Deep groove ball bearings

Deep groove ball bearings mainly bear radial loads, and can also bear radial loads and axial loads at the same time. If the deep groove ball bearing has a large radial clearance, it has angular contact performance.

Product introduction:

Deep groove ball bearings have a simple structure and are easy to achieve higher manufacturing precision than other types, so they are easy to mass produce in series, and the manufacturing cost is also low. They are the most commonly 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.

Deep groove ball bearings are the most representative rolling bearings and are widely used. They are suitable for high speed or even ultra-high speed operation, and are very durable and do not require frequent maintenance. This type of bearing has a small friction coefficient, a high maximum speed, a simple structure, a low manufacturing cost, and is easy to achieve high manufacturing precision. The size range and form vary widely. It is used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery. It is the most widely used type of bearing in the machinery industry. It mainly bears radial loads and can also bear a certain amount of axial loads. When a larger radial clearance is selected, the axial load capacity increases, and the contact angle is zero when bearing pure radial force. When there is an axial force, the contact angle is greater than zero. Generally, a stamped wave-shaped cage, a machined solid cage, and sometimes a nylon cage are used. After the deep groove ball bearing is installed on the shaft, within the axial clearance range of the bearing, the axial displacement of the shaft or the housing in both directions can be limited, so it can be axially positioned in both directions. In addition, this type of bearing also has a certain self-aligning ability. When it is tilted 2′ to 10′ relative to the housing hole, it can still work normally, but it has a certain impact on the bearing life. The cage of the deep groove ball bearing is mostly a steel plate stamped wave-shaped cage, and large bearings mostly use a machined metal solid cage.

Deep groove ball bearings are the most commonly used rolling bearings. It has a simple structure and is easy to use. It is mainly used to bear radial loads, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing and can bear combined radial and axial loads. It can also be used to bear pure axial loads when the speed is high and thrust ball bearings are not suitable. Compared with other types of bearings with the same specifications and dimensions of deep groove ball bearings, this type of bearing has a small friction coefficient and a high maximum speed. However, it is not impact-resistant and is not suitable for bearing heavy loads.

Tolerance

Standard deep groove ball bearings have ordinary grades, all in accordance with GB307.1.

Clearance

Standard deep groove ball bearings have internal clearances of C2, standard (CN), C3, C4 and C5 grades, all in accordance with GB4604.

Cage

Deep groove ball bearings generally use steel plate stamping cages or brass solid cages. When the outer diameter is less than 400 mm, a steel plate stamping cage is used without a post-code. When the outer diameter is greater than 400 mm, a brass solid cage is mostly used without a post-code.

Application

Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo-yos, etc.
