Deep Groove Ball Bearings
Double-Row Deep Groove Ball Bearings
Deep groove ball bearings are one of the most common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages.Deep groove ball bearing has a wide range of sizes and with simple structure, standardized machining process, reliability, durability and high-cost performance. Deep groove ball bearings can bear axial load in both radial and light axial directions and are easy to install at low maintenance costs.They have low friction torque and are optimized for low vibration and low noise, which are suitable for high-speed operation.
Applications: electric motors and generators, agriculture, material transportation, industrial gearboxes, food and beverage, industrial pumps, industrial fans, vehicles, etc.

The double-row design allows for a significantly higher load carrying capacity while retaining the bearing’s low friction characteristics. Double-row approaches are usually slightly more comprehensive than their single-row counterparts, making them almost as versatile and practical.
The main drawback of double-row deep groove ball bearings is that they do not come with seals or shields, though some may be fitted with cages. These cages assist with installation and assembly but are susceptible to mechanical stresses during operation. It’s vital to choose the right cage type for the application, especially as some cage materials are sensitive to particular lubricants.
Features of double row deep groove ball bearings
The inner and outer ring raceways’ double row deep groove ball bearings are arc-shaped deep grooves. The radius of the track is slightly larger than the radius of the ball. Double Row Deep Groove Ball Bearing has a small coefficient of friction, high limit speed, simple structure, low manufacturing costs, and easy to achieve high manufacturing accuracy.
When the radial clearance of the bearing increases, with the role of angular contact ball bearings, it can withstand a relatively large axial load while more suitable for high-speed rotation. It is bearing in the shell hole and shaft relative to the tilt 8′ ~ 16′ still be a typical application but will affect its life use. In the case of high speed and not being recommended to choose thrust ball bearing, you can select this bearing to bear pure axial load.
Double Row Deep Groove Ball Bearings usually choose a two-part composite steel plate stamping cage. Still, larger size or high-speed bearings choose solid cage, such cage with stamping cage is the same by the ball guidance, high-speed deep groove ball bearings cage is usually guided by the inner ring or outer ring retaining edge.
Application of Double Row Deep Groove Ball Bearing
Deep groove ball bearings are the most representative rolling bearings, suitable for high speed or even very high-speed operation, and very durable. They were widely used in automobiles, home appliances, machine tools, motors, pumps, agricultural machinery, textile machinery, and many other industrial fields. Its production accounts for more than 70% of the total production of bearings, is the domestic production of high, the most widely used, and the price to be lbelowlass of bearings.
Double Row Deep Groove Ball Bearings are very suitable for single row deep groove ball bearings in bearing configurations where the load-carrying capacity of single row deep groove ball bearings is insufficient.
Compared with other bearings of the same size, double row deep groove ball bearings have a lower coefficient of friction, lower vibration and noise, higher limiting speed, and higher precision, making them the preferred bearing type for customer selection. Deep groove ball bearing structure is relatively simple, easy to operate, produces large quantities, and has a relatively wide range of applications of a class of bearings.
