Characteristics and working principle of deep groove ball bearing
Deep groove ball bearings are the most widely used of all ball bearings, especially single-row deep groove ball bearings, because it USES a variety of sealing ring, dust cover and stop ball device.
The raceway of the bearing ring is formed into an arc slightly larger than the radius of the ball.The ball makes a point contact with the raceway (elliptical contact under load).
Deep groove ball bearings mainly bear radial load, but also can bear a certain amount of axial load.Deep groove ball bearings vary in size and form.Small friction torque, most suitable for adjustment of rotation, low noise, low vibration occasions.Such as: precision instruments, bass motor, automobile, motorcycle and general machinery, etc., is the most widely used in the mechanical industry of a class of bearings.Bearings can be divided into:
A. miniature bearing: D<=26mm
B. Small bearing: 28mm<=D<=55mm
C. Small and medium sized bearings: 60mm<=115mm
D. Medium and large bearings: 120mm<= d <=190mm
E. Large bearing: 200mm<=D<=430mm
F. Extra-large bearing: D>430mm
The cage is generally made of stamped steel, and now nylon cage is also widely used.
Deep groove ball bearings with sealing ring or dust cover have been standardized.They are all pre-stored with the right amount of grease.
Working principle of deep groove ball bearing
Deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load.When it only bears the radial load, the contact Angle is zero.When deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing and can bear a large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high.
Automobile: rear wheel, transmission, electrical equipment and other components.
Electrical: general motors, household appliances.
Others: instruments, internal combustion engines, construction machinery, railway vehicles, loading and unloading handling machinery, agricultural machinery, various industrial machinery.
Advanced Grease Technology - VIIPLUS Self-lubricating bearings lubricants that can extend grease life and performance of bearings.
China Manufacturer Deep Groove Ball Bearing
1:Can withstand radial load and bidirectional axial load
2:Suitable for high-speed rotation and require low noise, low vibration of the occasion
3:With a steel plate dust cover or rubber seal seal bearing in advance filled with the right amount of grease;
Deep groove ball bearing feature :
1.The most representative of the rolling bearings, widely used
2.Outer ring with a ring or flange bearing, that is easy to axial positioning, and easy to install the shell;
3.The maximum load bearing size is the same as the standard bearing, but the inner and outer rings have a trough, which increases the number of balls and improves the rated load.

VIIPLUS manufactures a full range of deep groove ball bearings.
Single row deep groove ball bearings are the most common type of rolling bearing and are used in a wide variety of applications.
Deep groove ball bearing can mainly endure radial load, and it can also endure some measurable axial load.
We also supply deep grove bearings, short column bearings, angle contact bearings and some precise bearings.

Deep groove ball bearing Installation method
A deep groove ball bearing installation method: force fit: bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, press the bearing to be pressed on the shaft are available, and then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal material (copper or mild steel), bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, the bearing can be pressed into the bearing hole first, then assembling casing diameter should be slightly less than the diameter of a hole. If the bearing ring and shaft and hole is a tight fit, install indoor ring and outer ring to pressure into the shaft and hole, at the same timeThe structure of the assembly sleeve shall be able to tighten the end faces of the inner ring and outer ring of the bearing at the same time.
Deep groove ball bearing installation method 2: heating cooperates: through heating bearing or bearing seat, by using thermal expansion will fit into a loose fit method of installation. Installation method is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearing, the bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight, to axial bearing cooling can then tighten. Bearing outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing,Can avoid to match a face to get abrade.Heating tank with bearing and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.

Calculation of friction coefficient of rolling bearing
For comparison with sliding bearing, the friction moment of rolling bearing can be calculated as follows: M= vertical Pd/2(M: friction moment, mN. M;Vertical: friction coefficient;P: bearing load, N;D: bearing nominal inner diameter, mm).The friction coefficient u is greatly affected by the bearing type, bearing load, rotating speed, lubrication mode, etc. The reference value of the friction coefficient in stable rotation under general conditions is shown below.
For sliding bearings, vertical =0.01-0.02, and sometimes up to 0.1-0.2.Friction coefficient of composite bearing: 0.03~0.18.The following is a list of commonly used friction coefficients of rolling bearings:
Rolling bearing type
Ertical friction coefficient of rolling bearing
Deep groove ball bearing
Angular contact ball bearing
Aligning ball bearing
Cylindrical roller bearing
