Deep groove ball bearings were originally listed as radial ball bearings, which are the most widely used rolling bearings. It is characterized by low friction resistance and high speed. It can be used on parts that can bear radial load or combined load acting both radial and axial. It can also be used on parts that bear axial load, such as small power motors, Automotive and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

Deep groove ball bearings are the most common type in 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. There are two types of deep groove ball bearings: single-row and double-row. The deep groove ball bearing design is also divided into two types: sealed and open. The open type refers to the bearing without a sealed design. The dust seal cover material is stamped from a steel plate, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.

Deep groove ball bearings are mainly used to support radial loads, but they are also commonly used to support combined radial and axial loads. Especially when the speed of mechanical equipment is very high, when the thrust bearing is not suitable, this bearing can be used to bear bidirectional pure axial load, and it requires no maintenance during work. It is a kind of bearing with low price and wide application.

--- Deep groove ball bearing models are:

--- Deep groove ball bearing (60000 type);

--- Deep groove ball bearing with outer groove (60000N type);

--- Deep groove ball with dust cover on one side and stop groove on the other side Bearing (60000-ZN type);

--- Deep groove ball bearing (60000-2ZN type) with dust cover on both sides and retaining groove on the outer ring; deep   groove ball bearing (60000Z type) with dust cover on one side;

--- Both sides Deep groove ball bearing with dust cover (60000-2Z type);

--- Deep groove ball bearing with sealing ring on one side (60000-LS type, 60000-RZ type); Deep groove ball bearing with sealing ring on both sides (60000- 2LS type, 60000-2RZ type);

--- Deep groove ball bearing with flanged outer ring (type F60000);

--- Deep groove ball bearing with flanged outer ring on one side (type F60000-Z);

--- Deep groove ball bearings with flanged outer ring (F60000-2Z type)

According to the size of deep groove ball bearings, FQN can supply as follows:
