Structure and characteristics of single row radial ball bearings.

Single row radial ball bearings, type code 0000 Features:
1.single row radial ball bearings are simple in structure and easy to use. They are the most common type of bearings used in machine construction and equipment maintenance.
2.single row radial ball bearings are mainly subjected to radial loads and can also withstand a part of the unidirectional axial load. However, the axial load shall not exceed 70% of the residual load of the received radial load.
3.single row radial ball bearings have low friction loss and high limit speed. The allowable speed of the light and medium series bearings can reach tens of thousands of revolutions per minute.
4.single row radial ball bearings are easy to install and maintain.

The structure and use characteristics of single row radial ball bearings:
1. The basic type of single row radial ball bearings: Type 0000 single row radial ball bearings are the basic type of this type of bearing. The most commonly used, for example: ultralight 100, light and narrow 200, medium and narrow 300, heavy and narrow 400 bearing. Such single row radial ball bearings can be used in general installation, use, sealing, and fitting parts without special requirements. It is widely used in a variety of machines, such as construction machinery, machine tools, motors and so on.
2. Single row radial ball bearings: The 5000 type outer ring has a retaining groove. The 150,000 type has a retaining groove on the outer ring and a dust cover on the other side. The single row radial ball bearings have a rectangular groove for releasing the moving ring on the outer ring. After the retaining ring is inserted, the axial fastening of the bearing in the hole of the box can be simplified, and the hole of the box can be made into a through hole, thereby Reduced part size.

    3. Single row radial ball bearings with dust cover: The single row radial ball bearings of type 60000 have a dust cover on one side, and the 80,000 type has a dust cover on both sides. In the case where it is difficult to separately lubricate and inspect the lubrication, it is inconvenient to use such a bearing, and there is a gap between the dust cover and the inner ring. The single row radial ball bearings with dust cover on both sides are filled with the right amount of grease, so there is no need to clean and add lubricant during installation. It is not necessary to add grease during the allowed lubrication period.

    4. Single row radial ball bearings with seals: 160000 type single row radial ball bearings with a seal on one side; 180000 type with seals on both sides. This kind of single row radial ball bearings is used for sealing parts with high requirements. There is no gap between the sealing ring and the inner ring. It is a contact type seal and has better sealing effect than a bearing with a dust cover, but the rotation speed is limited. The single row radial ball bearings with seals on both sides are filled with suitable grease during manufacture, so do not need to be cleaned before installation. No grease is required during the allowed lubrication period.

    5. Single row radial ball bearings with a felt ring: 200000 type single row radial ball bearings with a felt ring on one side, 120,000 type outer ring with a snap ring, one with a felt ring; and the inner ring protrudes to one end Model 520,000 and outer type ring type with a stop groove of 620000. This single row radial ball bearings can strictly prevent dirt from invading from one side. Type 30000 is a single row radial ball bearings with a felt seal on both sides. On the outer ring of the single row radial ball bearings, if the groove is made of 130,000, the felt ring can prevent dirt from intruding into the bearing and allow the grease to be filled in the single row radial ball bearings during manufacture. In order to ensure that the bearing does not need to add grease in the long-term work.

This type of single row radial ball bearings also has a type 530000 with a protruding end at both ends of the inner ring and a type 630000 with a retaining groove on the outer ring. And the type 620000 with the retaining groove on the outer ring. This type of bearing can prevent dirt from entering from one side. Type 30000 is a single row radial ball bearings with a felt seal on both sides. On the outer ring of the single row radial ball bearings, if the groove is made of 130,000, the felt ring can prevent dirt from intruding into the bearing and allow the bearing to be filled with grease during manufacture to ensure single. Row radial ball bearings do not require additional grease during long-term work. These bearings also have a type 530000 with a protruding end at both ends of the inner ring and a type 630000 with a retaining groove on the outer ring.
