Deep Groove Ball Bearings Bearing feature
Bearing feature editing
Deep groove ball bearing is the most representative rolling bearing. It is suitable for running at high speed and even extremely high speed, and is very durable and requires no maintenance. The bearing friction coefficient is small, the limit speed is high, the structure is simple, the manufacture cost is low, easy reach the high manufacturing precision. It is widely used in the industry of precision instrument, low noise motor, automobile, motorcycle and general machinery. It is the most widely used type of bearing in the mechanical industry. The main load is radial load, which can also bear a certain amount of axial load.
The axial bearing capacity of the larger radial clearance is increased, and the contact Angle is zero when the pure radial force is borne. The contact Angle is greater than zero when the axial force is used. The general use of the ram-wave shape retaining frame, the vehicle solid holding, and sometimes nylon frame.
After the deep groove ball bearing is mounted on the shaft, the axial displacement of the shaft or the shell can be limited in the direction of the axial clearance of the bearing, so the axial orientation of the axial direction can be made in both directions. In addition, the bearing also has a certain ability of regulating the core, which can still work normally when it is tilted 2 '~ 10' to the shell hole, but has certain influence on bearing life. The deep groove ball bearing keeps the frame of the steel plate stamping wave form, and the large bearing is used to keep the frame.
Deep groove ball bearing is the most commonly used rolling bearing. Its structure is simple and easy to use. It is mainly used to bear the radial load, but when it enlarges the radial clearance of the bearing, it has a certain Angle contact ball bearing performance, which can bear the diameter and axial combined load. It can also be used to bear the pure axial load when the rotating speed is not suitable for thrust ball bearing. Compared with other type bearings of the same size of deep groove ball bearing, the friction coefficient of these bearings is small and the limit speed is high. But it can not withstand impact, it is not suitable to bear heavy load.

Bearing structure
Deep groove ball bearing structure is simple, it is easy to achieve high manufacturing precision compared with other types, so it is easy to make a series of mass production, and the manufacturing cost is low, and the use is very common. Deep groove ball bearings in addition to the basic, along with a variety of variant structure, such as: deep groove ball bearing with dust cover, deep groove ball bearings with rubber sealing ring, a locking groove deep groove ball bearing, has the ball gap big load capacity of deep groove ball bearing, double row deep groove ball bearings.
Bearing type
Single-column deep groove ball bearing
Single-column deep groove ball bearing with dust cover
3. Single row deep groove ball bearing with dust cover and sealing ring
4. Single row deep groove ball bearing with stop and stop ring on outer ring
5. Deep groove ball bearing with ball gap
6. Double row deep groove ball bearing
The size of deep groove ball bearing can be divided into:
(1) miniature bearing - nominal diameter of bearing under 26mm;
(2) bearing of small bearing - nominal size range of 28-55mm;
(3) small and medium bearing - nominal size range of 60-115mm bearing;
(4) large bearing - nominal size range of 120-190mm bearing
(5) bearing of large bearing - nominal size range of 200-430mm;
(6) special large bearing - nominal size range of 440mm bearing.
