How much do you know about deep groove ball bearing?

Deep groove ball bearings are the most common type of rolling bearing. Basic deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a set of cages.

What is a deep groove ball bearing?

Each ring of deep groove ball bearing has a radial ball bearing with a continuous groove raceway whose cross section is about one-third of the circumference of the ball. It is suitable for precision instruments, low-noise motors, automobiles, motorcycles and general machinery. It is the most widely used type of bearing in the machinery industry. Simple structure, easy to use and maintain. It is mainly used to bear radial load and can also bear certain axial load. When the radial clearance of the bearing increases, it has the performance of angular contact ball bearing and can bear larger axial load. This type of deep groove ball bearing has a small friction coefficient, a high limit speed, and a variety of size ranges and forms. Robust, versatile and quiet operation, high speed operation and easy installation. Single row deep groove ball bearings have a sealed design that requires no relubrication and maintenance. Single row with ball notches and double row ball bearings, suitable for heavy duty conditions.

What are the common types of deep groove ball bearings on the market?

1. Deep groove ball bearing with dust cover

Generally, it is used in the conditions where it is difficult to lubricate alone, and it is inconvenient to install the lubricating oil circuit and check the lubrication condition. Usually, the dual-purpose lithium base grease for rust prevention and lubrication injected into the bearing is 1/4~1/3 of the inner space of the bearing.

2. Deep groove ball bearing with sealing ring

Its performance, grease filling, and application are basically the same as those of the bearing with dust cover. There is no gap between the sealing lip and the inner ring of the sealing ring bearing, and the sealing effect is good, but the friction coefficient is increased.

What are the advantages of deep groove ball bearings compared to plain bearings?

1. The radial clearance is relatively small, and the radial angular contact bearing can be preloaded and preloaded to eliminate the clearance, and the running accuracy is high;

2. Under normal conditions, the efficiency of deep groove ball bearings is equivalent to that of hydrodynamic lubrication bearings, but higher than that of mixed lubrication bearings;

3. For the shaft diameter of the same size, the width of the deep groove ball bearing is smaller than that of the sliding bearing, which can make the axial structure of the machine compact;

4. The deep groove ball bearing has a high degree of standardization, is produced in batches, consumes less lubricant, is easy to seal, easy to maintain, and does not require useful non-ferrous metals, and the cost is low.
