings except basic types, there are a variety of variant structure, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber sealing ring, type deep groove ball bearings, deep groove ball bearings with large load capacity of ball filling gap, double row deep groove ball bearing.
