What's deep groove ball bearing?

 

 

Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used roller bearings. They are characterized by low friction resistance and high speed. They can be used on parts that bear radial loads or combined loads of radial and axial forces at the same time, and can also be used on parts that bear axial loads, such as low-power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

 

 

 

Advantages of deep groove ball bearings

 

Strong versatility and wide application

It can simultaneously withstand radial loads (forces perpendicular to the axis) and a certain amount of bidirectional axial loads (forces along the axis).It can be found in almost all industrial equipment, household appliances, automotive parts, power tools, etc. that require rotational motion.

Low friction and high speed

Rolling friction (between the ball and the raceway) is much smaller than sliding friction, so friction loss is small and heat generation is low.Able to achieve very high rotation speeds (good high-speed performance), especially suitable for high-speed operation occasions

Low noise and vibration:

If properly installed and maintained, it will run smoothly and produce relatively little noise and vibration, making it suitable for use in situations where noise requirements are high (such as household appliances and precision instruments).

Good running accuracy and stability

The manufacturing precision can be very high, and different accuracy levels (such as P0, P6, P5, P4, etc.) are available to meet the requirements of different applications for rotation accuracy and running smoothness.

The Structure of Deep Groove Ball

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 structure is also divided into two types: sealed and open. The open type means that the bearing does not have a seal structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof seal. The dust-proof seal cover is made of stamped steel plate and only serves to simply prevent 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.

 

Bearing structure:
Deep groove ball bearings have a simple structure and are easier to achieve higher manufacturing precision than other types, so they are easy to mass produce in series, with low manufacturing costs and are widely used. In addition to the basic type, deep groove ball bearings also have various variant structures, such as: deep groove ball bearings with dust covers, deep groove ball bearings with rubber seals, deep groove ball bearings with retaining grooves, deep groove ball bearings with large load capacity and ball notches, and double-row deep groove ball bearings.

Bearing type
Deep groove ball bearings are mainly used to bear radial loads, but are also often used to bear radial and axial combined loads. Especially when the mechanical equipment has a high speed and thrust bearings are not suitable, this bearing can be used to bear bidirectional pure axial loads and does not require maintenance during operation. It is a low-priced and widely used bearing. The deep groove ball bearing models are: deep groove ball bearing (60000); deep groove ball bearing with a retaining groove on the outer ring (60000N); deep groove ball bearing with a dust cover on one side and a retaining groove on the outer ring on the other side (60000-ZN); deep groove ball bearing with dust covers on both sides and a retaining groove on the outer ring (60000-2ZN); deep groove ball bearing with a dust cover on one side (60000Z); deep groove ball bearing with dust covers on both sides (60000-2Z); deep groove ball bearing with a seal on one side (60000-LS, 60000-RZ); deep groove ball bearing with seals on both sides (60000-2LS, 60000-2RZ); deep groove ball bearing with flange outer ring (F60000); deep groove ball bearing with flange outer ring and dust cover on one side (F60000-Z type); flange outer ring deep groove ball bearing with dust cover on both sides (F60000-2Z type) 11 types in total

 

The size of deep groove ball bearings can be divided into:

 

Miniature Bearings Bearings with a nominal outer diameter of 26 mm or less
Small Bearings Bearings with a nominal outer diameter range of 28-55 mm
Small and Medium Bearings Bearings with a nominal outer diameter range of 60-115 mm
Medium and Large Bearings Bearings with a nominal outer diameter range of 120-190 mm
Large Bearings Bearings with a nominal outer diameter range of 200-430 mm
Extra Large Bearings Bearings with a nominal outer diameter of 440 mm or more
