What is the difference between ball bearing and deep groove ball bearing?
Deep groove ball bearings, angular contact ball bearings are the typical rolling bearing, widely used can bear radial load and axial load, two-way is suitable for high speed rotation and requiring low noise, low vibration, steel plate with dust cover or rubber sealing ring seal type prefill the grease inside the bearing, outer ring snap ring or flange bearing axial positioning, easy and convenient for the installation of the shell, the biggest duty bearing size is the same with the standard bearings, but inside and outside the circle and a filling slot, increase the loading quantity, raise the rated load.
Different types and loading directions:
Deep groove ball bearing:
Deep groove ball bearings are the most common type of rolling bearings.Mainly bear radial load, but also can bear radial load and axial load.When it only bears radial load, the contact Angle is zero.When the 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 the deep groove ball bearing is very small, and the limit speed is also very high.
Angular contact ball bearing:
Between ring and ball contact Angle, standard contact Angle is 15/25 and three kinds of 40 degrees, the larger the contact Angle, the greater the axial load capacity, the smaller the contact Angle is helpful for high-speed rotation, the single bearing can bear radial load and one-way axial load, the DB combination, combination of DF, and double row angular contact ball bearings can withstand radial load and axial load, two-way DT combination suitable for one-way axial load is bigger, the rated load of a single bearing insufficient, high-speed use ACH type bearing, ball diameter is small, numerous, mostly used for machine tool spindle.In general, angular contact ball bearings are suitable for high speed and high precision rotating occasions.
Structural differences:
Deep groove ball bearings and angular contact ball bearings with the same inside and outside diameters and widths have the same inner ring size and structure, while the outer ring size and structure are different:
1.Deep groove ball bearing has double shoulder on both sides of outer ring channel, while angular contact ball bearing is generally single shoulder.
2. deep groove ball bearing outer ring groove curvature and angular contact ball is different, the latter is often greater than the former.
3. The difference between the outer ring groove position of deep groove ball bearing and the angular contact ball bearing is that the specific value of the non-central position is considered in the design of angular contact ball bearing, which is related to the degree of contact Angle.
In terms of use:
1. the two different purposes, deep groove ball bearing is suitable for small axial force and radial force, under, axial-radial joint load and torque load, and the single angular contact ball bearings can bear radial load, large axial load (vary with different contact Angle), twin pairs (varies with the pairing) can be subject to bi-directional load and torque load.
2. The limit speed of angular contact ball bearings of the same size is higher than that of deep groove ball bearings with different limit speeds.
