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, easy axial positioning,It is also easy to install inside the shell. The size of the maximum load bearing is the same as that of the standard bearing, but the inner and outer ring is filled with a groove, which increases the number of balls and improves the rated load.

Different type and load direction:

Deep groove ball bearing:

  Deep groove ball bearing is the most common type of rolling bearing.Mainly bear radial load, can also bear radial load and axial load.When it bears only radial load, the contact Angle is zero.When deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can withstand large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high.

Angular contact ball bearings:

  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 is suitable for large unidirectional axial load, the rated load of a single bearing is insufficient occasions, high speed ACH type bearings, ball diameter is small, the number of balls, mostly used in machine tool spindle.

In general, angular contact ball bearings are suitable for high-speed and high-precision rotation occasions.

Structural differences:

  Deep groove ball bearings and angular contact ball bearings with the same inner and outer diameter and width have the same inner ring size and structure, while the outer ring size and structure are different :

1.Both sides of the outer ring groove of deep groove ball bearings have double shoulder blocks, while angular contact ball bearings are generally single shoulder blocks.

2.The raceway curvature of the outer ring of deep groove ball bearing is different from that of the angular contact ball, and the latter is often greater than the former;

3. The raceway position of the outer ring of the deep groove ball bearing is different from that of the angular contact ball bearing. The specific value of the non-central position is considered in the design of the angular contact ball bearing, which is related to the degree of the contact Angle.

In terms of use:

1. the purpose is different, 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 is different, the limit speed of angular contact ball bearings of the same size is higher than that of deep groove ball bearings.
