Product Description

Deep groove ball bearing is a common rolling bearing with the following characteristics:

1. Simple structure: Deep groove ball bearings are composed of an outer ring, an inner ring, a set of steel balls, and a cage, with a simple and compact structure.

2. High load-bearing capacity: Deep groove ball bearings can withstand large radial loads and certain axial loads.

3. Wide range of applicable speeds: Due to its simple structure and low friction, deep groove ball bearings are suitable for high-speed rotation.

4. Easy installation: Due to the separation of the inner and outer rings, the installation is convenient, and the bearing performance can be controlled by adjusting the bearing clearance.

5. High precision: Deep groove ball bearings have a certain level of accuracy and can meet different precision requirements for applications.

Deep groove ball bearings are widely used, including but not limited to the following fields:

1. Mechanical equipment: Deep groove ball bearings are suitable for various types of mechanical equipment, such as motors, generators, fans, pumps, etc.

2. Automotive industry: Deep groove ball bearings are widely used in automotive transmission systems, steering wheels, generators, starters, and other parts.

3. Agricultural machinery: Deep groove ball bearings can be used in agricultural machinery for harvesters, seeders, sprinkler equipment, etc.

4. Electronic equipment: Deep groove ball bearings can also be used in electronic devices, such as computer hard drives, printers, etc.

The types of deep groove ball bearings include open type, iron cover, and rubber cover, which are different choices for bearing sealing forms. The differences between them are as follows:

1. Open bearings: Open bearings do not have any covers or sealing devices, and the bearing environment is directly connected to the outside world. This type of bearing has a simple structure and is easy to install and disassemble, but has low protection against dust, foreign objects, and liquids.

2. Iron cover bearing (2Z): Iron cover is a metal cover that covers the end of the bearing, providing good sealing performance and protective effect. The iron cover can effectively block the entry of dust and foreign objects, keep the inside of the bearing clean, and to a certain extent inhibit the loss of lubricating grease.

3. Rubber cover bearing (2RZ): Rubber cover is a cover made of rubber or synthetic rubber material, which is adhered to the end of the outer ring of the bearing, forming a soft sealing interface. The rubber cover has good elasticity and sealing performance, which can effectively isolate external dust, foreign objects, and liquids, providing a higher level of protection ability.

It should be noted that the selection of open type bearings, iron cover bearings, or rubber cover bearings depends on the specific working environment and requirements. Open bearings are suitable for relatively clean environments, while iron and rubber cover bearings are more suitable for providing better sealing and protection under dusty, humid or high-speed working conditions. When choosing, it is necessary to comprehensively consider the application scenario and requirements.
