Deep groove ball shaft is widely used

Deep groove ball bearing is a common type of rolling bearing. The basic deep groove ball bearing is composed of an outer ring, an inner ring, a group of steel balls and a group of retainers. There are two types of deep groove ball bearings: single row and double row. The type code of single row deep groove ball bearing is 6, and the code of double row deep groove ball bearing is 4. The utility model has the advantages of simple structure and convenient use, and is a kind of bearing which is widely produced and applied. Deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can withstand large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also very high. Deep groove ball bearings are simple in structure and easy to achieve high manufacturing accuracy compared with other types, so they are easy to be produced in series and in large quantities with low manufacturing cost and are widely used. In addition to the basic type, deep groove ball bearings also have various variant structures, such as: deep groove ball bearings with dust covers, deep groove ball bearings with rubber seals, deep groove ball bearings with stop grooves, deep groove ball bearings with large load capacity with ball mounting notches, double row deep groove ball bearings. Deep groove ball bearings can be used in gearboxes, instruments and meters, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, and engineering machinery, Yoyo ball, etc
